The ZR1 is already a beast—but stock restrictions choke its true potential. Our High-Flow Catalytic Exhaust system is engineered to free the fury. Designed with premium 200-cell HJS tri-metallic sport cats, this system dramatically improves exhaust flow, turbo spool, and throttle response—without compromising emissions compliance*.
Crafted from aerospace-grade T304L stainless steel and TIG welded for maximum durability, this upgrade delivers a deeper, more aggressive tone while shaving weight and unlocking real horsepower gains. Expect quicker turbo response, a ferocious growl, and dyno-proven performance increases across the RPM range.
Whether you’re chasing numbers or just want your ZR1 to sound as wild as it looks, this is the upgrade it’s been begging for.
