I dont know whats up with my tibby, but I get inspected in PA, which has pretty close if not the same emissions as Cali, anyway...I got a 4-2-1 header with a 2.5" test pipe with a 30" glasspack ...no cats at all...still no CEL (but I use 93 octane)...anyone know why this is because I shouldn't be able to pass but I do with flying colors?? so in my opinion I say go without the cats

 

Ehhh they were probably lazy and didn't bother to check it right. Cali they will get under your car and if they don't see two cats they will fail you. Most states are starting to do visual tests like that as well as sniffing the exhaust (did they do that with yours?).

 

On KRD Tib 1997 in stock there is only one cat converter and 1 O2 sensor.

I asked shop to make a glass pack from my cat converter. So if you look under my car you'll see a cat converter, but it's empty inside with holed tube and fiberglass around that pipe.

Ukrainian emissions test is puting probe in tail pipe and reading CO and CH on a gauge. Emisions are not so strick as in US.

I'm gonna test how much CO and CH I have in eshaust. And we'll see.

 

Yes the did the sniffer test and a visual inspection...i have a fake cat....looks normal but just a pipe goin through...

 

i must agree with ultra use a glasspack, use a 18" u will have a low grow to you ride and not sound like a tree cutter, laugh.gif

 

Yes it will. One fuel-injected car without a cat produces as much pollution as ten fuel injected cars with a cat on average. Add to that the fact that you won't see any significant increase in performance over a high flow cat, but you will now sound like every riced out Civic, and there's no reason not to use a cat.

Get a Carsound or Catco cat.

 

trust us.. car makers do not put parts on cars that do not have to be there. A cat is an EXPENSIVE item to put on a car if it does not have to be there. Maybe someday cars will not have to have them, they will be that efficent and clean, but in the meantime we would all like to wake up in the morning and take a deep breath of semi-clean air.

And when I say expensive, you have to realise that car makers can make tons of money by simply using less washers on a car. We are talking pennies in savings a car, but it all adds up over a couple of hundred thousand cars.

 

I definately will go with high-flow CAT in future although it's expensive here.
But not now, cause I need to do some mods and repairs.
