I had to replace the cat on my '00 Dak at 140K (I've always run 10-30 Val in the engine)

I'm in Comm-i-fornia, land of smog tests. The replacement cat was listed at $580 I got a friendly deal from a board member (thanks Troy!)Still a butt load of money!

You don't have a location listed but if your truck has to get a state sniff, I wouldn't do ANYTING that might accelerate the wear on the emissions system. Your truck do what you will, it certainly won't harm the engine.

Not the green police, but having been down that road, just sharing what might lie head if you chose. You might think an aftermarket cat will get you by? UM... Not in Cal. I fell out of "gross polluter" status but couldn't pass to register with an aftermarket... It had to be OEM to make it on the sniff.

EDIT: on my '00 warranty on emmissions was 8-80 not sure it '01 is different?
