C6 Corvette Hooker BlackHeart Axle Back Exhaust - LS2 (2005–2007)
For 2005–2007 C6 Corvette Base owners running the 6.0L LS2, the Hooker BlackHeart 70401312-RHKR is a 3-inch axle back exhaust built for drivers who want a stronger rear exhaust section than stock without stepping into a straight-pipe setup.
This system uses high-flow straight-through mufflers and Helmholtz resonators, so it is a smart fit for LS2 owners who want a deeper, more aggressive exhaust note with better cruising manners than a no-muffler axle back.
