This is an awesome system. Packaged extremely well, bolts right on. No problem with install, sounds great! Running a 152.5 main jet with airbox lid off (requires additional mods). Not sure how much power it gained over stock exhaust but it's much smoother power delivery is definitely noticable.

Perfect fit for my 94 warrior. Great quality workmanship, finish and sound.

This didn’t match with the bolt holes and it’s not angled enough to make it over the clutch pulley. Just a waste of time.
