Yeah, exhaust replacement is a very common upgrade for various reasons; performace and economy OR both. It's not only size of tubing, but also type of bends, and muffler designs that affect thr performance of an exhaust system. There are various companies who offer systems for your truck.
I've attached links to a few such companies.

But I would suggest that you do some research and compare prices, economy numbers, performance numbers and longevity the different materials that are use to make. |
