i already have my exhaust done but does anyone else running some type of muffler cause i want to know how it sounds. mine is real deep and i dont have the last muffler on anymore i just took it of and ran more pipe to the back

 

once again once you take stock exhaust off- it voids warranty.. best bet is to go to an exhaust shop and have them put on a cat back properly. you can get alot of different sounds depending if you want resonating, or non resonating... make sure you have computer reprogrammed, or any horsepower gains will be lost

 

try ol' school magnaflow muffler, then remove resonator pipe...replace it w/ 3' pipe...sounds agressive!!!

 

Battlez Exhaust
RS Exh Tip Size (mm): 101.6
Center Pipe Size (mm): 50.8
Noise db: 90
It's sweet!

 

total cost??

 

The Exhaust was around $200 or so.....I got a good deal through a shop.

 

Most cases the bigger the pipe the deeper the sound, but i wouldnt go over 2.5inch on a 4cly, you will loose too much backpressure, and rob hp.

 

I think you could get away with 3.0 inch.............

 

no you couldnt, you could physically, but it would be pointless, you would loose a ton of HP im telling you not enough backpressure.

 

i, guess 3.0 will add up some power, but the weight will kill the ratio.
