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 firstname.lastname@example.org if you have any questions.
