Product ownership: A year or longer
Purchased from: Pypes Performance Exhaust
Several years ago (6-7 now), I had a stock TBSS. LS2, auto, 4.10s, AWD, 2006 1LT model. It was a ton of fun but I wanted louder. I had a local shop install the M-80 that I bought from this site. They also removed the resonator and welded on the stock tip. The infamous Youtube video is still out there and has been one of the most popular exhaust clip videos for this vehicle since I posted it.
The sound at idle was tough. It was deep, very deep. Deep especially for an LS-powered vehicle. At part throttle, it came alive. At WOT, it woke the dead. It was the best mod I did to it before the vehicle was totally rebuilt.
After a forged bottom end, cam, headers, etc, the M-80 was just too much. I had a cutout before the M-80 and it made zero difference in noise. There are videos of that, too. The tone changed but volume stayed the same, haha! I ended up finding the biggest, quietest muffler I could find that would fit. The M-80 is still alive and well and going into a 70's K10 pickup.
The Pypes Exhaust logo on the building at Maple Grove always intrigued me. I listened to muscle car exhaust clips with the Violators and fell in love. Now all my toys have the complete systems.
You won't be sorry with their products!
