I just got my HPD pipe, silencer, and clutch kit on and their is quite a large gain in power as well as it is LOUD. The pipe fit very nicely except I had to do some cutting and bending on the springs that hold the pipe/silencer together but it turned out well. I haven't gotten to ride it much yet but will have a better report tomm.

 

I got the MSA Spark arrestor silencer with my package, it's not annoyingly loud at all. In fact, it sounds really cool.

 

I rode it today and there is a great difference in low end. I can now pull wheelies without standing up or yanking on the bars. I bent my wheely bar this morning because I was not use to the power. I would likt to try to put a stock sport silencer on the pipe would this work??? Is their anyone who has on???

 

I used the stock silencer at first, then went to the FMF. This gave me more top end but it was louder.I ended up with the FMF and I put a three inch piece of pipe in the end of the silencer, Two inch in and one inch out,It took the popping sound out. Now it sounds good and I've got my top end too.

 

Zman, are you using the FMF Tubine Core II? Will it fit the HPD or stock Pipe? Is it LOUD?

 

Would a sport silencer fit on my trailblazer??? How did you make yours quieter???
