Offroad Y-pipe for stock manifolds

I'm looking around the internet see if there's a direct fit offroad y-pipe that would work for me. I want to reuse my stock manifolds. Anyone know of something that would work for me?

Thanks
Greg

Jegs FTW.

Fit great on my 2006 Sierra. Prepare for some rasp or drone if you don't have a resonator before an aftermarket muffler.

chop out the converters and weld in a piece of pipe. i think the manifold it self is the restriction at stock levels...more so than the converters anyways.
