Yukon Denali - Dual 10 Series Flowmasters

Yukon Denali, 6.0 liter with true dual Exhaust. Mufflers (or sounds like lack thereof) are dual 10 series (one chamber) race mufflers. As always videos don't do this setup justice. It really nasty at idle and when you really get onto it. I will try to get a video of drive-by's and when it shifts out of first, it is like a Harley (blatty)

I put a Super40 Flowmaster on my 2003 Yukon Denali 6.0L. It's not as loud as my Dodge Ram Hemi but it does sound sweet!
