2014-2017 Chevy SS / Holden LS3 2" Primary Header & Exhaust Manifold System

FITMENT ON THE HEADERS TO THE VEHICLE "MAY NEED" MODIFICATIONS TO THE RUNNERS TO CLEAR THE STEERING SHAFT. 

This complete header is MSRP'd at $2000.  Due to the possibility of needing minor modifications to fit, we are lowering to the price above for the inconveniences.  So far most fit well, only a set of 2 sold requires slight modifications.   You save over $1k plus!.. Clamps, Wiring Harness and Gaskets are included.

Circuit Werks latest for the LS3 powered Chevy SS, they quickly filled the void created when the Pontiac G8 was eliminated. With over 400 HP to start with, we knew we could produce considerably gains with our header and exhaust system.  With tuning and a quality Cold Air Intake you can see up to 50 WHP. Primary sizes are 1-7/8" with 3" collectors followed by a 3" X-pipe system that extends back to the factory (or aftermarket) axle back mufflers.  With stock exhaust, customers are seeing 30+ hp gain.  With intake and a tune, you can see 50+ hp gain.
