3 Inch Mandrel Bent Exhaust...what is your recommendation , with or without Cat Conv
Hi Guy's,
I have a GU 2010 and i am about to put on a 3 Inch Exhaust to help keep her cool. There seem's to be so many options out there, i am just wondering is there some better than others? should i buy one with a catalytic converter or without.
Any suggestions would be greatly appreciated.
Thanks
Renee

legally you should keep a cat on it as there are big fines if you are caught without it, having said that I’ve never known anyone that has been caught or even tested.

I was pulled over a while back in a roadside rta block and they crawled under my car. While they didn't say anything I assumed they were looking for a cat. So there's always a chance.

I have a 2011 and a 3" Taipan exhaust with cat and resonator and have never had an issue, apart from breaking a mounting lug due to not being aligned correctly. Never had boost issues.
Is not as loud as other 3" exhaust IMO.

So are you saying that a 3 inch exhaust system causes the turbo spikes? and that's why you need the dawes valve?
