[NSRCA-discussion] Pipe Length for 18.1

Interesting comments will have to give on of these a try. I like to have 
more speed available so the  18.1 X 10.1  sounds more appropriate than the 
W. Am I correct on this?
Does anyone have a pipe length glow plug to baffle since I cut my headers? 
Inches, MM, cubits, etc.
