Thanks Stratihey dennis,
depends on what your other mods will be. i don't think a full (engine length) unit will fit with the stock exhaust cuz that expansion bulge is pretty big.
one of the "monza" style ones like on scooby's bike will probably bolt right on. might need a _bit_ of trimming to get the front cylinder's header to clear, but that shouldn't take too much of an effort.
