Thanks! And I agree that a tune will help since the stock tune is with a GM air intake and cast exhaust manifolds vs. my custom intake and 1-7/8" long tube headers. For now it'll do just fine and the surging isn't bothersome, just very noticeable. I'm guessing it might get a little old after the initial euphoria wears off just like people comment on the FFR sidepipes. Amazing to hear the loud raspiness at first but after a few thousand miles the nostalgia wears thin with some people.
Time will tell I guess.
