Would this work with OBD2 emmissions inspection, at least the electronic part of it? I assume you simply disable the Rear O2 sensor and associated CEL's. I realize in this case the phrase "off road use only" applies, but humor me.
Also, pardon my ignorance; I never had a reason to remove the cat before, but this is nominally a 25hp gain over the standard stage II kit, if I'm not mistaken. Thats a damn good reason especially when the car is driven less than 5k miles a year (which, incidentally, exempts emmissions testing in the state of PA...for now).
