Message	:that even @ 2.5" we effectivally have a 5" exhaust. How many Supra's etc have that? :The symetric nature of our exhaust and engine layout really doesn't require a dual 3" pipe. Not to be a smart ass, but actually its like having a ~3.5 inch pipe (surface ara of 2 2.5 inch pipes is about 39.25 sqin and the surface area of a 5 inch pipe is 78.5 sqin - twice as much flow) (((2.5^2)x3.14)*2/3.14)^(1/2) = 3.5355 FWIW -L.K.
