Unfortunately the SLP is for the standard Denali 6.2, not the Yukon.
If I do the coustom route, what muffler do you guys suggest? Dont want to hear a bunch of noise in the cabin. Mainly just want the dual exhaust look. Slkghtly louder exhaust is fine, but just want to go crazy since its the family truck.
Also, just to confirm, is the 2011 Yukon Denali XL 6.2L have 3" or 3.5" exhaust piping?
Thanks again everyone for all the input!!!
