That does surprise me if the new cats were working as they should. Again, I know very little about 360s but with the 348 and with a much more free flow intake and exhaust setup than OEM (higher flow air filter, 200 cell cats and Tubi exhaust) I always do an ECU reset before the MOT to make sure the system is operating at optimum. Might not be something that's required with a newer car but with older ones it makes a difference.Thanks. I think my OEM cats are shot and have had some 200s fitted, but apparently they made basically no difference to the emissions over the dead OEM cats. Which I was surprised about. I suspect they weren't hot enough.
Unless the 200s are dead as well.
Each to their own, but doing that would more than likely nullify his insurance even if an accident had nothing to do with cats. It counts as an illegal modification so his insurance company wouldn’t have to pay out and he could well be charged with driving without insurance. Cat removal is checked from time to time now, police will do it on loud cars and I wouldn’t put it past an insurance company to check if it got them out of a big bill. I’m sure it makes a nice sound but possibly wouldn’t be worth it if you got caught out. High flow sports cats are arguably a smarter move.I don't know about 200 cell cats, but a mate has a 360 with a decated Capristo stage 3. He puts the cats back on to pass the MOT.
I didn't think you were technically meant to even change the catalyst on an exhaust system these days, unless the replacement part is type approved? Don't take as gospel, just based on my Googling recently given my current predicament.Each to their own, but doing that would more than likely nullify his insurance even if an accident had nothing to do with cats.

I have heard of this happening, although not yet out here in the depths of rural Lincolnshire. Just not worth the risk imo.In the past I have been pulled by plod when driving faster stuff. They do a roadside emission check as they were having a purge on cars with no cats. Last time I was in my Elise and the layby looked like a boy racers dream car park full of sports cars/hot hatches/EVO's
