how we fix cats up here are we take them off our cars and use a long rod and ram them down the cat untill you have the cat gutted(works on real cats too ha ha) put it back on your car and drive it. I would never purposely put one ona car unless I HAD to pass emisions.

 

Please no, you don't need them, they weren't supposed to be on the classics, and like previously stated, why choke your engine with them. Just forget the idea all together.

 

I had the unfortunate experience of living in the bowels of Idaho for a few years. East indeed.

 

i think your nuts i doubt your engine would get them hot enough to work. and if you place them in the wrong spot to close to the engine or to far back its just like not having one.every car and truck i have owned i took all the smog crap off cats egr pcv valve. i do run a valve cover breather works fine. the way i look at if your mustang needed cats they would been on there when it was made. unless your gonna use a efi 302 out of a fox body your just gonna kill power and get worse gas milage.

 

Take the money for the cats...and...

Run out and buy yourself some carbon credits!
Sleep guilt free!

Why dont you have a pcv valve? it actually increases gas mileage?

PCV valve hurts my engine...been there, done that. Depends on what you're runnin' as to what works...but cats will not work on a carb'd car without a bunch of add-ons...including a lot of insulation to prevent cabin fires. The biggest thing is that a carb'd engine can't run lean enough to heat up the cats so they can do their job as well. They do make better cats that take less heat, but a carb'd engine will still have problems.

BTW...the air pumps that push air into the cats were a coverup...injecting air into the stream to get the averages where the EPA wanted them...

 

pcv dumps in the carb/intake a breather it dumps in the air i dont know if it helps mpg i do it since it looks better and no oily gas pumping in my intake.

 

wow, great reply.
