Pro Circuit 296 clearance

[TEEEE]

Help! I'm installing a PC Platinum 2 pipe and a PC 296 SA on my 2002 KDX 200. The pipe matches up fine but the spark arrestor is crazy long and hits the rear fender (stock) so badly that it won't bolt up. I've heard of others using spacers for clearance, but then it will ride well outside the fender. Have any others had this problem? Should I just shave out the rear fender?

Thanks,
