The 9th Generation Si exhaust is the first Honda system that introduced our True Helmholtz Technology, offering a top of the line sound in this catback exhaust system. The 2.5” system is made of T304 Stainless Steel with a resonated midpipe and Thermal's signature Helmholtz chamber. This sound control combination was engineered to achieve the desired tone at launch and acceleration, while cancelling the dreaded drone during cruising.    

The 4.5” angle cut tip completes the Thermal’s variation on the 9th Gen exhaust. Available in both 4 door and coupe, the system’s tubing is brush finished while mufflers and tip are polished. Hangers mount up to the OEM allowing for and easy direct fit install.

Thermal R&D Exhaust systems are designed with quality of sound and manufacturing as our number one goal. Built from T304 Stainless Steel, the fit and finish of our products are designed for performance on both the street and the track. Understanding that the exhaust is the starting point for many builds, our high-performance exhaust will allow additional modifications to perform at their peak. We engineer our products with the goal of achieving the best all-around product for a given application.
