Stock Duramax exhausts are the easy way. I bought 3 of them and never paid more than like 50 bucks for a complete one turbo back that has no mileage on it.

They actually sound pretty good surprisingly on gas truck. A buddy put one on his LQ9 swapped extended cab half ton....... even with the stock 5.3 manifolds and catted y pipe the truck was a lot deeper at idle and barked pretty good when you were on the throttle...... nothing like a 6 liter HD's exhaust sound at all. I need to quit being lazy and swap one of mine onto some of my trucks lol.

 

we do tons of diesel stuf at work but usually 07+ so those exhaust wont work.
