3 Inch Mandrel Bent Exhaust...what is your recommendation , with or without Cat Conv

[hybrid]

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.

try a beudesert 2.75 inch hiflow cat save yourself a lot of grief. some not all exhibit overboost issues with the 3 inch system. and I don't know of any with the beudesert system having these issues.

What Kevin said. I have 2011 with 3" and had endless issues. Thanks to Mudski and Kevin am now sorted out after nearly 2 years of boost issues.

By the way Kev, I still owe you that KISS

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?

I have this fitted to my 2006 3.0 DI. Works a treat and is trouble free. They fitted it while I had a coffee. My nephew had one shipped to him in Newcastle, and it fitted first up.
