This Borla cat-back exhaust system for the 1997-2004 Chevrolet Corvette C5 and C5 Z06 5.7L V8 is a very aggressive straight-pipe design that eliminates the mufflers and finishes with dual 4 inch round polished T-304 stainless steel tips on each side. It produces an extremely loud, race-inspired exhaust note drawn from Borla's experience with C5-R Le Mans and privateer Corvette programs. Borla uses patented, race-proven straight-through technology with premium T-304 austenitic stainless steel, superior to 409 or aluminized steel, for free-flowing performance and durability with an easy bolt-on installation, and backs its street products with a written Million-Mile Warranty.
