i have a 03 yz 450 and was wondering if i bought just the silencer-a pro circuit ti-4- if it would fit on to my stock head pipe. is any one running this set up or know if it will work/fit? i know they sell just the silencer so i would assume it will work but not sure. thanks

I have the t-4 silencer and it fit no problem.

Here's a pic back in '03 when I first put it on. http://i19.photobuck...o/Moto/PC_3.jpg

I have the GP system, but the silencer will work with the stock header. Make sure you get the right year model.

GP stands for "Grand Prix". It's a grand-prix motocross designed pipe. You won't have to rejet unless your jetting is already way off, however to get the most out of the pipe you will have to adjust your fuel screw, most likely. You have to replace the mid-pipe as well.
