Exhaust Pipe Size on Convertible

Short answer: On a convertible the limiter is the pan brace — getting anything bigger than 2.25″ past it (sharing space with the transmission tailshaft and driveshaft) is tough, though some have fit 2.5″ with creative bending/ovalizing. For ~400 hp from a 350, 2.5″ won’t be a plug.
