Sorry if this is beat. I've been away from the forums for some time, and the search feature is disabled (?).

What was the final word on the performance difference between the two pipes?

I have a "test monkey" build of the WSP pipe in my garage that I removed after early testing showed a HP loss. Has anything changed? If there's actually a performance difference, can anyone explain where that may come from?

 

some people have complained about the WSP pipe quality. I have the cattman y, and the fit and finish was perfect. I had no install problems...Also, the cattman is S/S..

 

What about performance? Both units look identical from a design standpoint.

 

from what i've heard if you have 00-01 and live in a warmer climate(no snow) then get the warpseed. If you have a 02-03 get the cattman because the warpseed fittment is off.
