well, here is the reason why i would want one.
1) most exhaust comes with 60mm piping, which is 2.25". for most NA tune setup, it's best to run with 2" piping... because u'll get to keep the low end torque part too. especially on a SOHC engine... 2.25" is too much thus hurts the performance on the low end.
2) by using this... i can adjust the passage of exhaust flow from my greddy evo exhaust and thus would help me out a bit on the low end part.
3) this kinda of part is mainly used on turbo setup, in which i'll be running later this year when edelbrock releases their D16 turbo kit.
yeah i too have seen it in super street... but i can't find it no more... damn!
