Skunk2 MegaPower RR 17-20 Honda Civic Si Coupe Exhaust System

This Skunk2 MegaPower RR exhaust system is specifically for the 2017 through 2020 Honda Civic Si Coupe. You'll get the complete cat-back system, including dual race mufflers, a high-flow resonator, 4-inch exhaust tips, and all the necessary hardware for installation. This includes new bolt-on exhaust hanger hardware that works with your factory hangers, plus new flange gaskets, bolts, and nuts to ensure a leak-free seal. It's designed to replace your stock exhaust from the catalytic converter back, giving your Si a distinct sound and improved flow.

Skunk2 Racing has packed decades of race engineering into this Double Barrel (DB) exhaust. It's constructed from T-304 stainless steel, known for its strength and resistance to corrosion. The system uses CNC mandrel bends for smooth, consistent pipe diameters, which helps maximize exhaust velocity and reduce restrictions. Precision robotic TIG welds are used throughout for solid, reliable joints. The dual race mufflers are mounted centrally under the bumper, creating that aggressive, signature Skunk2 exhaust note that many enthusiasts look for. While it's not a simple bolt-on system and requires basic welding and fabrication for installation, the included hardware helps ensure a precise fit and proper positioning.

This system is built to enhance the performance and sound of your Civic Si Coupe. The 3-inch diameter piping and high-flow resonator work together to let your engine breathe more freely, potentially leading to improved throttle response. The dual mufflers are tuned to produce a deep, aggressive tone that stands out. If you're looking to give your Si a more visceral exhaust sound and a cleaner look with the dual tips exiting centrally, this MegaPower RR system is a well-built option.
