Which exhaust system would be better?
I currently have an Eisenmann Race and AA X Pipe with HFC. I am looking at the full Akrapovic system. But does anyone know which system would give me performance gains? The Eisienmann Race give pretty good power gains and so does the AA X pipe. But the Akra is lighter. Would anyone be able to chime in? And what about volume and sound? I love the Eisenmann race. Makes sounds that hit the spot man! There is not much on the Akra yet so I still dont know what it would sound like. Hope you guys would be able to chime in!

Waste of money?? What kind of hit will you take swapping out? You won't gain any power just save some weight. Maybe even lose power.....

I would say so.... Eisenmann Race makes more advertised HP than the Akro mufflers. Midpipes are very similar so I'd say +/- 2 HP maybe in either direction.
This stuff is not rocket science. The advantage of Akro is the beauty and not any performance advantage over reputable competitors. The weight savings is nice too. But, lots of dough for nothing IMO. What tune do you have? Filter? Do them with the savings! Quote:
