This is our most affordable header and downpipe package. It installs in under 2 hours. Freeing up the flow of your exhaust allows you to run smaller pulleys safely. Look for gains between 10 and 25 horsepower, depending on your mod level. The downpipe has a 2.5" exit so it connects to a stock or 2.5" aftermarket catback. This header/downpipe setup must remain as a combo and is not compatible with the OEM manifold and/or downpipe.

How to order your header/downpipe package:

Transmission: Automatic or Manual transmission. This determines the length of the downpipe.

Extra O2 bung: Each downpipe comes with a bung for your rear o2 sensor, however If you would like a second o2 bung for a wideband o2 sensor gauge, then select the "Extra O2 bung for aftermarket wideband gauge" option.

 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.

Headers were a pain to install but worth installing since I had a cracked manifold, doesn’t come with a gasket

Header and down pipe awesome

They sound and perform great had a little issue with the stock header bolts because they are more round just shaved the bolts down a lil and they worked just fine

2.5 Mid-length and Downpipe

Looks great and sounds good. Only issue was I had to use a open-end wrench across top of header because it was to tight to fit socket. Bolt perfect to stock catback until I can get it upgraded.
