When I bought the 808 it had no muffler and last year I put on a old Datsun 210 muffler I had lying around but it was not in great condition. So this year I bite the bullet and bought a brand new muffler. Nothing fancy but sounds good now. Maxim Muffler in Lethbridge did a great job on it.
Also changed the cam cover gasket as it was leaking a bit.
