Product Description

The Magnaflow 12229 stainless steel performance muffler is engineered for use in custom and performance exhaust systems where improved flow and signature Magnaflow tone are desired. Its 14" x 5" x 8" oval body and straight-through perforated core help minimize backpressure and enhance exhaust dynamics compared to many restrictive stock mufflers.
