If your looking for an aggressive sounding system this is the one to go with.
Here is some info for the redesigned system -
Give your 1997-2004 C5 Corvette a bark to match its bite with SLP's "Loud Mouth" exhaust system. Constructed from mandrel-bent 304 stainless steel, this bolt-on system offers up to a 15-hp gain and a 20-lb. weight savings over stock. It features 2.5" over-axle pipes and 2.25" electro-polished tailpipes terminating in 4.25" rolled tips. Use with SLP's X-Pipe/Resonator Assembly (part# 30064) for a mellower, less aggressive tone with minimal flow restriction. Detailed instructions, a limited lifetime warranty, and all hardware necessary for installation are included.
