Well, before having the cutouts put in, my car had a great sound through a full exhaust. But with the cutouts, I can't get everything to seal and it constantly sounds like a bad exhaust leak. As for the stage 4 cams, I was a little weary about putting those in because I drive my car daily and I didn't want it to jerk at low speeds. But, the place that tuned my car did an amazing job tuning it, and it doesn't jerk at all. Therefore, I love them. I put in Comp Cams P.N. 106460 if you are looking into getting cams. You won't regret it unless you drive your car for gas mileage!
