Plan on swapping my existing 2 ½” exhaust system, see signature, with a 3“ system. The problem is, I want to use a 3” X-pipe but don’t know where to install; before or after the resonator. I want to use a resonator because I believe otherwise the exhaust will be too loud.

I will and must use the Hooker shorty headers, no cats, X-pipe, resonator and MagnaFlow dual tip mufflers.

Here are the parts I plan on using:

I will be grateful for any suggestions

the X pipe goes inplace of the resanator.
this is what i did on mine.

y do u want an X pipe?
there is no point to install that if not cutting out the resanator.

I don’t think you know the function of an X-pipe. If you would have read my post more carefully, you would have noticed that I said I want to use a resonator because I’m afraid of the exhaust being to loud.

Would anybody know of a 3” resonator with an integrated X-pipe, this would surely work also or even better??
MagnaFlow has one, but it’s only 2 ½”, part# 14386!!

I still would want to know which to mount first in case I can’t find one as stated above. What length after the shorty header collector should the X-pipe be welded in.

I met a guy with a 92ZR1 this weekend with 3in.B+B X Pipe and no resonator but no headers.The car was much quieter than I expected.
With what I actually heard I don't think you'll have a problem with just the X Pipe.

vettef6

AQUADEN, did he use cats; as you know I am not???

Just using an X-pipe and 3" straight through mufflers, I don't know; should be very loud.

The shorty headers compared to the stock manifolds make no difference in sound.

redbullapril23

use stock mufflers and an X pipe.

i just dont see the function of putting an X pipe after the resanator or even before. the X pipe allows for better flow and distribution but teh resanator and mufflers do the oppisite. they distupt the flow to cancel out noise.

i just dot really see much room or reason to add one before or after the resanator.

i am running straight pipes with a 3inch x pipe with lt headers. and that is loud!

now r u getting an after market resanator?
imho its either 1 or the other.


im not trying to shoot you down im just trying to understand what you are tryin to accomplish with the x pipe.
seriously!

This is what you need. 3" resonator with the tru-x core.

ericcer

That is what I have. It does hang down just a little bit compared to the stock one.

vettef6

What do you mean with "tru-x core"??

The 3" muffler #12469 would work as a resonator also, but with a smaller spacing; which would be better don't you think??

TM-Z06

You're looking to add a 3" X-pipe as well as a 3" muffler/resonator - correct? The link I added kills 2 birds with one stone. It's a 3" muffler/resonator......and an X-pipe. The tru-x core means the internals of the muffler/resonator take a "X" path

How about a Bassani X-pipe/ Resonator..

I have a dual 3" in/out one it is a 28" can with the X-pipe and resonator.

I bought it through Vinci Performance.. it was $225

DieL

here's my .02


want loud and extra 2 hp on top? use x pipe

want quieter and 2 less hp use resonator.


your choice. using both is senseless. The resonator will be the restriction in your flow. adding an x pipe will do nothing. X pipes work if the flow is optimal. Having shorty headers imo may be the biggest restriction right there.

vettef6

TM-96CE, thanks for the tip!! The mufflers with the smaller spacing do not have the tru-X core.
The Bassani X-pipe/resonator is made of SS but is also about 2 1/2 times the price.
So here is what I'm going to get:
3" X-pipe/resonator part # 12599
3" mufflers # 14288 with 3" inlet and 2X 2 1/2" outlet
don't know which Tips to buy yet.

Thanks for the info guys

Not what you're looking for but how's this for a contraption...H -> Resonator -> X. This what the previous owner did to my Corsa exhaust. I must say, it sounds awesome like that.

I have the 3" B&B's with TPIS long tubes, no cats, no resonator and 3" Dr Gas x-pipe on my 385 stroker, and it sounds mean, but it's not so loud to be obtrusive in the cockpit. Mine is a 6-spd though, and the A4 would probably have more resonation with this setup.

whats hte cleanest way to find out where an X pipe should go? ive heard you can paint the pipes and where they stop/start burning is where the center of the pipe needs to go but that will make my exhaust looks nasty. ive also heard you can put masking tape on the pipes and read the same thing. i would think this would be a better method since you can just peeel the tape off when u are done. burnt or not. anyone ever try this?

tjwong

Mike I have the identical setup to your car. There is a felt difference between the BB resonator and the Dr Gas X pipe. Mine does have some resonance and the difference between the resonator installed or not is that the resonance RPM level is moved to a slightly higher RPM. But as I mentioned I have a felt gain in low RPM torque with the X pipe and a snappier throttle response in my car.

My 350ci LT1 used to have some resonance using stock manifolds, no cats, Borla resonator and Walker mufflers. Changing to a 396ci and Hooker shorty headers, I have no resonance at all.

See what the new 3" system, like stated above in my post, will do in regards to resonance.

I use an "H" instead of "X"...same priciple. I just installed my new Corsa system and like in the picture above, the X or H goes before the resonator.

I love the sound of my car!!

It's not for everybody, but most people that hear it tell me it's what a Corvette should sound like.
