I just changed the stock seat on my 2006 GT to a custom Rick Meyer one. The passenger one is great but the rider seat is better but still not right. It is narrow at the front and still slopes down towards the tank. My old K1200RS was more comfortable to ride. I added bar backs and it helped a little. Anyone else have similar problems? I also want to change the exhaust as is too quiet for me. Any thoughts on the best replacement canisters or entire exhaust systems?
