how will that go with the new regs?

Probably not very well I plan to keep the cat that's on the car and swap it before any MOTs

I'm hoping if I make sure the bolts/ exhaust clamps are all super lubed up they should come off easy enough each year

Just gut the cat. Or run a dummy cat. Tiggy' is working on some ace blank ones... They have wadding so they don't sound like an empty cab

Ahh I just read about the diesel emissions test didn't realize it was just a smoke test..

So if I took the cat off and cut the top open (so it wouldn't be easy to see from under the car), gutted it, welded it back together it would still pass an MOT? Whereas an obvious de-cat would fail?

I read that, so is what I said above valid or not? As long as it doesn't look like it's been messed with its okay?

Yeah so I'll stick to my original plan of installing the DPF/ CAT before my MOT

Completely irrelevant to the 306 and other vehicles of that age. Our cars are old enough that any back-dated legislation will rarely reach us. A missing cat where one was standard has always been an MOT failure.
