I have decided the first thing im going to do to my car is get the extractors and sports exhaust with cat but i can decided or know if a 3" or 5" canon would be best... i think a 5 would look better but ive been told by a few ppl that 5's are no good for non turboed cars is this true? as i want performance and looks out of this rig so i may have to make a compromise depending on what you guyz think? oh i have a 5sfe engine if this matters any, and no im not interested in a conversion lol i know the 5sfe isnt the best but i dont want to go that far with what im doing to my car... your thoughts are apprieciated.

Greddy SP2...although exhaust back in dimension is not as big...saves you from being pulled over...
