I recently got my exhaust done cat back, 2 1/2 inch piping with a dual magnaflow muffler. my car used to backfire a little before I had the exhaust done, but now it sounds like a bomb is going off. Any Ideas of what the problem could be, or is this normal for rotaries??

 

is it a 79-80? they do that.

Make sure there aren't any leaks. That will also cause backfire.

 

it's an 82. I'm pretty sure it dosn't have a leak.

 

hmm, try taking the airpump off, sometimes that system will do that

yeah as it was said above, the faulty ACV and airpump usually make them backfire.

 

I will try that. :bigthumg:
