Default Off road Y-Pipe for '04 5.3L crew cab

Where do I get an Off road Y-Pipe? I want to get rid of my cats and want a "bolt-up" kit.

I don't think anyone makes a bolt up off road pipe. I know magnaflow makes a pipe with high flow cats.

List price is $344 but you should be able to pick one up for around $250.

I bought two sections of stainless pipe, chopped my cats off and welded the sections in a few weeks ago for about $60.00 and a bottle of booze for a buddy.

there is a huge amount of flow restriction in the stock y pipe I dont care what anyone says. You will notice a big difference even with the stock manifolds still on.
