Primaries Size
Regular price $429.99
  • 14 inch average primary length
  • Near equal length primaries
  • 3/8 inch flanges prevent warping and leakage
  • 1.5" primaries maximize NA setups
  • Larger 1.75" primaries maximize supercharged setups
  • O2 extension harness included
  • Grade 9 downpipe bolts included
  • Stainless steel downpipe

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.

Primary Size: 1.5" is recommended for NA applications (no boost). 1.75" is recommended for boosted applications. The 1.5" primary will have more torque than the higher flowing 1.75" header, it will also work great in boosted applications.

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.

Great quality and fitment

Ordered for my 06 SS, arrived in three days. Bolted up. I mean actually bolted up to my factory catback exhaust. Great attention to detail I had to hammer the old exhaust studs out of the factory exhaust ******. The supplied bolts fit in the existing holes did not need to use my drill. Came with everything needed bolts, gasket and extended o2 harness. Would buy again. Highly recommend.

Love it!

Great product. Good design and construction. Bolted right in with very little issues. Would've been 5 stars had the exhaust gasket been included. It's like 12 bucks, just put one in the box for goodness sake. :-D
