The Honda Civic Si has always been a fan favorite for the Thermal R&D Team. The Si is now equipped with a 1.5L turbocharged engine, making it a priority. As with all of our systems, we strive to offer the best possible combination of sound and performance. This 3” system is made of T304 Stainless Steel with a resonated mid-pipe and the signature Thermal True Helmholtz Technology. This sound control combination was engineered to achieve the desired aggressive tones during launch and acceleration, and cancel the unpleasant drone while cruising.
Because we engineer and design our products in house, we were able to offer a tip upgrade that follows the spirit of the OE design. This unique tip fills out the rear bumper while leaving no question that an upgrade has been made to the exhaust. The exhaust system comes with brush finish tubing and polished finish on the tip and muffler. Hangers mount up to the OEM brackets, allowing for an easy direct fit install. Available for both the Coupe and Sedan models.
