2008 GMC Denali 6.2 – Flowmaster True Dual Exhaust-By Rich’s

We start from the cats back carefully building a custom true dual exhaust that is balanced and equalized allowing for maximum flow without the drone in the interior.
Using our Flowmaster crossflow muffler to further balance and equalize the exhaust pulses but still allowing the truck to have a deep throaty tone to the rear of the truck.
