Trying to find correct X-Pipe for 2013 ZR-1, is this part/casting number correct for 2013 Z? When did they start putting cats on ZR1 x pipes?



GM20968756

Extra cats are on the 12 and 13 models. If you're buying go with the Corsa 14331 x-pipe with no cats. Your console won't get nearly as hot plus a few hp and a little better sound.

^ This. Unless of course you're returning a car to stock to sell.

Thanks for the replys. Is GM20968756 a part number as I cannot confirm if for 2013 ZR1?

Here's what I come up with: https://www.gmpartsdirect.com/oem-pa...YtMmwtdjgtZ2Fz

I know the illustration doesn't show cats on the pipe...but you can clearly see it only fits 12/13 models (and its regularly priced at ~$830, which would suggest cats as well).

Provette where do you live? I have an 11 that previous owner put back to stock and has a 12/13 x pipe with cats id be happy to sell

Interesting. Would that Corsa 14331 be what I could use on a 2012 Z06 with 4 cats and still be able to retain the rest of my OE exhaust? (OE exhaust manifolds and mufflers?)

Never mind, found my answer. I did not know that this existed, good to know!

Yep...if you don't have one, you need one. Get rid of those silly two extra cats.

BigVette427

You don't pop a CEL with the two other cats removed? No tune is otherwise then required?

MTPZ06

Correct...nothing required as those cats are after the O2 sensors.

I sent you a PM..

I really like this idea for my 2013 , are there any choices better or worse for fitment or quality. I'm sure Corsa is good but are there others out there?

I haven't found another one yet, and the Corsa can be had for like $415 through the right vendor. B&B makes an x-pipe but it's only for 2009-11 models. I asked them and they said it will not fit 12-13s (I have a '13).

MTPZ06

Corsa is the only mid-pipe I've seen to eliminate the aft cats on 12/13 models.

INTRCUL

Does anyone know what the Corsa catless pipe weighs? I think the OEM pipe with cats is around 40lbs and the titanium x-pipe from Akrapovic that only fits the 09-11 models only weighs something like 9 or 11 lbs.

MTPZ06

Good guess would be ~20lbs. I think the OE catless "H" mid-pipe from my '09 was 19-20 lbs.

I had the Corsa on my 13 and loved it! Great sound and felt a little snappier. Great investment.

I brake for nothing

Can you still get the Titanium Akropovic stuff ?

MTPZ06

Nope...second-hand only for our cars.
