Bugster,
I am not a gold fan, but if you like it, cool.
I would go with the 5 spoke. Those are pretty darn sweet!
Now, as far as the pipe goes.
The Sumo is THE best performing pipe for a big motor, and UNREAL craftmanship! Hands down the best pipe out.
3 overbore, CnC or Spaz ported head, and Megacyclye .385 cams, and you're looking at a 240-250hp 1441cc KILLER!
Combined with the weight you will loose with the header and carbon wheels and LOOK OUT!
Let the fun begin!
What color are you getting, BTW?
