Not much, maybe talking 8-10hp at most. I had LT headers and when I added the catback and had another dyno, it was small, but it was there. The L99 exhaust does have some 'flow' issues going on, not sure if it's to help with the AFM or not. For me, the sound just wasn't there with the stock exhaust after adding the LT headers. It was better, but not what it 'should' be. I later added the Solo Cat back and DMH cutouts and I am very satisfied.
