Got my pipes on last week and LOVE them! Look GREAT and sound even better. My question is the backfiring while throttle down. It happens some times not all the time. Is this normal?
Thanks alot.

Its probably a little lean at closed throttle, its very common with drag style pipes. If you are running a PCIII try modifying your map by adding fuel at "0" throttle from 1500 rpm up to redline. Start with a number like 10 and if that does not work go up to 20, this fixed my backfiring and a few others I know of. If you do not have the PCIII I am not sure what to do, the PCIII is the only one I have experience with.
