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 high flow catalytic converters are EPA certified. If your state requires CARB compliance, these do not meet that CARB standard. Please contact firstname.lastname@example.org if you have any questions.
