It bolts in pretty easily as long as you aren't fighting with rusty bolts, IIRC you need a 13 or 14mm socket up front and a 15 in the back, two bolts come off on both ends, stock downpipe comes right off, put some gasket sealant on both ends, bolt the new one in, good to go.

    The front bolts are in an awkward position though, it's a PITA to get out if you're dealing with stuck bolts/don't have a good extension (like I was - a fifteen minute job turned into three hours).

    As far as tuning out the P0140 code that the car -will- throw if you have a catless, just come to the meet - I'm getting mine tuned out on that occasion, too. IIRC dsmuts was charging $20-40 per tune, correct me if I'm wrong?

    Nope. I never did manage to pull the rear O2 sensor out of the stock downpipe, I just disconnected it at the wiring harness. I then pushed the wire back up where it came from (there's a covered area you'll see where the wire runs forward from the rear O2's location).

    The whole contraption is in my closet along with all the other car-related supplies, until I get around to scrapping it. Who knows, maybe with some PB blaster, a couple hits of PCP, and a psycho scream from me, I'll manage to yank that guy loose and sell it separately some day.

    I got mine from W-Body, it was actually cheaper. Get the aluminized, because at the age of most GP's it will outlast the car anyway.

    Not a huge deal, just don't stand there whiffing it all day. (I think.)

    Personally, I let people think I have an exhaust leak somewhere/something is broken. Helps contribute to a sleeper image.

    Just get a walker replacement downpipe, they have a better quality converter than the cheap ass high flows that ZZP uses.

    06-07 can't be tuned as said above, so its better to just get a quality cat.

    Going catless will just make another issue.
