I have Eisenmann Race and like the sound...not extremely loud....I heard the RPI is loud...depends on your preferance.
RPI, volume wise, is somewhere inbetween Eisenmann Sport and Eisenmann Race.

The eisennman sounds awesome but to this date every single dyno has shown either a loss of power or same as stock. The RPI on the other hand sounds perfect with the most amount of gains compared to any other exhaust. I say if you want to loose power go with eisennman. But if you want pure performance there is no other choice..... RPI

The RPi exhaust is designed to fit the stock hangers exactly the same as the stock exhaust.. It is truly a bolt on exhaust. It's a no brainer! Just google dyno eissenman then google RPI dyno. After some research you will learn the eisennman exhaust does not come close to the RPI exhaust in terms of performance.

Well you guys and all the other bmw forums etc-alll were right that the gains are not there and even a loss.
I remmeber an article in eurorev mag I believe-it was online. They took a stock e90 330i and put AFE intake which did show improvement oddly enough. But then they added SS exhaust and lost like 11 hp.
I dont get how a company like supersprint or eissenman who are giants in this field cant produce power.
Also I was sold because I wanted louder than sport but race was just overkill and with RPI you can put the silencers in if family is in town

Oh no....you said AFE.....:LOL
Kind of confused now, did you go with RPi or Eissenmann?
