If you have a Federal Emissions LB7, not a Cali truck, you cant find the exhaust system you are looking for because you don't have a cat.

I have run muffler systems on both my trucks, and like not having the excess noise or drone, just my 2 cents...

Pepboys, Advance Auto, Autozone, NAPA, O'Reilly's, Western Auto, Wal-Mart etc. Aunt Jeff did mine, I'll have to ask her where she got it.

Unless you special ordered it with a cat, or you have a California emissions model, you do not have a converter. You'll need a turbo back (Downpipe back) exhaust. Look at the vendor section here and contact one of them

These guys will take good care of you. They have many systems listed for cat backs.
