Great exhaust! This is installed on my 2004 Tahoe Z71. The tip lines up perfectly with the 'cutout' on the rear fender/bumper area. Very mellow while cruising, idling, etc. Nice and tolerable on the interstate. No drone in the cabin. Step on the gas a little bit more and the exhaust notes are beautiful. At WOT, it definitely makes some good noises.
