Does anyone know if someone makes a catless Y-pipe for the 4.2? I guess I culd have it custom fabricated...but someone got to be selling these for off-road.

 

^ No they do not. Yes you culd have it fabricated, but why?

 

Agreed

No one wants to hear a cat-less 4.2.

 

They don't sound too bad with a decent muffler. Trying to get all the mileage and perf out of that v6 for towing a boat. If you're telling me that removing the CATs will not help it breath better or improve mileage....I'll leave it alone.

 

By itself, it won't net anything. There are much better choices out there for improved towing performance, like a programmer or rear end gears.
