I installed a Vance and Hines CS One exhaust, two brothers cat eliminator, and a Dynojet PCV on my 09 R1amd it's backfiring alot with flames coming out of both pipes. I've tried 3 different maps (2 suggested by a dynojet rep) and it's still lighting up the pipes like crazy.
Does anyone have any suggestions for this and could this harm my engine?
