Hey guys I got my new pipes last night for my 2014 250sx with a 300 kit. I got the 300xc platinum 2 pipe with a pc r304 silencer. The I got the expansion chamber on fine but the silencer is a pain and I got it mounted but I can see where the expansion chamber meets the head it's not completely flush. I read a post from somewhere that I would have to modify the silencer? Anybody got any tips for this? Photo
