Great system

Good deep throaty sound, not raspy like magnaflow. Not too loud, perfect for that agressive but not excessive sound. The hanger that comes with the system is junk but $2.35 at the auto parts store is a small price to pay for a better clamp.

Sounds awesome!

2010 GMC Sierra . Fit perfect. EASY install. Did not weld. Used two standard U-clamps instead. The clamp they provide did not seem tight enough, Outside truck sounds great. Be prepared for considerable interior cab resonance. Took a sec to get used to it.
