My younger son lives in Dry Ridge in Grant county. Probably going to do a detailing trip to Arizona in the fall, so hopefully I'll have time in the next couple of months to visit my son in KY.

 

x2 I wish I hadn't already spent almost 1k in my exhaust or if jump on this

 

Great pic on the sig!

 

Don't do it. You'll kill the performance aspect by "choking" the exhaust. 2.5-stock sure, but I realized that was killing my performance. 3" to stock would be overkill.

 

Yeah it wouldn't be ideal. I've only got a near-stock DE-K though, so I doubt 3" is worthwhile anyways.

It would be good to know if the Flange for the muffler pipe is in the same location as stock though, that would be useful information. Especially for those who may want to opt for a different muffler to keep the noise down.

 

Was interested in this like a year plus but saved and waited and got the Cattman one no regrets even on the dollar aspects 130 bucks would be nice to save but oh well... maybe somebody in Cali will pick one up and maybe I can hear if they are near by....

 

I don't think it will sound any much different then the catt-man with the stock muffler

 

Based off of ????

 

Base off the fact that when it all comes down to it if your using the stock muffler then its all just piping , Both using the same routing and diameter . (yes i know the resonator makes a difference) but if your worried about sound then a 3'' performance catt-back isn't for you

It looks like if we were able to just purchase the piping only we would be able to get the full section unlike the catt-man were u would just get the b-pipe

I also like the fact their using quality name brand magnaflow parts in this 3'' cat-back at such a great price

 

diameter*

 

I'd be down for this if it doesnt drone tooo much :/

 

Hey, there's nothing wrong with not wanting highway drone on an exhaust system. I can't deduce whether or not a 3" system would cause more drone than a 2.5" system. More noise, but deeper pitch that is less likely to be noticed..?

@SW: Yikes, that's in the middle of nowhere, but you have to drive through Louisville to get there.

 

Beautiful muffler equates to? Id take a borla proxs over that any day. and on any old school id take a flowmaster over that ish.

smh

Don't know what Caftman uses but don't need a Magnaflow brand on it to say it is a good @$$ exhaust everybody just thinks its a muffler and I say no full 3" catback...they be like what....

 

Yeah, middle of nowhere, but they do have a Walmart now.

I'll hit you up when I figure out when I am going up there next.

 

I had that same tip on my 3.0 and it sounded great! fair price. if i still had my max i would buy it.

 

That 3" Cattman and a stock muffler don't adapt to each other!!! The 3" midpipe almost swallows the OEM flange of the rear muffler assembly!!! It's too big of a mismatch...nothing like how the Oem muffler fit on the 2.5" Cattman bpipe!!! So speak of what you really know........!

Cattman's muffler/resonator are hand built in their fab shop....and I'll say they're pretty damn impressive!

 

I would still buy Cattman for those minimal savings. Have you not heard Cattman exhaust?

Agreed

 

So how long til someone gets one of these and installs it. so we can hear sound clips

I maybe getting one of these muffler to replace the twin loop some day.........maybe ......MUGEN twin loop is looking pretty good too . I guess it all depends if the obx becomes a road scraper after i drop it

 

The exhaust is in the mail, should arrive tomorrow or wednesday. Will post up videos once installed!

How does the twin loop sound? I'm skeptical of it's design lol.

Okay guys if you got some comments on that muffler leave it to the other thread discussion about it please. http://forums.maxima.org/5th-generat...3-muffler.html


Update: Exhaust comes in tonight...more pics will be uploaded

 

What is the rest of your exhaust consist of? Headers and a test pipe or?

 

Pictures are uploaded to the first post now!!

Just the exhaust and intake. Will be getting test pipe after I hear how this sounds first and take vids. Headers seems a more down the road mod I'll be doing.

Just by the look of this exhaust I can tell it is going to make power...straight thru means straight thru lol

I'm a little excited so I'm going to an exhaust shop now to see if they can install it today I live in a apartment and would have to use jack stands to install it, and its the SUNSHINE state.

 

AND????????? We've pretty much all installed it on jack stands in 30-45mins...... Well and least with Cattman catbacks I've installed in about 30 mins, but this other brand you're dealing with could take a little longer!

Not a true 3"!!!!!! Your muffler inlet isn't.......that muffler is a 2.25" inlet!!!!! Muffler is a puny 14"er.....

 

I cannot describe how much I'd like to drop a full review into this thread - I've shared it with CMax03, but it would be considered inappropriate for me to post since I've got a bit of a "conflict of interest".

So, I'll just pass along three observations:

1) I don't believe that Magnaflow makes a muffler in this style with anything larger than a 2.25" diameter inlet tube. Perhaps some detailed pictures illustrating just how this reduction is done (seems oddly hidden in the OP pics) and a discussion of the logic of going from 3" to 2.25" at the end of the catback, and how this could affect performance, would be useful.

2) A detailed list of the difference in features between this system and the 3" catback we produce (and consideration of how those features affect installation, performance and sound) makes the difference in price seem inconsequential.

3) Magnaflow components are fine, but we find it very easy to do better when we make them in-house. We only use Magnaflow parts in dual-muffler systems because two in-house mufflers are more expensive than people are willing to pay, and the Magnaflow muffs are more affordable.

I've probably said too much, but ... just ... couldn't ... restrain ... myself ... (strangling sound). I will add that if we manufactured and sold an identical system at the price shown in this post, we'd make significantly more money per unit than we do on the catbacks we're selling.

 

I do not want to hide anything at all. I'm just the person helping him with this exhaust, you guys are more expert when it comes to exhausts. Also, I need to figure this 2.25" muffler inlet out. Maybe it was just my prototype unit that got it. I will talk to Greg about this issue. I'm sure that he isnt giving 240sx's the same or else they would of noticed it right away.

Also, a reputable exhaust shop says it is going to be a little hard to install around the rear axle portion which looks like a very tight fit. I didn't go ahead with the installation just yet because I need to raise my car at least an inch.

Is it true that when you 'crimp' the 2 pipes together with the clamp they will not come apart afterwards? This makes it almost a permanent install?

 

The $530 price for the aluminized version is tempting but I'm sure I'd at least have to swap out the muffler for one that is quieter, plus get some stainless steel tips and by then, the price would be the same as the Cattman exhaust.

 

Maybe a Borla muffler would be quieter than a Magnaflow.

 

My opinion is that you are trying to be helpful and there is no reason whatsoever that any discussion about this system should reflect negatively on you.

I would confirm exactly what the exhaust shop told you. Its hard enough to work around that tight spot when all the flanges are welded onto the tubing, but when nothing is referenced and you've got not only 360 degrees rotation, but the added dimension of how far the male end is inserted, it can become very tricky in a tight spot.

As to clamping, a high quality, wide-band clamp spreads the clamping force evenly across the width and circumference of the band and it should make tight seal, but not a permanent one. Haven't noticed the clamps sent with this system (I assume they're included?) but cheap clamps with more narrow bands that do not clamp with even force around the full circumference of the tubing can sort of crush the tubing in some places and leave it too loose in others. Worst possible outcome - you still have leaks, but you can't pull the two parts apart any more. EMPHASIS - I am describing a generic possibility/outcome from using cheap clamps and I am not speaking specifically about this system.

Brian

 

There are clamps, I will post a picture of them when I get home. The only thing that I'm worried about with this exhaust is the 2.25 inlet. Hopefully its an isolated incident

 

If that muffler - or any Magnaflow muffler like it - is used, its not an isolated case. According to the Magnaflow website, it only comes with a 2.25" inlet. Anyone can check this out.

I would simply say that this system is executed very differently from the 240SX system that appears in the pictures. Maybe this is an intermediate design, and the final system is meant to be better integrated, with welded flanges and 3" tubing throughout.

 

everthing looks good up in til the point were the pipe meets the muffler whats that gray stuff on thier spakle lolz i dont see why they didnt at lest didn't try to at lest put the muffler inlet in a pipe expander and expand it to 3inch so it would slip over the pipe. i would til be down for this set up if thier willing to offer it with out the muffler hytech has a really nice muffler i want to mate it to

 

Brian, he may be using a 4"x9" oval XL Muffler as that page lists two 3" inlet / dual outlet mufflers, each at 14" long.

 

Yeah my custom 3" has magnaflows and the inlet/outlet are 3"...probably not the same muffler though....

the exhaust shop did say that the rear spot was a tight fit, but they did a great job

 

Sooo guys I am looking at the muffler and its 3". Pictures can be deceiving! Also here are all the hangers and hardware that it came with.



Did they hang it all on the stock spots only?

 

yeah those clamps........

I'll get some pics of it

 

This... I'd spend the extra bit of cash to ensure that I'm getting a quality product from an active member of the community that is willing to back up his product 100% and is not only knowlegable, but always honest about the product he sells.

Thanks for chiming in. I was curious as to what your opinion so far is. I love how you never bash another product, but just point out areas that may be of concern for potential buyers. It really says alot about not only your character, but you as a person.

And just a side note, the best sounding exhaust i've ever heard on a maxima to this day was my friend's 03 with cattman headers>fastcat>cattman catback.

 

You can see how clamps like these squish from top and bottom, but don't apply the same pressure on either side. After really torquing these down, the tubing will be slightly oval (and possibly difficult to separate again). A stainless steel band-style clamp with a single adjustment nut is ideal.

 

Huh?

If the Muffler OD is 3", then what bloody size is the Exhaust pipe? It is obviously larger than 3" based on that picture....

Not saying this is false or anything, but the pictures are showing a very different tale, there's nothing deceiving in that picture, one is bigger than the other, and I'm tempted to believe Brian on the Muffler's inlet size.

 

1. Brian, he may be using a 4"x9" oval XL Muffler as that page lists two 3" inlet / dual outlet mufflers, each at 14" long.

Nope, not an XL series muffler. Those have a satin finish and don't come with finished tips. Look how separated the stubs are in the XL dual muffler can (5.25" on center), these look closer together. The style of muffler looks like Magnaflow Street Series line, but in that line there are no dual tip mufflers with inlets larger than 2.25".

Maybe this is some sort of special run muffler they did, because there are no visible Magnaflow stamps on either side of the sheet (possibly a Magnaflow knock-off but might just be the picture quality - you can look at the 240SX muffler, but the most useful pictures of that system have been deleted from the original post) but the inlet does not appear to be 3".

BTW, not sure if this is the same muffler can, but its definitely not the same muffler/tip combo that is on the 240SX, those tips are dual wall and a different length.

2. Sooo guys I am looking at the muffler and its 3". Pictures can be deceiving! Also here are all the hangers and hardware that it came with.

Sooo, got a caliper handy? I believe it would tell a different story.

Also, someone speculated about stretching tubing. Making tubing smaller is a bit tricky and requires specialized equipment; making it larger is easier but there are limits to how much you can stretch a tube before the material gets too thin and becomes prone to cracking. You'd typically avoid increasing diameter more than 3/8" on tubing this size. [Remember that the female end has to be stretched 1/8" just to fit over a male end of the same tubing size, so if the smaller tube is to become the female end, the largest tubing that can be used for the male end can only be 1/4" larger than the smaller size.] If the tubing sizes being joined are more different than that, as appears to be the case here, the simplest approach is to goober up the gap with a lot of welding material, which can intrude into the interior the tubing if the welder isn't careful and create a big turbulence-generating mess on the inside. I think it would be possible to get at least a partial picture of the interior of this joint while looking down the inlet tube of the muffler.

I'll just toss this out in the interest of fairness. If I want to promote a product on nicoclub, I have to be a vendor, and pay handsomely for that right. I suspect that if I did something like this over there, it wouldn't go over too big with the site owners. Shouldn't BRM (owned by nicoclub) do the same?

 

Yeah just for you rookies....an inlet on most mufflers are spread/expanded to slide the approiate size tubing into itself! So if the tubing of the muffler was set up to accept a 2.25" tubing the inlet I.D will be slightly larger than 2.25, if it's setup for 2.5" the inlet will be bigger than the 2.5" tube and if the inlet is setup to accept a 3" tube the inlet I.D will be larger then the 3" tubing...and the exhaust tubing will slide into the muffler's inlet not over it like in the BRM setup!!!!! There were a few 3" inlet Magnaflow which were all single tipped mufflers, as stated by Brian, the dual tipped street series are all 2.25" inlet configurations..... People you got to understand just because something you like and that you're saving some coin on......there are gonna be some shortcuts and shortcoming to deal with...Yall will one day say WOW Cattman was building $1000+ catback systems for way less and that these exhaust systems will be around even after all the cars are gone.....Somehow and someway that money saved will result in more time spent installing or even making extra purchases to replace it's ill fate hardware....with top notch stuff!

Here's some side by side pics of Cattman & BRM:
