>>Thanks, Fred. I'll be ordering from them only for about half the price I have been paying at O'Reilly. Their list of what RxP does is more impressive than what I have just been saying.

>It also sounds like they're up front about their claims and point you to all the places to check them (and others) out. I'll have to try this stuff in my '73 Vette. I usually have to play the "game" of failing emissions, getting the car so de-tuned it barely runs, passing inspection, and tuning it back to usable. May not have to as the governor here in AZ has supposedly signed legislature that allows "show type" cars (non daily drivers) older than 15 years to not require emission inspections. Just waiting on the EPA to sign off on it, I hear. Anything you can do to speed that up? < bg >

Yeah, right! lol. Anyway, you are in EPA Region 9 out of San Francisco. Sounds like this exemption is part of we call a SIP (State Implementation Plan) which undergoes a fairly rigorous review by the Region's Air Programs staff.
