Yes, I did install the Shift Kit with a friend and the instructions are pretty easy to deal with. The wording is a little odd but you can figure it out. And the shift kit doesnt really chirp tires cause we dont have as much torque as the GTP'*. I have it on the highest setting now so I can shift quicker and damn does it shift. The front end of the car lurches on the 1-2 shift. But I will drop it down to the second setting for "firmer" shift so I dont break the transmission once I get the Comp Cam for our engine and Thrasher heads. That should add approx 70hp to the crank.
You really shouldnt use PVC because it might melt of something from the heat. I used aircraft aluminum from http://www.burnsstainless.com
. You could also use steel or something similar. And mine is 3" so I develop torque and velocity with the air. And I used an import foam filter because it would get all the oil on the MAF like the K&N'* tend to do over time as they keep getting cleaned and reused.
