u will make more power with a 3 into 1 collector exhaust. drag pipes/straight pipes only make HP ina very narrow rpm range, org designed for HD circle track racing.
search David Vizard exhaust for some great info esp about the best 6 cyl exhaust to make. A lot of crossover headers.

Thanks CA, I only went because my mobile dyno man is 5' tall and was worried about getting squashed by the Valk in his van  
I wanted a before/after comparison for the winter's mods, not gonna get serious about it, but it was great fun.

I'm an old fashioned sort of guy anyway, I like one carb and one exhaust per cylinder, just seems right.

My quarter mile time is sprinting, not drag racing, and will be faster because the clock only starts when I decide to break the beam with my front wheel, not how quickly I react to the must go green of drag racing. Worth upto 0.2 of a second apparently, but doesn't affect the terminal speed.

11.4 sec 118mph in 4th gear. we will get much faster as soon as we figure out how to keep the tire from breaking loose when  shifting into second.

1. recruited an outstanding Valkyrie Rider
2. Car tire on the back
3. Blower with a single carb on top of the motor.

OK Mike, you're on. I'll even spot you a couple feet, just name the time and place. heh heh
