Mandrel bent and stainless is a lot of hype. You will never notice the "loss in flow" and stainless usually contacts mild steel somewhere. The current aluminized custom built local system I have was done in '04 and the truck runs as good and sounds as good as can be. My camper hauler got a system in '89 and was still on it in '04 when I stopped running it. Isn't 15 years long enough to satisfy?

It's been a while but I want to do something different this summer with exhaust. I used Tire Mart in Frederick, MD last time. I need to check who is doing exhaust now. There are exhaust shops all over. There is a guy in the area that does custom mandrel bent systems, but very very expensive. I have a Bartens bumper, a swing down spare carrier, and hitch bracing. I had them dump it out the rear quarter under the bumper
