You are correct, I had the Sikky kit but that shouldnt matter that much. Even if his engine is a bit lower or slighty back more (though mine is as tight as it gets IMO) the routing for the piping will be pretty much the same.
If I recall correctly I used 2.25-inch piping to the first cat since that's the diameter it is then I went to 2.5-inch after the second cat.
