This has been goign on for a while now, and im so use to it i cant tell but i need to get rid of it. It started backfiring really bad after Igutted my cat, so i dotn know if its loss of backpressure or just a crappy exhaust system. My friend said it might be spark plugs. What doyou gusy think it is and how do i fix it?

 

I think neighbors suck...

 

Could be burnt plug wire, running lean?? (I think), or do you have any bad exhaust leaks??

 

your neighbors called the cops?

 

your neighbors a dick. it might be the lack of back pressure. check for any leaks first.
