Have you noticed any popping or backfiring through the intake or exhaust with the stage 1? I have heard that might be a problem. All I have done to mine so far is knock out the two plugs in the left muffler and the back plug in the right and drilled a half-inch hole in the front plug. The helped it breath better and evened out the backpressure.
