Should i take my CAt off?

my check engine light just came on looks like the cat is bad, i live in fla nd they dont do inspections here. whats the diff with a cat on and off. will it be louder better gas mileage

 

what makes you think it's the cat?

 

i hooked it up to the obd2 and said that it was ...

 

Ah, ok. Pulling the cat will make the downstream O2 sensor throw a fit. Might have to get a sensor simulator. URD sells them.

but it only lists installation for 05 and up and on the 4.0 only. maybe call them and see what they say.

 

NO...

 

no what???

 

honestly unless i replace the cat, im always gonna have the check engine light on, im thinkin bout knockin the guts out of the cat and if i ever move back up to PA they will see that the cat is still installed, but which way will get better gas mileage?

 

Hollowed cats sound like shit.

 

Thats why i say NO....

 

not sure where in fl you live, but i choped off the cat, and muffler.... a bit louder (ok loud enough to wake up the neighbors but i dont like them anyways) i have the 4 banger, and it sounds good. hope this helps

 

replace the cat. it's not that expenseive to do.

 

Does anybody know how long the "federally mandated emission components extended warranty" my Haynes manual talks about lasts? Would a 95 still be covered? If so maybe it can be replaced for free?

 

As for the OP fix the cat correctly, It can save you fuel and maint. issues down the road.
Find a credible shop, the can test your cat for you. I have had a couple replaced on GM vehicles, for 125.00 installed (aftermarket of cousre at a local exhaust shop.)
FYI just bc a scanner OBD2 says PO420 cat below eff, doesnt ,mean THE CAT is the problem nessecarily.

I know for GM vehicles, unless they have a warranty block (salvaged title)
or something similar, the are warrantied for 8 years, or 80k miles.

 

tru tru thanks guys... and the haynes thing and stock warranty shit is 7 years :-(
