I've done an extensive search and haven't been able to come up with any dual exhaust set ups for the Envoy Denali. I'm thinking of cutting a matching notch in the rear valance on the drivers side and doing split rear tips with a Borla muffler. I've had MagnaFlow on the 5.3L on my Sierra but want something a little different.
