When it came time to replace the exhaust system, I got lucky. I wanted a canister-style muffler, and quickly found a new FMF dirt bike can on eBay for a measly $100. The hanger bracket that now comes off the rear shock's top mount came from Vance & Hines; at $50 it was pricey, but necessary. The head pipe is stock, but covered in header wrap for an old-school look. Once I had the muffler and header installed, I brought the bike to a local custom tube bender who charged only $45 for a beautiful, stainless steel midpipe, complete with spring hook tabs welded on, sportbike-style. Very clean!
