Your computer expects the emissions hardware to be there and is tuned that way. It may run fine without it, but keep that in mind.

id do it, i removed everything as well and the only thing i noticed was more power and a better breathing/ running engine.. there is no delay whatsoever with the throttle now it revs much quicker and sounds insane compared to before plus its much easier to work on since the whole left side of the engine bay is bare.
i first snipped the belt off, removed smog pump, air conditioning/condenser all the hoses brackets and everything else it took me a little time but it was way worth it.Give a man a fish and he will be fed for a day. Teach a man to fish and he will promptly forget that he once did not know, and proceed to call anyone who asks, a n00b and flame them on the boards for being stupid.

just make sure you plug any vac lines and the smog hose. NOTE i also removed all the ac since it didnt work anyways.. so im sure i noticed it more because of that and the smog not smog alone.Last edited by cld783; 07-22-2006, 01:48 AM.Give a man a fish and he will be fed for a day.

everything can come of except for the EGR...I'd leave that on. Cats are good for emissions though...Passing the test. Fast passed with the old car wit honly EGR and cats. No smog pump or air tubes.Builder/Owner of Badass Panther Wagons

I've done away with all the emissions BS besides the cats,I'm keeping those because I don't want my exhaust to be that loud.Engine stills runs the same as before only with a slightly better throttle responce.If you decide to disconnect the egr system,leave the egr sensor still connected with the chrome metal rod in the sensor fully extended out,this will make the ecm believe the egr is still there(only allways closed),and that way it won't start acting up.

Leave the cats and EGR, dump the smog pump and air pipes. Leave the control solenoids for the diverter valve and cap the lines off. Should cause you no issues. My car passes NJ state dyno test emissions with no trouble with this setup.86 Lincoln Town Car (Galactica).

Does the exhaust smell bad without the cats? I know that clogged or poisoned cats can smell like rotten eggs, so will it smell like that without them at all? And what does it mean when the cats are "poisoned"?88 Town Car (wrecked, for sale)

Dyno numbers to prove this?i removed everything as well and the only thing i noticed was more power and a better breathing/ running engine
As for the smell without cats, you will have more unburnt fuel exiting the tailpipes, so it will smell a bit more.
