Removing baffles on your motorcycle will not directly harm or damage the engine. However, it may result in the engine running leaner, causing a problem with its performance and complications to the emissions. Removing the baffle does not add any performance benefit or enhancements to the engine.

SoundMan. The Muffler part of the exhaust is bolted to the bike. Once you remove the bolts and the clamps they will slip off. A little effort will be needed to slide them off.

Removing the baffles will change how the engine runs. It will usually cause the engine to run leaner (less fuel), and a lean mixture burns much hotter that can cause damage. Removing the baffles will also mess up the power curve of the motor. Usually loosing power down low and gaining a slight amount up top.

Your bike will run without baffles – but if you just simply remove the baffles, without putting a good tune in your ECM to compensate, you will most likely notice a degradation in performance.

You don’t have to do any changes to motorcycle when installing a slip-on. When reducing exhaust back pressure, you should consider what it does to the air/fuel mixture. Remapping is required if you want the most performance and smoothest power delivery from your bike.

Slip-on mufflers won’t improve horsepower or performance. Slip-ons are mostly for decoration and noise enhancement. Installation on some bikes may require bodywork done by a professional at a shop.
