TIFORCE FULL TITANIUM EXHAUST SYSTEMS have tapered headpipes, 4:2:1 design, and titanium oval mufflers-all for the cost of competitors' stainless steel systems. Manufactured in Suzuka, Japan and imported exclusively by Orient Express, these systems really deliver! Oval canisters have a straight-through baffle core and some of the most awesome sounds this side of a MotoGP bike deep- mellow rumble to sweet high-pitched scream-a maximum 98 decibels.
I didn't see where it said 4:2:1:2 exhaust system. I can only find High or Std Mount.
