whats the best? HP increase? thanks!

I would say only sound would be increased if changing only mufflers, but please somebody correct me if I'm wrong... I heard good things about Renntech, Eisenmann exhausts systems.. also you can increase exhaust sound by removing resonator and sec cats.. do search i think you can find a lot of info ...

Eisenmann claims roughly 6% hp increase on their race model exhausts as shown on their website. RENNtech's exhaust I think as well is just for sound.

I have Eisenmann race... I still need to go back to the place i did my stock dyno at... It really is not something that you will feel. get the full exhaust and a pulley if you want to go fast

They are all in the 3K range for mufflers, and the most you are going to get is sound.. Don't count on HP from this mod.

My thoughts exactly. I'm going for cat-delete/headers first for power.

My Renntech makes all kinds of noise, but didnt get me any power.
