I have an aftermarket Y-Pipe and a less restrictive intake, but my car still sounds like the exhaust is being blown through a straw.

I'm contemplating upgrading the B-pipe to 3", and if I do, then it makes sense to me to also change the muffler.

Now, I'm not looking for a lot more noise...just something that has offers less back pressure than stock without the droning noise that often accompanies some straight-through designs.

Recommendations, please?

why a 3" B pipe?? the Y pipe is only 2.5" If you plan on staying n/a i don't think there is any point in using 3", it would just be real loud especially if you don't use a resonator.

Magnaflow makes excellent street mufflers that arn't very flashy, personally I used to have one and I 'upgraded' to a droaning straight-through style muffler. Wish I had my magna still.

The place where I'm going to have the work done suggested it and it sounded like a good idea. I thought that maybe "bigger" might be better...even though I'd need to use a step-up adapter for the cat.

However, it may be moot since the 3" may not even fit the space available given how the stock b-pipe is crimped.

Other than replacing it with a pipe that has no crimps, what would be the advantage of changing out the B-pipe for one of similar 2 1/2" size?

Would a 3" pipe really produce that much more noise over the 2 1/2" stock pipe, even after I slap a muffler on it to attenuate the noise?

Three inch piping would be foolish.

3"


I had stock everything (aside from headers) on my 3.5L and made over 230 whp. So, at times I question the 'bottleneck'. I'm sure it exsists, but the more sane the N/A set-up, the less I believe the muffler, b-pipr to be a limiting factor. So unless radical N/A modding is taking place, I'd leave the stock unit in place. If your stock piece is rusted, look for an A33 replacement.

If your looking for power with little noise then just replace the stock b-pipe. Mufflers are mainly just for sound and give around 1-3 hp. If you decide to do both and get a full cat-back then you would probably like the greddy sp2 since you don't want droning. I have the cattman and I love the sound but it drones a bit more in the lower rpms than my friends greddy cat-back. Even with the full cat-back you probably won't notice the gains. Cat-backs are mainly for sound.

Why is 3" Foolish ?? If you plan on Supercharging then its completly sane. I have full 3" exhaust with NO fitment problems as far as the B-Pipe is concernced and thats matched up to a Dynomax superturbo muffler, 3" in 3" out

He never specified any S/C plans. So in turn I stated for N/A plans.

Stock is 2.25. I have a custom 2.5" catback with a Super Turbo, can only hear it up to 3 grand, nice and deep. A little raspy, but you can only hear it when next to a wall or building, or outside the car. For under $150, works for me.

Dynomax FTW...

Always been impressed whith there products, have ran ulta flo's on my mustangs and super turbos on other cars.

And for the price there hard to beat

Is the Magnaflow a straight-through design? I'm trying to avoid those types.

get a stock 5th gen muffler and get 2.5 pipes....geat low end power and nice quiet sound, but louder than stock 4th gen

dr-rjp

Was the pipe custom-made or pre-fitted?

The guy at the muffler store who's installing my AGX's offered to replace my stock B-pipe with a 3" aluminized steel pipe for only $75. Before he mentioned it, I never thought about getting a wider pipe.

Also, I don't have the jack (nor can I justify it) to lay down for a Greddy or Cattman pipe. I'd rather save my money for new rims and rubber.

If you are NA stay with 2.5" pipe... I'm still using it for my 3.12" S/C setup.

I just replaced my GReddy straight through with a Dynomax Super Turbo 17769 (20" body), 3" in/out cambered muffler. I also used a 3 disc Car Chemistry insert at the outlet of the muffler. My car is so quiet now.

Damn, i'm getting old.

I have budget y, stock cat, stock catback, and dynomax superturbo with 3.5" tip. Sounds smooth inside of the car, and quiet outside, but not that smooth, thats because of the Y pipe. Overall i think it sounds good, no rasp is present.

OK...I am getting a consensus here on sticking with a 2 1/2 if I am running normally aspirated. Not to be a "pain in the @ss, but I'd really like to know "Why?" as in "Why not a 3" b-pipe?"

I have no problem going with the consensus, but, so far, the only reason i've read as to "Stick with 2 1/2" is that the 3" would be "louder," whatever that means.

Basically, if someone can tell me why a 3" pipe would be a waste of metal (or redirect me to a site that can) from a performance or "noise standpoint, I would really appreciate it.

For example, if someone ran dynos comparing a 2 1/2" to a 3" with a NA setup, that would satisfy my curiosity.

Certainly, it is easier to keep everything the same size as stock, but, if there is no real compelling reason beyond "stick with stock" as to why I should not use a larger diameter b-pipe, I'm willing to experiment.

Some of the recommendations that I read on the forums amount to "word-of-mouth" knowledge that has been passed down from person to person without any originating source mentioned.

Or, if a source is mentioned, it is never challenged, like the bogus research that "Bob, the Oil Fraud" published about Lucas, or Cliff Knight's personal diatribe against K&N air filters.

Some people have the attitude that if they read it on the Internet, then it must be true. Not me, for one.

I have also learned that some drivers are predisposed to stock setups and are a bit resistant to deviations from it. Call it "experience." Call it "dogma." Either way, the degree to which they become incensed when anyone begs to differ is worth noting.

I wonder if, at some point in the past, some Max owners scoffed at the idea of using a 300ZX fuel filter instead of the one made for the car. Nowadays, owners regularly substitute the 300ZX filter...but I have to beleive that somebody in the past went against the conventional wisdom of the day by being the first to use it.

I might S/C my engine someday, so then it would make sense to go up to 3". Then again, I might not.

The point is that when it comes to modding my own car, I am not afraid at all of experimenting with it...unless I see credible evidence that a particular mod might potentially screw it up.

That's my story...and I'm sticking to it.

How much can I get a 5th Gen b-pipe and muffler for these days?

I got my bpipe for 200 IIRC from Cattman(check his website, pm him/email him) and 5th gen mufflers can be found either here or on ebay for 59$ or so.

What about Borla mufflers? Too expensive for what they do...or worth the price?

yea right dynomax sounds terrible.. just like a fart can if not worse.... sorry but i had one on for about 15 minutes and i returned it... it sounded terrible...

the best thing to do if u want good sound is to keep the stock y pipe and put ALMOST ANY MUFFLER ON IT.. i will sound good..

Chunger

iTrader: (1)

That's quite a blanket statement... I've had SuperTurbos on several of my cars and they are "nice" sounding. How a car sounds is very subjective. Some folks like the fart can sound or the loud obnoxious.

Which one did you have? Ultraflows or chambered ones? A Y-pipe with most straight through mufflers will usually drone at about 2500rpm. I can attest to this because I had a 70mm GReddy with 3 resonators... "tolerable" drone will depend on each owner. I'm tired of it....

f550maranello2

iTrader: (2)

holy god almighty.... 3 resonators... u should have went with 1 33 inch long 6 inch diameter magnaflow resonator like me.. i have a magnaflow muffler its the 14827 muffler.. with the warpspeed y pipe it sounds lound and drowny... with the stock y pipe i sonds great and it has a lot more power...... and no drone...

magnaflow calles their resonators mufflers by the way...

Chunger

iTrader: (1)

I still have a catalytic so that size would have been too large to fit. 6" diameter would decrease my ground clearance by 1" at the most critical area. Drone is mostly a concern with a Y (which I have). Stock Y would cost me at least 20 ponies with my SC.

So which Dynomax did you try out, though?

Cattmans Catback, all the way. It's the quietest next to stock I've been through so far, and I've used 4 different mufflers so far.

They are a quality muffler, but I haven't found anyone who has used them.

I've had borla on a 4 cylinder car before. It was a loud pitcher compared to Cattman.
