Pro-Circuit T4 exhaust system??????

Has anyone tried the Pro-Circuit T4 exhaust

system yet???????

If so, what do ya think??? Fit? Finish?

Power????? I see they say its tuneable

with the endcap?? Anyone try different

end caps????

I wanted to get either a T4 or a new R-Series last week from White Bros but neither of them are in yet.
