Product Description
The Supreme SP cat-back exhaust, for the turbocharged 10th generation 2017+ Honda Civic Sport hatchback, improves the performance, sound quality and styling. The system incorporates large 76mm (3 inch) piping designed to be as straight and smooth as possible. At the end the catback uses a single muffler with dual exits as opposed to the heavy factory dual muffler design. This allows the turbocharged L15 engine to be more efficient for added performance, without having drone or being loud.

The Supreme SP sound level was carefully tuned not to require any additional resonators; reducing weight and cost. The polished stainless-steel center-exit exhaust is finished off with iconic dual, double-wall, slant cut GReddy tips. Like all GReddy Supreme SP systems, the fully hand-welded 304 Stainless-Steel exhausts carry a Limited Lifetime Warranty
