Built in house and calibrated with a matched ecm, average HP gain is +10% over stock, tuning is REQUIRED. 

Fits all XB models, outlet style may differ from picture. This is based on a Magnaflow 11148 muffler and has slightly better ground clearance than a stock exhaust. This example does not come with an ECM.

Everything here is hand fabricated in house, there is a short lead time of 2 to possibly 6 weeks to build as all systems are built to order.

Since you own a Buell, you know it shakes as it runs. PLEASE check the mounting hardware before/after every ride. If something is worn out, replace it. Need new clamps, ask me for some. I use Clampco clamps, they are available online at about $12 each plus shipping. Also make sure to check the front bushings at the lower front of the engine. They do wear out, replace them as required.
