Which style of Trinity pipe was tested?  Old style in the mid 90's my buddy had a Trinity pipe on his LT500 that was the traditional FMF, DG, Bills style of pipe routing.  The Trinity pipe that is available today is the side pipe inframe style similar to Aaeen, Q, ect.

The Trinity pipe that was tested leaves the cylinder and angles slightly to the left and then stays on the left side of the quad.  The pipe is not as fat as the Aaen or Q pipe.  It has a two piece, two angle tail cone.  The cone next to the mid section has a much steeper angle than the cone that the stinger is attatched to.
