C6 Corvette ZR1 American Racing Headers 2 inch (2009-2013)

C6 Corvette ZR1 American Racing Headers 2" Long Tube Header System (2009–2013)

For 2009–2013 C6 Corvette ZR1 owners, the American Racing Headers (ARH) 2" Long Tube Header System upgrades the exhaust flow path from the factory manifolds through the X-pipe mid-section and connects at the rear-axle junction so it can mate to your axle-back. It’s built to improve exhaust efficiency on the supercharged LS9, sharpen throttle response, and deliver a harder, more aggressive tone under load.

Choose Your Configuration

• With Cats (300-cell): C6 Corvette ZR1 2" x 3" long tube header system with catted X-pipe mid-section
• No Cats (catless): C6 Corvette ZR1 2" x 3" long tube header system with non-catted X-pipe mid-section

Key Features

• 2" primary tubes feeding 3" collectors for high-flow LS9 builds
• Merge collectors with scavenger spikes to improve exhaust velocity and cylinder scavenging
• 3/8" laser-cut flanges designed for a warp-free, leak-resistant seal
• 304 stainless steel construction with TIG-welded inlets and optimized routing
• X-pipe mid-section included (catted or non-catted depending on configuration)
• Built in the USA and backed by a lifetime warranty

Performance & Sound Expectations

• Power delivery: stronger pull through the mid-range and improved top-end breathing on the LS9
• Throttle feel: quicker response, especially when rolling into boost
• Sound: noticeably louder and sharper under load with a more aggressive character at wide-open throttle

What Customers Say

• “The fit and weld quality are exactly what you expect from a premium header system.”
• “Noticeably stronger pull in the mid-range and a much more aggressive sound under boost.”
• “Everything lined up cleanly at the rear-axle connection—worth doing once and doing right.”

For a C6 Corvette ZR1 that’s driven hard, the ARH 2" long tube header system is a top-tier way to improve flow, sound, and overall exhaust efficiency on the LS9—while keeping the rest of your build flexible for the axle-back you want to run.
