In my neck of the woods they are sold for $25,000 (actually that is what the fine costs if you get caught without the cats)...

You aren't going to lose much sound or power if you go with high flow cats, might want to keep that in mind if you have gestapo emmisions like we have.

Actually he's already there. You aren't even allowed to "move" the cats in the Federal regulation.........

yes, cel will be on unless you had a tune already and it has turn off the rear o2's. see my sig.

yes, catless will make your exhaust a little louder then what you have and gain some hp/tq too. you do have to figure out how to pass emission when that time does comes.

where I am at, they do a visual inspection only. I took the stock cats and cut them in half at the factory weld. We cut a section of 2.5" pipe that fit perfectly through them and welded them in. Then we rewelded the factory welds on the cat. The result is a complete factory look without cats. those censors can be tuned out by your tuner although they can retain the factory location. the exhaust got a lot louder.

I've got the KOOKS offroad x-pipe and the odor is atrocious. I would go back to high flow cats but my tuner is 400 miles away.
