Bassani's Pro Street Systems are made to produce low-end grunt. Utilizing different pipe sizes, the graduation in diameter allows this exhaust to hone in on maximum torque right where most street riders need it - "downstairs" in the rev range. 1 3/4" headpipes step up to 1 7/8" before exhaust gas finally exits through the muffler bodies to keep exhaust velocity up and move the gases out of your bike quickly.
