Here is the dyno graph
http://www.geocities.com/breaux124/dyno.html

Warpspeed is in red and cattman is in blue.
It's kind of hard to follow because both torque and horsepower are on the graph.

To help: The power graph starts at the bottom and after the graphs cross it's on the top


Here is my original review of the two Y-pipes:

Good work! Looks like WSP has more power down low, and Cattman more up high. Did you guys just bolt up and run between each pipe?

I had two runs with the Warpspeed Y-pipe.
There was a delay, then we installed the Cattman Y-pipe and did two more dyno runs. They were about 5hours apart.

Basically the Y-pipes perform the same.
