Good spot Jasp - you are a keen lad
I doubt his 8 bhp increase claim though as it uses the narrow connecting tubes (the same as on my SS from the same supplier).
Also, it looks like a 2 into 1 as I cant see the 2nd outlet or am I missing something?
If you spot any 41mm FCR's for peanuts - shout me will ya
