The first design 1970 exhaust tip was used through VIN # 14,000.
From around VIN # 14,001 through 1971 VIN # 16,000, Corvette could have either 1st or 2nd design style tips, possibly 1 of each. From 1971 VIN # 16,000 forward, all cars had the welded seam, 2nd design tips.
Metal finishing is done to best reflect the surface G.M. specified in the early 1970's. Chrome plating finish replicates that used by G.M. during production, not the high gloss used on any reproduction parts.
