Will this work? Can I get a Cattman Y and B and bolt up to the stock muffler? I don't want the ricey can on the back, nor all of hte sound. I just want the power and the throaty sound of the Y and B and the intake I'll get.
I've always gotten at least the rear muffler section in the past but I think I'm growing up, now. Maybe.
Any help is great

no the car will explode, then will implode and the car next to you will follow suit

With a Y-pipe and B-pipe, the exhaust note from the rear section will increase, more so if you delete the resonator. But since the rear section is stock, the exhaust note will never drone into the cabin.

 

I guess my question is, will it bolt straight up to the muffler and will I be losing significant power by not getting the muffler?

 

It will bolt up. I have heard that setup and it is very tame until you go WOT. I have the Cattman y-pipe with stock b and stock muffler, and love the silence at the red lights or at idle.

 

This is exactly what I have. Everything bolts up just fine. My B-Pipe has the resonator. It's has a nice subtle growl. The Y-Pipe went right in and the B-Pipe needed some minor adjusting after install, but bolted right up. I think you'll be very happy with the set up. I don't think the stock muffler will cost you any significant power . BTW I'm noticing most of my power gain in mid range.

 

Can you post a sound clip at idle and WOT? or even email me one? Thanks

 

I agree, I only have the ypipe and intake. It is quiet at idle and when I blip the gas it burbles... basically sounds nice and at WOT, it's nice....

 

Aftermarket mufflers for your setup will give you absolutely no more power. Our stockers are free flowing enough for up to about 300 hp. I have the cattman y and budget b. The exhaust note apon crankup and idle is a low little growl. The car is still as quiet as it can be going down the road. You'll definitly feel the difference.

 

I am considering doing this as well, Cattman Y pipe and B pipe, and leaving the stock muffler in place, as I don't want a loud exhaust. However, a little extra rumble would be desirable. How much louder is the Cattman muffler compared to the stock muffler?

 

Thanks guys. Plus, it will save me a little cash vs paying 350 for a cattman rear section that is minimal gains other than looks and sound or 500+ for the complete catback. Plus, like you said, it will give me some growl and power and still be what I call "mature"...

 

I'm not sure if this helps... but I'm doing it too... I'm getting a Cattman Y some time next week and am replacing my Greddy muffler with the OEM, while retaining the 2.5" Greddy b-pipe....

 

You guys WILL be happy with the result. TRUST ME. I got fooled into getting the Powertech and hated it. I'm not ruling out the Cattman rear, but I would have to get a turbo or supercharger before considering that. I love my quiet tone.

 

I already have a y-pipe installed, considering a custom 2.5" b-pipe with no resonator and keeping the stock muffler. i figuring it'll keep it from sounding like crap as if i were to put an aftermarket muffler on, but still with a ypipe and an open b-pipe i think the sound should be more noticable in a good way, what do you guys think about this?

 

Turbos actually help to break up exhaust noise in most cases, but it's not ALWAYS true...

 

How much louder than stock is the Cattman muffler/exhaust????

 

Considerable. I have recently installed my Cattman Catback. I allready had a Cattman Y-Pipe & a Stillen intake system. I love this setup. It is louder than before but much deeper tone. The exhaust note from light to light is def much louder but at idle & above 2400 rpm....... Such as being at highway speeds in overdrive or 4th gear it is not much different until you stomp the gas. My impressions of the Cattman exhaust setup is a positive one. It def breaths much better at higher rpms thsn it did stock. But dont let people tell you it is close to stock because it aint . It will be very noticable that you have a after market exhaust.

 

Barely... http://home.comcast.net/~nathan.day/...ps/cattman.mpg

You can peruse through other clips here:

You're right... but I just wanted to add that it really depends on if we're talkin about a set-up with say only cat-back or with a y-pipe and cat-back... because the y-pipe maginifies the noise level much more if you have a higher flow muffler like the Cattman....

 

I'll be getting the Y-pipe, so I am expecting the Cattman exhaust to be louder, than without the Y-pipe. Is the Cattman muffler sound mellow, like the G35 coupe, except a deeper/lower sound? I won't care if it is a little louder, I just don't want the oh-my-God-roll-up-the-windows-and-put-in-the-ear-plugs kind of noise from my exhaust system.

 

What'd you think of the sound clip I posted? Did that help at all?

I've heard the Cattman and it is kinda like a G35 exhaust... might have a lil more rumble to it with the y-pipe... but its nothing too obnoxious... no drone at low rpms and it'll roar a lil at WOT...

 

Thanks for the sound clip Puppetmaster!! I think the Cattman exhaust will be perfect!!
I do want the car to make some noise to match it's looks and performance!

 

Looking at the dyno graph/spreadsheet Brian (Cattman) gave me, I'm seeing that they show an avg gain of 11hp/12lb-ft (stock vs Y/B Pipe). But the biggest gain (vs stock) in HP is between 4100-5200 rpm with gains between 9.3-19.3hp (again, in this rpm range) with 9.4-23lb-ft gains in this range as well. (ref: 03 Maxima 4AT w/ Y&B pipes only)

$.02

 

F23A4, those dyno references are for the stock Y&B pipe vs Cattman Y&B pipe
only. Did he give you any reference to the additional HP the rear section Cattman muffler makes? I know it's not alot, but I am curious as to how much more, 5,8,10 HP?

 

Doubt its really gonna matter... but I guess you want dyno results to prove it... I'm guessing the gains will be 5 hp tops, if at all...

 

Does Cattman make any reference to the HP gain for the rear section muffler??

 

I have the Cattman Y and BudgetB and stocker moflo- My friends are in love with the sound of the VQ when pushed and are impressed with how theres no cabin drone or backpressure for a car with an upgraded exhaust

Only set back is I've been throught a gasket where the stocker lines up w/ the b pipe in 2yrs of having the bpipe- not bad considering its ~$10 trouble if it happens

 

remember if you go with a 2.5" B the stock pipe is smaller, even if it bolts on. If you want to do this right you will need to cut the pipe off the stock muffler and replace (weld) with a 2.5" one. While you are at it, put some nicer tips on.

 

So b-pipe with resonator or no??

 

IMHO, I'd say if you plan to keep your stock muffler, go with no resonator, it'll add more exhaust sound but never drones. Its really up to you jah I've heard sound clips of a 2.5" B-pipe without resonator+a custom 2.5" rear section welded to the OEM muffler and it has a nice sound to it. I have a soundclip of Blu2k2 (I think thats is S/N) with that set-up and it sounds mellow.

 

I might not even bother with this and go loud with the y-pipe and Greddy cat-back....

 

screamin, can you send me the clip? or post it... I'll host it also if anyones interested.

 

Very good point. Matching the diameter of the B pipe will be important if anyone is planning on keeping their stock mufflers on. Otherwise you are creating a fairly significant flow restriction, that will definitely effect overall performance and HP. Why put on a Y-pipe and B pipe, only to choke the flow
at the junction of the B-pipe and rear section/muffler. There is a reason all performance exhaust systems have matching diameter pipes-to reach the maximum potential flow rate.

 

Nicely put, Turbo and theMax... I think we took it for granted that most people already knew this... good that ya posted that...
