i think i posted this b4 if i did im sorry.
ight heres the thing. my 95 gs smokes, the guy b4 me cuy the cat.converter off. therfor i have no o2 sensor.
i have another head which im ganna rebuild completly. new valves,cams, etc.
so wat i really want to no is, if i do do that with buying a complete exhaust. that should stop my smokeing correct???

 

A complete exhaust may stop the smoking...but that depends on the smoking amount and color.
If it's black, you're fine and a complete exhaust should remove a lot of that. However, if it is a constant cloud of black smoke, you have an issue with running too rich and it's only a matter of time before the new cat will clog.
One step at a time though, get the exhaust system and get back with us.

 

ok. may b a bit cause just bought tires n insurance is coming[:@]

 

i'd say get a cat-back and put a hi-flow cat on and put the O2 sensor back in.
