Dunno about that one. I had no CAT in the Excursion.

The earlier Excursions didn't have cats. The computer controls of the system kept the exhaust clean enough to get by without one.

I have a 2000. Don't know when Ford started adding cats.

They added a cat with the 6.0 in 2003. I have a Banks 4" turbo back system with a 3.5" down pipe, the fit and sound is great. I need to find someone near me to exchange a stock system for my Banks before I give this back to Ford. My wife threw my stock system away a couple years ago because she was tired of looking at it, great huh?

I will probably put a Banks on my next truck, unfortunately all the systems for the Dmax's are "down pipe back" and not turbo back so you have to spend another $200 on a 3" down pipe!

Well this will mess things up. Mine does not have a cat because it was a oregon vehicle and they did not req it. The only thing I can come up with was mine was installed a local shop noted for doing Outstanding work. Maybe they know something...Just a thought

So who was the "outstanding" shop. I have seen some of the "outstanding work" locally on a rack at a friends shop.... and some of it's not all the great. I wonder what will happen with us when CA finally figures out how to smog the Diesels eh? Does your rig at least have a CA Emissions legal sticker under the hood?

There was only one guy in town that I used for all my exhaust work, and it sounds like he is hanging up his exhaust installation hat
