Simply the best.

By Walt G on January 8, 2022

For one second. I thought I had made a mistake. After letting my 1999 GMC Sierra 4.8 warm up. I was sold. This sounds as good or better than most muscle cars. All I did was add the Super 40 to my 2.5 pipe. I also noticed a slight gain in power. I was going to install a radio but not now. 2000 rpm is the sweet spot. Vrrrrrrm. Vrrrrm. I have it dump out under the rear tires. Absolutely no cabin drone. I can listen to music, talk or get on it. Perfect. Going to add headers next.
