Show original supplier description
The K2 Industries Universal Round Exhaust Muffler is engineered for custom exhaust builds and universal applications, offering a straight-through design for optimal flow. Its 2.5-inch inlet diameter is intended to directly connect with most 2.5-inch exhaust piping, while the 4.0-inch polished tip provides a sleek aesthetic that complements various aftermarket exhaust systems. Constructed from durable stainless steel, this muffler is built to endure high temperatures and resist corrosion, ensuring longevity. With an overall length of 18.5 inches, it is designed to be compact enough for tight exhaust routing without causing excessive overhang. This muffler is suitable for most mid-range displacement engines, making it a versatile option for custom projects. Installation requires careful consideration. While the muffler itself is included, mounting hardware and hangers are not. Buyers should plan to use universal exhaust clamps or fabricate custom brackets, depending on their specific vehicle's suspension geometry and desired placement. The 2.5-inch inlet means that if your existing system is a different diameter, an adapter or custom piping will be necessary. It is recommended to test-fit the muffler using clamps before welding to allow for adjustments in angle and position.
