Description
The Howe Muffler with Y-Pipe Assembly consolidates your dual exhaust merge and muffling into one compact, pre-assembled unit—eliminating the need for custom fabrication and reducing installation time. This 21-inch assembly handles dual 3-1/2 inch inlets and steps up to a 5-inch outlet, making it ideal for forced induction builds and high-flow applications where backpressure control matters. Steel construction with gray paint ensures durability in engine bay conditions while maintaining the aggressive, competition-ready aesthetic.
