Hey everyone. I recently had an Eisenmann quad exhaust put on which sounded amazing. Yesterday while under heavy acceleration, I heard a loud backfire which resulted in my exhaust tone now pretty much gone. While idling it still sounds deep however under wide open throttle the tone is just non existent.

I figured I would ask the experts around this section for a little help on the issue as to what could of gone wrong, so thank you in advance!

Any thoughts?

bump for you... just ordered mine and this kinda scares me.

I'm not certain of the interior construction of the Eisenmann exhaust but if I had to guess, the backfire probably repositioned and/or blew out some of the baffles or mesh material in the muffler.

Just speculation but keep driving it and give it some more revs, see if it returns to normal. I would also contact your sales rep that you bought it from.
