Tony... without doing much looking... the xyz pipe is 3"? and your TP's are not? I have been thinking about all different exhausts, but I thought about the resonated xyz and your TP's with the stock CBE until your's is complete and ready to send out... I have seen some dyno's with the stock cbe with your TP's and cheap y pipe, but nothing with the xyz... I assume it would make at least a little more power.
My other question is... why did you decide to make a 3" xyz pipe? I didn't think on NA cars there were much gains to be made with that extra 1/2"?
