Total system replacement will work for 1985 through 2005 E-glides. If you´re only doing components, 1985 through about 1994 or ´94. Pipes changed from 1&3/4" to 1&7/8" I recently bought a 2004 stock system off eBay for about $175 (delivered) I´ve had several set-ups, but like the stock with straight fish-tails the best.
