Hey all, i want your opinions on my first mod: Perrin 3'' Catback exhaust, dual tip. (http://www.jscspeed.com/wrx/wrx_base.html).
Will i need an CEL fix if i got this mod?
I've heard that there aren't many problems that are cause by a catback on a stock car, but are there some i should be aware of, and how can i fix them?
Is it an easy install (im not going to do it myself tho)?
I plan to make sure i cool down my car before turning it off, as i do now. I want to make my second mod a COBB AccessPORT (I know this is a popular first mod, but this will be my second due to certain circumstances).
Any answers, comments, thoughts are greatly appreciated.
