yesterday I was playing around and getting on it. I run it up to 6500 and when I shift bam...sounded like someone shot a gun, kinda scared me. my car has popped before but nothing that loud. so I try it again and the same thing. I know I had to shoot a nasty flame out of my turn down. its only really done it after I change the muffler and turn down. whatg is causing this. my car runs rich a idel. it will almost burn your eyes.
