Show original supplier description
Its compact, straight-through flow design with 3.50-inch center inlet and outlet is ideal for high-flow applications. The muffler's chambered internal design enhances sound output without internal packing, ensuring a consistent tone over time. Constructed from heavy-gauge 409 stainless steel, this muffler offers robust durability and high heat tolerance, featuring a raw metal finish. Its fully welded and rust-resistant housing is built to withstand extreme driving conditions. The overall length is 12 inches, with a 6 x 5-inch body size, making it suitable for tight spaces. Installation is a weld-on type, requiring professional alignment and welding for optimal results, though it is adaptable for custom exhaust builds and modifications.
