Quieter? Are you talking about the pipe? Definitely not quieter, but more powerful. Tuned pipes are a must to obtain good performance out of a 2 stroke. Luckily it isn't that much louder than the stock pipe.

The new rear mount was critical in keeping the chain tension. With the stock mount it would just slide. It is solid as a rock now. No slipping and pretty easy to adjust. I put a few miles on it today and it performed nicely. I am out of gas now but plan on a long ride tomorrow.
