2017-on Honda Civic Sport Hatchback (can also fit Civic Type-R, but may be loud, resonated p/n 10158603 coming for the Type R) Aggressive styling with sound to match comes with the DD-R exhaust for the Honda (FK7) Civic Sport hatchback. This high-quality race-inspired system features our unique customizable dual DD-R mufflers. The removable tips allow for different look and sound with optional tips and tip silencers. This specific DD-R enhances the flow and sound of the Sport’s L15 turbocharged engine without the need for a mid-pipe resonator. The high-quality stainless-steel construction is designed to bolt up to the factory piping and runs a 3” (76mm) piping up to the rear where it splits to dual 2.5” (63.5mm) piping via our DD-R precision Y-pipe and finally the twin signature DD-R mufflers.
