How to order your header/downpipe package:

Transmission: Please select manual or automatic transmission, this determines the proper length of the downpipe.

Catback Flange: This determines what exit flange is installed on the downpipe. If you select "Stock/2.5" then it will come with a 2 1/2" exit flange that will bolt up to the stock catback or most 2 1/2" catback exhausts. If you select "ZZP 3" then it will bolt up to our 3" catback exhaust or most aftermarket 3" catbacks. We do not guaranty fitment on other brand catback exhausts.

Wideband Bung: All long tube header packages come with a bung for a wideband O2 sensor. If you will not be using this extra bung you'll want to purchase a bung plug. 

*This header will fit on a 2.2L but can have a clearance issue with a coolant line on the firewall. An easy fix would be to remove the 90 degree turn and connect the hose straight to clear the header.

Our downpipes come with a high flow catalytic converter that is 48 state legal. Our catalytic converters will not pass California or New York state emissions. Please contact customerservice@zzperformance.com if you have any questions.

*06+ Cobalt 2.4L will require a style B O2 extension harness.
