What type of Exhaust for 1980 FJ40

[MJM]

I need to know what type of exhaust system to use on my 1980 FJ40 that has full emissions with catalytic converter. Currently my exhaust tip exits the back of the truck and now that I have put on hard doors and one of Eshan's tops I can not roll up the windows with out now it is way too hot inside. I do not need the catalytic converter b/c the truck is exempt but , can I do away with it? If so will it effect the o2 sensor? Should I take this to a muffler shop and say go for it or should I go with a performance type muffler ie. flowmaster cat if yes who sells them for a good price.
I do not have headers.

Thanks

I would have sworn I replied to this this morninng, but there is no O2 sensor, its a thermal sensor. you can get rid of the cat if you want, the TS need to go someplace however, a good exhaust place can hook ya up

You can only get rid of the cat if you live in an area that does not require it.

2.5" exhaust and have it dump out behind the rear tires somewhere. But have it dump out the side.

And get a header. it helps a lot.

Flowmasters sound VERY good on a 6..

Good advice for me also as I need to get the exhaust done on the 60
Thanks guys

If some one was to cut off the thermal sensor and throw it away where could thay get a new one.

Sorry for the hijack in the previous post I would take it to a performance shop if you want to run your exhaust on the inside of the frame rail (it can get tricky getting around the gas tank in an 1980 FJ40) if you want to run it on the out side, most shops can handle it.
