Product Description

The Vibrant Performance 1129 3" x 7" Oval Muffler is a universal exhaust component engineered for custom performance exhaust builds. Its true straight-through internal design and dense sound-absorbing packing help minimize backpressure while delivering a rich, deep exhaust tone. Constructed from durable 304 stainless steel with a polished finish, this muffler resists corrosion and integrates smoothly into fabricated exhaust systems on cars and trucks.

With 3" inlet and outlet diameters, the 1129 muffler fits a wide range of performance exhaust setups, including naturally aspirated and forced induction engines. The 7" oval body shape provides efficient internal packing and allows enthusiasts to tune their exhaust tone while maintaining strong flow characteristics. Ideal for custom cat-back, turbo-back, or free-flow exhaust designs where performance and sound quality matter.
