The Borla S‑Type axle‑back system for 1984–1991 Chevrolet Corvette (C4) 5.7L V8 converts the stock 2.25" axle‑back to a 2.5" system and delivers the classic S‑Type tone with minimal interior drone. Built from T‑304 stainless steel with mandrel bends and polished rectangular tips, the system increases exhaust flow and appearance while requiring a mid‑pipe outlet expansion for complete installation.
