This tip is used when you don't have to run a muffler. It induces a VACUMN effect on the engine thus making more power and especially throttle response.. When ordered with a pipe we will tac weld it onto the pipe per your request via email..
This tip is not to be used with our Solution Series Flathead Pipes. We have other pipes with this tip installed that will do a better job.. This tip helps ALL engines..
This tip will fit any pipe that a RLV BL91 Muffler fits (1 5/16ths id )
The Booster Tip is uncoated with no protection from rust etc,
