Invidia 12-13 Honda Civic Si K24 Coupe Q300 Rolled Stainless Steel Tip Cat-back Exhaust

The Invidia Q300 cat-back exhaust system is built with 2.5-inch diameter piping, a key measurement that balances exhaust flow with maintaining good low-end torque for your 2012-2015 Honda Civic Si Coupe. This system is designed to replace the factory exhaust from the catalytic converter back, offering a more refined and sporty sound profile without being overly aggressive. The Q300 mufflers are specifically tuned to reduce drone at cruising speeds, making it a comfortable choice for daily driving or longer trips.

Constructed from well-built stainless steel, this cat-back exhaust is made to resist corrosion and withstand the rigors of road use. The piping diameter of 2.5 inches is optimized for the K24 engine found in the Si models, helping to improve exhaust gas scavenging for a slight increase in throttle response. The system culminates in attractive rolled stainless steel tips, adding a clean, performance-oriented look to the rear of your Civic. Installation is designed to be a direct bolt-on replacement for the stock exhaust, simplifying the process.

This Invidia cat-back exhaust system is a solid option for Civic Si owners looking for an improved exhaust note and a touch of style. It's a well-known system that balances performance enhancements with everyday drivability, avoiding excessive noise that can become tiresome. You'll find that the sound is deeper and more resonant than stock, especially when you get on the throttle, but it settles down nicely when you're just cruising.
