Replacement Dual Exhaust on 1968 Convertible
Short answer: Members have installed the Flowmaster 2.5″ dual kit with crossover (from Summit and others) on a 1968 convertible. The 40-series mufflers fit, and the kit includes clamps and mounts that bolt to stock locations — but it comes with header flanges, so you’ll need a muffler shop to weld up the pipes from the exhaust manifolds (cheap reducers get you there). It sounds great: quiet at idle, aggressive when you get on it.
