MXP 2017+ Honda Civic Si Coupe Comp RS Exhaust System

With this MXP Comp RS cat-back exhaust system, you get the full cat-back assembly, including the muffler and all necessary piping to connect to your factory catalytic converter. This system is specifically made for the 2017 through 2021 Honda Civic Si Coupe models. It's designed to replace your stock exhaust from the catalytic converter back, giving your Si a more aggressive sound and improved exhaust flow.

Crafted from durable stainless steel, this exhaust is built to last and resist corrosion, even in harsh weather conditions. The Comp RS design focuses on optimizing exhaust gas flow, which can lead to a more responsive engine feel and a deeper, sportier exhaust note that's noticeable without being overwhelming. The piping is mandrel-bent to maintain consistent diameter throughout, ensuring smooth flow and preventing restrictions that can hinder performance. This attention to detail in construction means you're getting a well-built system that’s made to perform and endure.

Installing this cat-back system is a direct bolt-on affair, meaning no welding or cutting is required. It's designed to fit right onto your Civic Si Coupe's existing exhaust hangers and connect to the factory catalytic converter. While it's designed for a straightforward installation, we always recommend referring to the manufacturer's instructions for the best results. This system is a popular choice for Si owners looking to enhance their car's sound and performance.
