Im thinking about making a custion undertail exhaust for my F3 by running it out where the brake light goes. There is a shop that can bend tubing and weld in place and Im thinking about having them do that and then adding a slip on yosh. Any ideas or thoughts on this? how about ideas for a brake light if I romved the stock one.

You could always get one of those strips that have like 20 leds real close together.

Do you have enough room to route the pipe past the swingarm, shock and linkage?
