OK well I have a completely catless setup with a SSQV and I have no bucking, no backfiring and no black buildup on my back bumper. That is just your experience with the RFL BOV. ANd this is just my experience with my SSQV BOV. That being said the only thing to do is try a BOV if you want and if you experience issues, go back to stock.
