ARH 2" Long Tube Header System – Product Details

• One-piece long tube header design with optimized routing for the C7 chassis
• Merge collectors with scavenger spikes for strong exhaust scavenging
• Includes an X-pipe midsection and connection pipes that run to the rear axle exhaust connection point
• Designed to mate to stock or aftermarket axle-back exhaust systems
• Built in the USA and backed by a lifetime warranty

Benefits

• Maximum airflow capability compared to smaller primary header options
• More aggressive exhaust character under throttle and wide-open acceleration
• Complete flow path: headers + X-pipe + connection pipes to the axle-back interface
• Premium stainless construction designed for repeated heat cycles

What to Expect After Installation
Expect a louder cold start, a deeper and sharper tone under load, and a more responsive feel as the exhaust path opens up. The 2" primary option is typically chosen when the goal is airflow capacity for aggressive street/track combinations.

What Customers Say

• Premium build quality and clean welds right out of the box
• A deeper, more aggressive sound that’s most noticeable under load
• Best results when the exhaust system is planned as a full flow path (headers to axle-back)
• Catted vs catless usually comes down to local rules, odor preference, and how aggressive the setup needs to be
