Looking to possibly trade exhaust systems for my 01 YZ426. I currently have the FMF Titanium 4 system with a spark arrestor end cap. Not sure if this is a full system or just a new mid pipe and silencer (bought bike used). Looking for possibly full stock system with FMF Q series muffler or equivelent sounding exhaust to lower DB to reasonable level (must have spark arrestor). Bike is probably borderline right now on sound level with current setup and I tried the quiet insert but it kills all bottom end power. I ride mostly forest trails and such and want to do my part to keep the trails open . USA inquiries only please, International shipping is to expensive.
