wtb stock downpipe

[sonic hotness]

Hi I am looking to purchase a stock turbo downpipe. Or zzp:/

I'm probably reading this wrong, but isn't the downpipe a (in many places illegal) aftermarket mod that's put in to replace the second catalytic converter? If that's right, then by definition there is no stock one.

Or are you looking for that awful accordion thing that connects the air box to the manifold? Do you mean to chop out just the part that holds the MAF?

I made a substitute intake pipe from Spectre parts for just a few dollars and five minutes work at Advance Auto, if it's literally just the tube you want, that would probably be the simplest way. The MAF fitting sits in the top half of the SAB, and good luck getting anyone to give up one of those. They are pretty cheap from online supply houses though.

The OEM downpipe holds the first cat, right off the turbo. The after market piece would be illegal in most markets since there is no cat.

He's looking for the catted down pipe off the turbo that connects to the mid pipe or the ZZP O2 housing. ZZP calls the DP an O2 housing.

what they said. connects to the turbo with a v-band clamp.

good luck OP.

You can do anything with the right tools

Is the idea to pass inspections with what looks like a stock cat while actually having the open flow of a catless down pipe? Like a sleeper down pipe?

that would be the upside I see, plus it's free if you just use your stock one.

Hmmmmm...I wonder if the shape of the empty cat would have a positive or negative effect on air flow vs. a purpose-built catless down pipe?
