About This Item

The Special 45th Anniversary Edition HKS Super Turbo Twin Tail Titanium Cat-Back Exhaust for the 15+ Subaru WRX & 15+ Subaru WRX STi is a high performance exhaust system for those with discerning taste. It uses the extremely popular Super Turbo design but is made from 100% Titanium alloy for an extremely light system.

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 titanium variant cuts the weight of the exhaust system by 50% (when compared to OEM) but still implements the dual exit quad tip design. In order to make it more exclusive, HKS is only made 45 exhaust systems world wide to celebrate their 45th Year Anniversary.

Applications:
  • Subaru WRX [VA] (2015, 2016, 2017, 2018, 2019)
  • Subaru WRX STI [VA] (2015, 2016, 2017, 2018, 2019)

HKS Super Turbo Ti Cat-Back Exhaust (Special 45th Edition)

This is the second purchase I've made with Kamispeed. This purchase along with my 1st purchase has been a painless and headache free experience. All products arrived by their estimated shipment arrival dates and undamaged. The HKS build quality is what we all expect out of HKS - second to none. Fitment. Welds. Materials. However, I discovered an issue with the connection between the mid-pipe and the downpipe when installing this exhaust. The kit calls out for the use of the spherical "ball" style gasket and the spring tensioned fasteners used with the stock exhaust between the stock downpipe assembly and stock mid-pipe. Unfortunately, I've previously changed my downpipe (which is now flat-faced) and exhaust and dumped the stock hardware. I was able to re-use the hardware from my Tomei Expreme Ti cat-back exhaust and luckily had a spare flat-faced exhaust gasket to insert between my downpipe and the HKS exhaust. This HKS exhaust kit does not come with a new replacement spherical "ball" style gasket, flat faced gasket or hardware (spring tensioned bolts, general bolts, washers and nuts). So, if your plan is to use this exhaust with the stock downpipe, keep the stock fasteners to re-use and head down to your local Subaru dealership or Subaru parts page for a new spherical "ball" style exhaust gasket. If your plan is to use this exhaust with an after-market downpipe, you will need a new flat faced exhaust gasket and either you'll need to retain your hardware and re-use them or pick up some new bolts, washers and nuts. This is why my rating for this product is 4-stars. The completeness of the kit was disappointing for an exhaust that cost this much. Performance wise? If you want an aggressive exhaust note, this exhaust is not for you.. Turbo response feels good and I'm still hitting my target boosts levels on my Cobb tune. The STi is a lot LESS angry with the HKS exhaust and tunnel blasts aren't as exciting anymore but I've been told that at some point in your life, you have to grow up. I prefer to live in denial...
