    Hogan Performance W-Body 3" Stainless Steel Downpipe with Off-Road Pipe: 3800 Performance

    Just get a 3" bolt in catless downpipe.

    Up to you if you want stainless or mild steel.

    This will eliminate your cat and bolt right in.

    I agree... or find a local who can weld... and slip him so cash to hook you up. Take him your stock dp...then cut the cat...and put a straight pipe.
