i have replaced my pypes violators for racing buillts because the pypes weren't loud enough now i feel like i opened it up to much. I think i have lost some power it just doesn't feel the same whats the loudest muffler thats will restore my back pressure and give me my tq back?

I installed an o/r x pipe and my car also feels like it lost power. im contemplating on putting the stock h pipe back.

On a boosted car you will feel a difference. If these numbers are shown on the dyno idk. I plan on putting cats back on my car. Feels like it is lacking power as well.

Picture this: Imagine a hose, you turn it on and let the water come out, it just flows out the end. Now put your thumb on the end for a brief second and then release, the water shoots out very rapidly! If you can apply this to a car you can understand that by having the cats on you can hold the boost in for just a little bit longer.

i just noticed alot more tq from the violators but it just wasn't loud enough and i have a catted x pipe

03Gtmustang · September 6th, 2008, 12:20 AM

any suggestions?

00redgt · September 6th, 2008, 12:22 AM

prob cause u had more backpressure with the violators the race bullets are more like a open pipe

03Gtmustang · September 6th, 2008, 12:24 AM

i get that but i was asking if there is a louder muffler that will restore the backpressure i like how loud my car is but i would like to feel the power as well

hmm, bullet mufflers are louder than any other mufflers with a catted pipe.....so sorry, cant help.

03Gtmustang · September 6th, 2008, 12:32 AM

whats the loudest chamber muffler i think that will restore my backpressure

ShapeShifter · September 6th, 2008, 12:34 AM

Mac or Flows i would guess, i've heard flows dumped with a catted h pipe and sounded really nice....is an off-road pipe an option? if so, bassani and an off-road x is awesome.

03Gtmustang · September 6th, 2008, 12:37 AM

i like to keep the catts whats the difference in the mac compared to flows and what kinda flows?

ShapeShifter · September 6th, 2008, 12:45 AM

not much difference at all, people will say MAC sounds difft than Flowmasters, but to "me" they sound almost the darn same, and any 2-chamber Flowmaster muffler will do.

couple of vids:

Although I'm pretty biased towards Borlas, the Stingers I have are pretty loud with my catted Bassani X-pipe.
