I love the tone, but I get a lot of backfiring now. I didn't think removing 2 of 4 cats and the resonator would cause this.
Anyone else see this before?
are you sure its backfiring and not just the "gurgling and popping"? I have full catless and I get lots of gurgling and popping but they only time i ever get a hint of backfire is when i am wot at low rpm and then shift gears before 3500 or so
