Fitting the Scorpion decat pipe should be quite a simple mod. It wasn't for me, but I think it was worth it! The bike runs and sounds much better now. I do however, think it's over-priced for a piece of bent pipe with a nut welded onto it! It's also called sometimes called a mid pipe or Catalytic Converter replacement pipe.
I needed some Holts firegum (liquid gasket as the pipes didn't fit properly when I installed my cans before) and a mini blowtorch thing. I'll explain how I used them later:-
This is the original decat pipe I was sent next to the stock decat pipe:-
This is the replacement pipe. I was sent the 2004-2006 pipe instead of the 2007-2009 pipe which was an inch too short:-
I realised when taking off my cans that the Y pipe had a smaller exit to the can on the left side of the bike than the right to make the flow equal:-
And another view of it:-
I had to take the seat, side pods, tail unit, current exhaust cans and stock decat pipe. The instructions with the cans and decat pipe are absolutely useless, you need a Haynes manual to do this or have done it several times like I have!
One of the first annoyances (apart from being sent the wrong pipe in the first time) was that the Scorpion cat replacement pipe did not fit onto the Y pipe going to my Scorpion exhaust cans. They were basically exactly the same size. I tried squashing and expanding the Scorpion Y pipe, but it wouldn't go inside or outside of the decat pipe. In the end, I had to get my angle grinder and cut 4 slits into end of the decat pipe that fits to the Y pipe. Then I was able to squash it down using hose clamps so that it fitteed into the end of the Y pipe.
I used lots of Holts Firegum inside and around all of the joints. This is how it looks like when it is wet:-
I followed instructions on the Internet and used the blowtorch to heat up the firegum all over to dry it out before running the bike. It's really cool stuff. When it gets hot it bubbles, expands to fill gaps and dries hard:-
Here you can see the cool new decat pipe from the rear:-
