Aeroflow's 5000 series mufflers are the perfect choice for today's street driven high horsepower muscle cars where both flow for maximum performance and decibel reduction are critical. Manufactured from durable 16 gauge TIG welded aluminised steel and coated in a high temp silver finish, Aeroflow's 5000 series mufflers are a chambered design for a consistent sound that won't change over time. When used as part of an appropriate exhaust system they offer a throaty exhaust sound on acceleration and quiet operation at idle and cruising speeds. These mufflers are available in 3 configurations (Centre/Centre, Offset/Centre and Offset/Offset) with inlet/outlet sizes in both 2-1/2"" and 3"". Will fit many applications, perfect for the single system or classic muscle car dual exhaust.
