C5 Corvette Hooker BlackHeart Axle Back Exhaust

Description

C5 Corvette Hooker BlackHeart Axle Back Exhaust 70401343-RHKR (1997–2004)

For 1997–2004 C5 Corvette owners running the 5.7L LS1 or LS6, the Hooker BlackHeart 70401343-RHKR is a 3-inch axle back exhaust built for drivers who want a stronger rear exhaust section than stock without jumping all the way to a no-muffler setup.

This system uses high-flow straight-through mufflers, so it is a smart fit for C5 owners who want a deeper, more aggressive sound with better control than a straight-pipe-style axle back. It also adds the cleaner look of polished 4-inch quad tips and a lighter rear section than OE.
