I will be getting a 87 Brougham from my father soon and was wondering if the cat. converter could be removed when I go to put a new exhaust on it or will it screw up the emission equipment on the car. I want to run duals right behind the rear tires with some nice chrome tips. I am not worried about passing an emission test because I am not required to have on where I live. Also I was thinking about replacing the carb when I get the car anybody have any suggestions on what kind or should I rebuild the old Quadrajet.

Hard to beat the Quadrajet in terms of fuel economy and power. Only better would be the Edelbrock copy of the Quadrajet if you want to spend $500.

Removing the CAT will make the car a lot louder especially inside and won't hardly gain any power. If more power is what you're looking for, you're going to need a larger motor.

removing a catalytic converter is illegal and not advised! (i found that a sawzaw came in handy when i removed mine :hide: :getaway: )

^Exactly, you will fail inspection.

^Exactly, you will fail inspection.

actually, here in the land of illumina, they do not do any smog tests as of yet. besides, if they do a visual inspection, they will still see the cat. converter body: i gutted it and ran a small strait pipe from the inside.

Like I said I'm not worried about passing emissions or a visual inspection sinceI am not required either where I live. Also I have heard that after 50,000 miles the cat can be removed or replaced. I am pushing 160,000 miles now. All I want is a little more power when passing and a little more power taking off from a stop. I am not looking for a hot rod I already have one. I just want a land yatch with some power.

Heh, land yacht....I knew about the cat, and how people drill em out. Smells like poop afterwards...

I straighpiped my 85 Parisienne. Took the cat and the muffler off in one fell swoop! Oh it got louder, but I'll be damned if it actually got faster. It sounded pretty damn awesome though, once I replaced the q-jet with one of Edelbrock's Performer carbs. the 500 cfm worked great, but that was after it was no longer a computer controlled vehicle. Don't replace the stock q-jet with something else, it's computer controlled. Just my .02.

I have 94 eldo w/northstar. I live in Florida and there is no emissions here so I was thinking of removing my cat conv and running straight pipe. I will keep my orig in case I move. I wanted to know if anyone knows how the computer will respond and will the car still run smoothly. If someone knows please email me @ spdy_7@yahoo.com thanks

Well, being a '94, you have OBD1, which means no O2 sensor after the cat. You should be alright.

I fully condone catalytic converter removal! If you dont have any kindf of inspection do it! That probably had the old bead style catalyst, very restrictive despite what these enviromentalist wacko's say. you wont be dissapointed so long as you eliminate it, pipe it, and have a muffler. Go for it if you can, you won't regret it. Also to further ease your worries. "I do not represent any government or enforcement agency of air pollution" I'm not gonna tattle on you.

If you can, remove it. With 160,000 on the car, it is likely partially plugged. If this is the case, you might notice a bit more power and fuel economy, but for the most part, those 307's are pretty dead. You will get a bit more of that distinctive Oldsmobile burble, though.

I would recommend against replacing the carb with anything but what is already on there. Have the carb professionally rebuilt. Do not exchange it. These 3C carbs are pretty efficient when they are in top working order.
