These pipes have a great deep, throaty tone that are much louder than the stock exhaust. As far as volume goes, we rate them a 6-7 on a 1-10 scale. These pipes are as awesome looking as they are sounding, always generating compliments! At approximately 20" long these pipes are just a bit shorter than the factory exhaust. TAB Performance pipes are designed to be easily installed by yourself and can put on and ready to go in about 15 minutes - including taking off your factory pipes using only a few simple tools. TAB pipes require no additional hardware or drilling for installation and your factory pipe clamps and mounting points are all used. TAB pipes are mounted the same way as your factory pipes.
As with any exhaust changes that you make to your bike there will be a difference in back pressure which requires an air/fuel mixture correction to ensure the peak performance of your engine and prevent possible damage. TAB Performance offers a plug-and-play Auto Tuner system to correct this issue. TAB Performance is not responsible nor held liable for any damage caused to the motorcycle due to not making proper fuel system changes.
