    Getting pipes/muffler tomorrow & wanted to know if you guys have had any issues with removing the rear cats, just before the "Y"? Gas mileage decrease? Warrenty issue? Any check engine light......etc?

    It wont cause your check engine light to come on, that will only happen if you pull the primary cats. The computer only monitors the primary cats.

    URD makes a y-pipe that replaces the rear CATs. You will have to put two bungs in though for the rear O2 sensors or you will get CEL's. The one pictured below is for pre-runners.

    No issues. Your exhaust will get a bit louder, so if you still have the stock exhaust you'll end up changing that also because it won't sound that great with the stock muffler.
