exhaust comparison question

[turboblack2door]

i have a greddy sp2 exhaust on my spyder now but would i see a difference if i went up to a full 3in cat back? I think i'm really after more of an exhaust note though. Any input will help thanks

Need more info. Do you just have a cat-back? What size is your exhaust now? From your profile, I would just leave the exhaust alone. If your looking for tone look into a different muffler.

the thing about that is i don't want to hack the muffler off of a greddy exhaust just to make a little more noise. and as for the car i have a 16g going on it in a couple weeks, walboro 255 fuel pump, greddy hard pipe kit, greddy type s bov, open filter intake
