Is yours a Yukon XL SLE/SLT or is it a Denali? Only the Denali has the 3.5" exhaust with the 6.2L. The 5.3L trucks have a smaller diameter exhaust.i recently bought a 2013 gmc yukon xl and i want a deeper and a bit louder exaust. I know very little about exaust and i was just wonder what the go to is usally for these.
100% I love the sound of our XL Denali's. The cammed 2012 even more so.I personally think the Denali XL factory exhaust has the best rumble inside the cab, without the drone of most aftermarket setups. 2 more feet of pipe really makes a difference between that one and the standard yukon.
The 6.2L exhaust is very efficient... If you want 'more' sound, then maybe you
could remove the resonator that's all the way at the end near the outlet. It's there
to quiet the resonance when the AFM/DOD is activated
