It's illegal and an immediate MOT fail if you're in the UK.
Why would you want to?
Whether it was your question or not you shouldn't do it due to the legalities.Yes I am aware of the legal & MOT position but this was not my question. I had a regen issue with a 2Ltr BMW diesel & knocked out the CAT leaving the empty box. The car now ticks over better has more power and better fuel consumption and has no MOT issues.

Rather than bodge something to get around an issue fix it properly as designed, especially where emissions are concerned.
If you don't have MOT issues that says more about your tester than your vehicle. Try going to a tester that does the test properly and see how you get on....
OP still hasn’t bitten though.
Why do people buy the lowest powered variant of a car with real performance promise, then suggest doing things like this to it..?
Leave things as they are regarding exhaust just a stage one remap will give you better performance and won’t make any difference to the emissions, removing the cats on the diesel does little for the exhaust flow unless your looking at stage 2/3 tuning, a simple stage one will take you to around 280bhp and 600+ tourques
Sure. But don’t expect not to be given opinion either. What you’ve proposed is illegal. So, therefore, don’t do it.I only joined this forum yesterday in the hope of sharing knowledge with like minded car enthusiasts not to be lectured to! A little knowledge can be a dangerous thing!!!
Then that speaks poorly towards your morals and ethics. I’m alright Jack, but screw the rest of you!I am old school, I want to produce power by burning fuel and have no interest in hybrid or electric. I don’t have the funds to have a choice in what model which chosen power so my first Merc just needed to be a diesel and then I can work on it to resolve its faults like leaking oil cooler and coolant issues. I want my engine to be able to breath in and out freely and what ever power that produces is fine by me.
Indeed it can.I only joined this forum yesterday in the hope of sharing knowledge with like minded car enthusiasts not to be lectured to! A little knowledge can be a dangerous thing!!!
