Nice muffler but still too noisy on my car (without catalyst).
Fits 2 on a Chevelle 69 with headers. (Headers, then short pipes, mufflers, no exhaust pipes, dual exhaust). Still too loud for me. Maybe good for cars with catalytic converters, or maybe good with full exhaust including tailpipes. Good price.
Pros
CORROSION RESISTANT -- Aluminized steel construction and internal drainage help reduce corrosion
