I was thinking the same thing. I have worked on a number of early 1980's cars, with carburetors AND catalytic converters. Those cars also had a massive web of vacuum lines, and wires (O2 sensors that would adjust the carburetor), and most that I can think of also had air pumps to keep the Catalytic converters working properly. Once again, when you own a car you are free to do with it as you wish (even if the law says otherwise)- but is it irresponsible to be advising others that these modifications are somehow an "upgrade". --- On Sat, 2/25/12, Harold <hmcelraft@xxxxxxx> wrote: > From: Harold <hmcelraft@xxxxxxx> > Subject: [DML] Re: Advantages of Spec .01 Exhaust > To: dmcnews@xxxxxxxxxxxxxxx > Date: Saturday, February 25, 2012, 6:03 PM > "Don't let your personal biases > obscure facts." > > You're kidding around! – Right? > > 80's engines with carburetors had all sorts of timing > anomalies and usually an exhaust gas recirculation valve not > to mention a complex fuel metering system in the carbs.
