what is the loudest/most hp producing exhaust i can buy?? (i'd prefer the louder one though and am willing to sacrifice a few hp's if another system that has more is quieter)

 

I have the Injen SES dual with straight tips and it is extremely loud. Oh yeah, I also have test pipes which adds to the loudness. I have a little rasp but its all good with me. I think most people would say the Injen is one of the loudest and best quality build exhausts.

i would do the invidia or rsr exhaust with the y pipe im having a group buy on right now (pm me if interested) and then do test pipes...that would be reallllllllllllllllly loud

 

I think the loudest exhaust would be either the JIC straight single side system or the Magnaflow Ti single (made by JIC). Plus race pipes for more sound and power.
For most power I would I would say the Stillen system with race pipes.

 

I have the RSR and it is really loud, if you add a y - pipe you're gonna blow people away. I love this exhaust. Waiting for a y - pipe.

 

i highly agree with vivid...and its not like a annoying loud its more of a exotic racecar loud...i would hop on the group buy that i have going for the y pipe and get the rsr exhaust from vivid...great combination

 

the only thing i don't like about the rsr is the canister muffler look from the rear of the car. i like the clean look of just pipes coming out.

 

I have the RS*R too and love the sound. Looks worried me a little bit at first but I really like it now mainly because it looks different than most exhausts out there. Weld quality it top notch too. Plus it's great fun at the track Really turns heads when you go screaming by.

 

i am looking into the stillen exhaust and test pipes...hope they sound good

 

The stillen is a great exhaust, just a little too quite for me.

 

I would call Tom at Light Speed Performance. He will be able to help you with your question.
