I have been following this thread for a while with lots of interest. I may still jump on the wagon and purchase a set for myself. However, I am going to go out on a limb an try something different first. I am having custom hardpipes made for my yellow MSP out of carbon fiber. The plan is to have 2" plumbing with glass smooth inside and outside finish. We played around with different colour ideas (black, yellow, weave, etc.) and we are going to try a black and yellow weave pattern. Not sure how it will turn out, but we are going to give it a shot and see what we come up with. The only unknown right now is whether the CF will be able to tolerate the temp coming out of the hot end of the turbo. We are probably also going to try a custom CF CAI as well. I'll post pics when all is said and done. Not sure what type of gains we'll get (comparable to pre-fab CAI?) but I'll try to get it on the dyno after the plumbing and my new 3" exhaust go on.
