Description

C6 Corvette Hooker BlackHeart Axle Back Exhaust – LS2

For C6 Corvette owners looking for an NPP-compatible rear exhaust upgrade, the Hooker BlackHeart 70401313-RHKR is a 3-inch axle back system built for a deeper idle tone, stronger sound under throttle, and a cleaner polished-tip finish than the factory rear section.

This system is a smart fit for drivers who want to keep the factory dual-mode valve function while stepping up to a freer-flowing rear exhaust. It gives the car a mellower, throatier tone when the valves stay closed and a more aggressive edge when they open.
