The HKS Super Turbo Twin Tail Titanium Tip Cat-Back Exhaust for the 15+ Subaru WRX & 15+ Subaru WRX STi is a high performance exhaust system for drivers seeking a system that can be driven in the street but opens up power and sound at wide-open throttle. The new Twin Tail Titanium-Tip version provides a more aggressive look and completely fills up the rear bumper!

The Super Turbo Muffler combines a low back pressure design for improved power and torque but maintains low sound levels at low RPMs for comfortable street driving. This is the perfect hybrid exhaust if you love your neighbors!

I have had the HKS Super turbo cat back fitted for a couple of months now and absolutely love it. It's marginally louder than the standard exhaust on idle. But when your foot is into it you can definitely hear it's presence. Which is perfect for daily driving responsibilities.

Why this exhaust is perfect, it does not drone. You can't hear it blocks away its tidy and looks great and a very well made product. As for fitment, it took a whole 5-10mins on a hoist. Best part no adjustments were needed. Which just shows how good the quality is.

As for Kamispeed's customer service, it was great. Whilst the part wasn't in stock it was already on order and Saku was very quick to get in touch and give me updates on what was happening.
