I bought this kit from True Blue for my 2015 ST. I had my local dealer install it to keep the warranty. What a difference. The little car is much more responsive and more fun to drive than when stock. After this I decided to put the exhaust kit, part number M-5200-FST on and with both on I look forward to taking the car out at every opportunity. The crazy thing is that now when driving normally (hard to do) the car gets significantly better mileage and pulls really hard from idle all the way to redline. I don't do this too often but it is a real rush when I do. This was money well spent.
