B&B exhaust I have sounds great, but if I had it to do over, I would go RPI!

The consensus is pretty clear... RPI got the most nods.

Had the "magnaslow" on my ride, sure it sounded great, but I chopped it off and put on a RPI.
Sounds even better, and with the RPI Scoops in, my butt dyno is telling me it's quicker as well.
Hope this helps.

RPI. I had the Eisenmann and wasn't too happy with the sound. I don't have RPI, but I've listened to the sound clips. If I were to upgrade my exhaust again, I would definitely go with them.
By the way I like my eisenmann...
...but i would not mind trying RPI
