We put a muffler for a 9170 case on our ST325. Made a world of difference compared to the straight pipe. Upgraded since, but wished we had done it years ago. Bolts on the fender where the stack is now, just drill new holes, and little pipe modification needed if I remember right. Then you just need to get the A/C to blow cold :)
