help me out guys!!!

i just don't know which exhaust to get....

i'm looking at Eisenmann Race, RPI Gt, and ASR. Each one sounds good in its unique way so it's really hard to decide... i'm pretty sure that i'm not the only one went through this...

I currently have the Eisenmann Race Section 3, however that was way before the RPI & ASR released their exhausts. I love the E-Race, however I doubt if they show any power gains at all. They are merely about F1 sound only. As for RPI & ASR, they provide both an amazing F1 sound with proven gains. If you intend to go with RPI, I suggest to go with Sect. 1 & 3 and if you want it to become more agressive you then can get Sec. 2.

Best of luck in your choice.

Handdoc, I'm not sure about ASR, but RPI ST exhaust is not extremely loud like the E-Race. The RPI GT is a bit more agressive than the ST.




Moji, you can check out these interesting threads. Some include video clips, pictures, and personal feedback from members. It might ease your decision making:

  19. RPI GT Headers & Eisenmann Race Exhaust (Many Mini Clips Inside!)
One word of advice, you need to be very careful when combining different sections (1,2,3) from different vendors. Some might add gains, however some on the other hand make you loose hp. One thing for sure, if you go with RPI Sect. 1, 2, & 3 you'll gain hp. Good luck!!!

I have full RPI system (headers, ST section1, GT section2&3). The exhaust tone very depend on individual preference. Both RPI and ASR proved some gain and they both lighter than e-race.

Next consideration would be, do you want the whole system, or just a section3. RPI gives you a flexibilty to choose section individually while ASR sells as one full system(section1&2&3)

Good luck with your choice
