Exhaust grumble?

[vk]

I had a milltek cat-back exhaust on old Fabia VRS PD130 which was tuned - it didn't have a down-pipe suprisingly but EGR delete, custom code tune with a Forge FMIC and LWFW + everything else - it drove really well. Anyways - that had a really nice exhaust tone to it, which you could hear over the engine. I've got some old videos floating around on an old hard drive - I can try and find them to put them up if you want. I had a SEAT Leon FR with the CR 125kw Diesel engine - that sounded pretty nice too and that was stock.

Are these DPF cars though?

Nah the Fabia wasn't but the FR was - maybe SEAT did something different with their exhaust system to VW - they do have a habit of taking VW's and making them a lot better to drive.

I don't know Australian road rules too well, but it isn't illegal to have no DPF in the UK, just a CAT.

Hmm, Im quite new to this, does the downpipe bypass the dpf and then connect to the cat, or does it completely remove both?

Either way, from all the reading I have done, removing the DPF seems to be illegal in aus

Yeah it's a toughy, I was pretty nervous doing an emissions test after having the EGR removed on the VRS - but it passed as if it had just come out of the factory. I bet DPF's don't make much difference to emissions anyways, but I wouldn't want to risk it or pay for it to be done. Just leave it as it is

How much did it cost to do an emissions test?

Guys bottom line is changing ANY part of the emission system is illegal in Australia, and whilst DPF's are new amd not widely known about, the fines for doing so are flipping huge. I will NOT be running a DPF delete, despite the fact I have the delete pipe downstairs and a Viezu tuning deal as well now. It's FAR too obvious and the car will blow a lot of ugly black soot, and that's no longer cool these days, I hate following soot belching diesels, plus there's no need for that in modern cars. At an emission test with no load, you probably get away with it, but in the real world, you'll get dobbed in, and the only option is to wait for better technology in DPF's and prey my experiemnt works if ever I can actually get a core out of the manufacturer. Even that will be borderline legal at best.

The DPF is part of the exhaust pipe, a dump "delete" pipe replaces the front half and the DPF, and there is no way to bypass it, that was my initial idea, but it's not possible with the sensors used in the system, will throw errors and eventually put the car into limp mode.

For now you're stuck with it mate!
