You can be fined to up to $20 000.

Dont be cheap.. buy a good cat... there really not that expensive.

Even simpler, if you can't afford a cat how were you planning on tuning it? Install a carby.

Depends where you live as to odds of being caught and how you drive day to day, if you drive like a moron you will be more likely to get detailed scutiny by any authorities you annoy.

What you save by not buying the cat covers the fee for your tune!

Smart ass questions gets smart ass answers...

Why pay $500 for something when something that costs $100 will do the same job?

Cause its legal?? Ever sped, done skids, smoked dope etc

Ever not been a tight ass?

You spend 20-25k on a nice car then do backyard mods to it like a commodore...

yeah.. well done.

I cant belive with all the Experts on here no one has mentioned OVERBOOST,

oftern when people cut out the cat they then need to do the wastegate/flapper mod to regain proper control of boost.

a bit off topic...when I first started my job in parts it was with a Expensive Daewoo dealer. I use to order off GMH and sell these bolt in pipes that use to replace the cat convertor in VL Commodores. These pipes were for New Zealand spec VL`s that dont have cat convertors. After a couple of dozen of these pipes sold GM wised up to what I was doing and removed the pipe from the master parts file disabling it to be ordered anymore.

ROFL,,,good one mate, I would've done the same....

Hmmmm, speaking of tight ass, look at your mods? cat back only! what about the extra $500 for a dump pipe!

Who's the tight ass now...
