Push your Honda Civic Si to stand out in power and sound with a new aftermarket exhaust system from CARiD. CARiD sells a wide variety of Honda Civic Si custom exhaust systems for all 1983 - 2013 Civic Si models. Each Honda Civic Si custom system is built to increase exhaust flow to the maximum for optimal performance. When spent gases have all been sucked into the exhaust system and are not clogging it, the engine effectively takes in clean air and fuel which it requires for power generation. Because their pipes are wider in diameter than those of the stock exhaust, custom exhaust systems reduce backpressure and subsequently increase horsepower. The stock exhaust system, being smaller, causes a rise in backpressure level which results in loss of horsepower. Borla, Flowmaster, MagnaFlow and Injen all have custom built exhausts for each Honda Civic Si model. Replace your stock exhaust system with any of these complete exhaust systems for 10% extra power and torque.

Using a performance header, muffler or catalytic converter alongside the custom exhaust system will give you between 10hp and 20hp more. All the brands mentioned above and others like RBP and Onki have a range of exhaust components that you can use alongside your exhaust system for additional boosts in performance. When buying both the complete exhaust system and individual exhaust components, it is important to choose the product that is designed for your year, model and trim in order to get maximum increase in horsepower, torque and efficiency. One other thing you’ll be grateful to the custom exhaust system for is better sound. All our Honda Civic Si exhaust systems have a roaring exhaust tone which becomes more aggressive with speed increases, but never gets out of control.
