Flowmaster 40 on the 5.3 Vortec

[aanold]

I’ve got an ‘05 Sierra as well as an ‘05 Tahoe. I made this video of the Flowmaster in the Sierra and plan to mod the Tahoe the same way.

I made this video of the Sierra thinking it may help some guys decide which muffler they’d like to go with. Let me know what you guys think.

I have a Flowmaster on my o4 Z71 sound so good!
