On the standard Ludix Blaster exhaust there is a part of the exhaust fitted to the down pipe that allows exhaust gases to escape and for the effectivness of the exhausts expansion chamber to be limited.
The exhaust is derestricted by chopping this pipe very short and then crimping it together and welding the seam. This makes the exhausts expansion chamber to perform as designed and helps the engine to produce more power.
As you can see from the picture this one was chopped and welded but not as close as I would have liked.
I decided to replace the exhaust with a Leo Vince Handmade TT. This exhaust also comes in restricted form, but it is restricted in a different manner.
