Ordered them through an exhaust shop here in HI, should be here in a couple of weeks...had to special make them from the mfr. since my car is an auto. Anyway, looking for at least 40rwhp when I install my vt stage 1 or 2's right after. (headers/cams combo). The shop has to custom extend my slp x pipe to make them work, but should be bad a__ when done.
