Well my brother who lives about 300yds away finally uncorked the yfz. That thing is crazy now, it pulls even harder than it did in stock form which is hard to believe. We put the pipe on last night and got to try it out today. We also put a 165 main jet with the needle on the 4th clip, and a k&n filter with the adapter. The pipe seems to make power great on the bottom but seems to really excell in the midrange, we didnot try to get a top speed evaluation may do it later. It is not as loud as I thought it would be either. I guess we can relly tell something about it when we go to the track Wednesday for practice. For the price of the kit I would recommend it to anyone it is a really great deal.

 

tryintoohard,
see if you can get hooked up with someone that has a db meter. I'm curious about the sound output, cuase that is a good package that they have. Otherwise you can get one at radio shack also for a resonable price.
