Hi all, I am looking at buying a full 3" exhaust system from a quality shop in Ipswich. Two prices have been quoted. One with a cat converter and one without. Do I have to have the converter and if not what are the good bad points of not having it,

Thanks

Daniel

Are you getting new headers with it?
Aren't the oem cats in the headers of the 08 4.8's.
Legally yes, if its high flow then it will be fine,
Your exhaust will stink without one.

Did they let you know the individual maximum fine for non emission compliance (ie removing a cat converter) is up to $15,000 when they quoted both prices?

Sounds like they are not offering quality advice thats for sure.

There is zero performance benefit or any other benefit going from a 200cel cat to no cat on a zd30.

Bloody good advice DT, I put a 200cel on mine years ago when we did the exhaust and it goes like the clappers, not worth the bloody risk not to fit a good Cat, they are giving the guy very bad advise if they are suggesting otherwise.
