do many of you guys back fire alot? i backfire damn near every time I shift( and throw a decent size flame). I was wondering if it's since there arn't any exhaust valves if thats why it occurs and you don't hear the backfire on factory exhausts due to the size of the piping and the cat? p.s. i'm using the apexi n1 exhaust...does anyone have pics or info on the apexi n1 dual? or have pics of their car on a lift with it so i can get a better look at it?

 

I've backfired with a stock exhaust, and have put out sum flames with it too. You dont have a cat in ur exhaust, thats why its flammin.
