Part 1 of 2 videos showing how I modified the standard silencer on my Triumph Street Triple RS 765.

In this part I show how I cut the silencer open and remove the cat and outlet pipe, weld in a larger diameter pipe and fit the heat shield.

In part 2. Welding in the perforated tube, packing the silencer with wadding and final welding, painting and fitting to the bike.

And of course, First start!
