Mufflers

[GFYN]

What kinds of mufflers could i put on my car that would sound good and add performance?

[Grouch]

pretty much any. What type of sound are you looking for? Also for the best performance gain, replace all the pipes from the cat-back with 2.5-inch diameter pipes. Preferably mandrel bent, but if not crush bent will still be an improvement over the stock pipes.
