I am looking to upgrade my exhaust. I already know that I want to replace the y and b pipe with warpspeed .. I am now looking for a muffler. I am looking for one that is not loud. I want one that is a performance exhaust however dont want the loud sound. Does anyone have any recommendations. Thanks!

 

Get custom 2.5" piping welded to your stock muffler. You stay quiet and only give up 1 or 2HP over a loud aftermarket muffler.

 

how much horsepower does a WSP B pipe give and how much are they

 

I am not sure what the b pipe offers horsepower wise. I do know price is around 150 without resonator and 175 with..

 

What B pipes are can bolt on to a stock muffler with no modification?

 

Warp speed has b pipes that will fit onto both stock mufflers and also center inlet mufflers. The price is the same for both...

 

While you're at it, get their 2.5" test pipe.
Might throw a CEL but worth it.

 

What does this pipe do and what do you mean by blow a CEL??

 

It replaces your catalytic converter with a straight through pipe.
No more Cat may throw a CEL light with code P0420. "Rear Catalytic system efficiency below threshold"... Yeah no kidding because there is NO cat

 

try a 2k and up factory can. its a little better than our (4th gen) muffler and quiet to boot.
