Alright guys, I'm guessing this might be a problem for a few of us since the changes to the MOT guidelines, so I thought I'd start a thread.
So I, like many of you, have decatted my HDi. Unfortunately, unlike most, I didn't just butcher the cat, as I already had a stainless cat back, so I got a stainless decat front pipe.
Now, the new mot regs require a visual check for a cat, which obviously I will fail, so what's the best way of dealing with this? Shall i:
1. Make a dummy cat, with a pipe straight through the middle, and weld in place of a bit which i cut out of mine.
2. Attach a dummy cat to the outside of my exhaust, by cutting it down the middle, and then welding it shut on the outside of the pipe where the cat used to be.
3. Build some sort of front pipe I can take in and out for the MOT, by modifying my current system so it has a flange.
4. Get a full, standard system on the cheap (or borrow one?) and swap it at Mot time.
5. Other
How are you guys planning on dealing with it? Pain in the arse, but somehow it's got to be done.
Cheers fellas.
