    GM8424 is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Works great! Surprising how much it helped. I have a 4" exhaust on my 04 GMC LLY, it was loud enough I had to shut it off to hear or be heard at a drive thru. No more! This actually quieted it down, until I hit the throttle and then it sounds so good! Helped my mileage noticeably as well as the performance. Well worth the money. Installation wasn't too bad. Fit and finish are very good. I have a 50 hp/ 100 tq tune that I now realize I wasn't getting the full benefit of. Now for the intake elbow and a cold air kit.....
