I get people who ask me about the two all the time so here is a comparison of the two exhausts side by side. No point in a race between them because we already know the result.



In the video its hard to tell but in person its like a push compared to a bitch slap.

 

Advantage RPI.

 

RPI definitely has a deeper richer note

 

RPi has more guts in the low RPM and a meaner sound in the high RPM!

 

We wanted to do some runs and video it also but the guy prefered not to.

 

I think I have a hearing problem cause they both sound good to me. Sound is so subjective.

Does the Eisenmann car have sections 1 and 2 also like the RPI car or just section 3?

 

RPI

After I heard C's M5, I fell in love with the sound of the RPI exhaust.

 

They both sound good. The E-Race has always sounded good. In person, the volume is a huge difference. The customer was like DAMN, if I heard this comparison before, I would have got the other exhaust. The customer wanted a loud exhaust.

 

Tony does eisenmann make sections one and two? Either way both exhausts sound nice, but it's hard to tell by the video.
In person the RPI exhaust was much louder. Even Andy, the owner of the Black M5 acknowledged that the RPi set up was
much more impressive.

 

Yeah I drove Rab Dog's car (Stage 2 RPI M5) and the thing sounded wicked. Such a fierce growl. My only problem is to live with it as a daily driver.
