I wanted to buy a Downpipe, or do the U-Bend Delete as a final precaution before I swap my Supercharger Pulley, but I am kind of confused as to what I would need to stretch for as price.

I looked at the Downpipe by ZZP (ZZ Performance)
and I am kind of lost and intimidated...

I would need, now correct me if I am wrong, a 3" Bolt-in/Weld-in w/cat, as I still need to pass emissions. What comes with this? Is this from the engine down, including the catalytic converter, and then goes to the joint where the resonator is, or what?

And then I won't need the bung for offroad or 04+ because I have 99 and want to keep it street legal.

And finally, weld in vs. bolt on. What would it be welded to? The joint where the two are bolted together at the moment or what?


I know it is a lot, but I appreciate it!

Thanks.
