Open headers, backfiring at idle
I just put on 1-5/8" Hedman long tubes and I took the car for a drive around the block. At idle it kept backfiring, I could feel it through the floor! When I'm on the gas it doesn't happen. Why does it do that? Is it bad for the car? Will it go away when I put the rest of the exhaust on? 
They sound AWESOME though. Scares the hell outa everyone
