i'm thinking about ordering a dyno max cat back for my 95 mtx i found a deal on line for 255 + s+h is this a good deal and is it worth the money My other question is i have sho shop catless y's (not happy with the amount of torque lost) I'm also ordering dyno max high flow cats but i dont know if the sho shop y pipe is 2 1/4" or 2 1/2" pipe
