HKS Super Turbo Dual Stainless Steel Tip Catback Exhaust 2015-2021 STI
The HKS Exhaust System for the 2015+ STI is designed for enthusiasts who want a perfect balance of performance and refinement. Delivering strong power and an aggressive exhaust note at wide-open throttle, it remains quiet and unobtrusive at low RPMs during street driving, thanks to its low back-pressure design—your neighbors will appreciate it.
Constructed entirely from durable SUS304 stainless steel, the system features 75mm piping transitioning to dual 60mm and finishing with a quad 54mm exit, providing both optimal flow and a visually striking appearance. The exhaust comes complete with all necessary gaskets and hardware for a straightforward installation.

Note: A OEM Downpipe to 3in Cat Back Adapter may be necessary if the diameter of the new cat-back exhaust systems piping is different from the stock system, or if there are compatibility issues between the new components and the existing downpipe.
