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

If you're looking to give your 2017-2020 Honda Civic Si Sedan a more aggressive sound and improved exhaust flow, the Skunk2 Racing MegaPower RR cat-back system is a solid choice. This system is built with decades of racing engineering in mind, aiming to maximize exhaust velocity and reduce restrictions.

The MegaPower RR features a unique Double Barrel (DB) design with parallel, dual race mufflers mounted centrally under the bumper. This setup is tuned using CNC mandrel bends and precision robotic TIG welds to produce that distinct, powerful Skunk2 exhaust note. It includes a high-flow resonator and 4-inch tips, all constructed from T-304 stainless steel for durability. While it's not a simple bolt-on system and requires basic welding and fabrication for installation, it comes with new exhaust hanger hardware designed to work with your OEM hangers for precise positioning. You'll also find new exhaust flange gaskets, bolts, and nuts included to ensure a leak-free installation.

This system is designed to be a complete cat-back solution, replacing the factory exhaust from the catalytic converter back. It's a well-built option for Civic Si owners looking for a significant upgrade in both sound and performance.
