I would like to know a basic scale of the loudness of various exhausts available. This is assuming the exhaust (not including cats or headers) are changed and the car is otherwise BONE STOCK.

If stock is a 3/10 then how would you rate the others? Stillen, Injen, HKS, Nismo, etc...

stillen at idle 3 at WOT 8

my old setup...20 at times...3 at others

lol cuz you had the e cutouts... basically running open headers will do that

^^yes sir! and i loved it!

Greddy evo 2: a BIG 4, not loud for aftermarket. however, with HFC i heard it opens up nicely

fuji at idle 1 at wot 2 =( hahhahah 3 with my high flows.

invidia at low rpms up to 3.5 rpm about 4.

6000 rpm then definitly 9

invidia with stillen headers quiet when just rolling mean when u stomp on it

custom true dual with test pipes, 500, but with 4 resonators 2 on each side, id say 7-8

i think the pro-1 exhaust is the loudest for our cars

ask tru-play

I want one that blow up the whole street, haha. JK
How's HKS?

Yea i would like to know which exhaust people think is the loudest?

who in here has the pro-1 exhaust? tru-play? plz chime in =)

i was listening to it earlier today and starting to like it! not sure if the car had any hfc, and/or headers. i am running stock right now and plan to keep the stock cats...how does the exhaust sound by itself? (without hfc, headers etc)

not a big fan of how it looks tho.

loudest...id say the rsr HANDS DOWN
