From a basic back to back of the two, the Race will give more BHP and rev higher, the overall tourqe of the engine will be down and itll pick up from around 6K, the Supertourer will give less peak BHP but come on pipe earlier, around the 5200-5500 mark, the engine tourqe will be greater with a flatter power curve, that will both have more BHP as it comes on in the rev range and hang on to the BHP longer when the Race will drop off quickly, The race is great if your sprinting or blasting about on a short ride, the Supertourer is is what it says, the much better choice for touring rallies and extended days riding
That was what I thought when choosing the pipe to go with my GT186 kit, but I had a conversation with Richard Taylor who told me that he has a Supertourer and was disappointed with it and that the Race was an all round better pipe, so I went for that and haven't been disappointed.
