Eliminating the cat
The TT models have 3 cats, one main cat, and 2 pre-cats that are right after the turbos. There are 3 O2 sensors on the turbo models, one by the main cat and 2 at the precats.
Is it possible to remove the2 cat's at the turbo's without screwing up how the o2 sensor reads? Is this a bolt on product or is it a custom fabrication project? I'm askingthese questionsabout the cat's because the Dodge Ram trucks(which I am a owner of a 99 Ram)are infamous for clogged up cats which in turn burn a valve. I really don't want this to happen on my stealth and wondering the best way to delete all of the cats with still making the o2 sensors work correctly. I also know the after cat o2 sensors monitor cat efficency, and pre o2's monitor air/fuel mixture.
Thanks, Jeff

There are two ways to do that, the cheap way or the PITA way. If you can unbolt your downpipe and cat, use some sort of tools/drills to "gut" the them. You can do the pre-cats while they're still on the car, its messy, wear goggles and a dust mask. That's the cheap way, the $$ way is to buy pre cat eliminators and a testpipe.
Of course doing this will cause you to fail emissions testing. I don't know if it will cause a CEL on 94+
