R400 Duratec De Cat?

[echoone]

I have done about 10k in my 2007 R400 Duratec and it appears the cat has just gone (blocked). I believe this is the problem as the car lacks power as if blocked in the exhaust and also when I turn the engine off smoke pours of the service of the cat!!

Having just looked at the price of a replacement, I am thinking of a de cat pipe instead, mainly because I do not want to shell out on a new one if its going to block again after so low milage.

What do people think or suggest??

I think you will struggle to get through an mot without the cat. Might be worth having a closer look. I have my cat off the car and it is fairly straight throughout, I can't really see how it would get blocked.

Good luck in getting it fixed.

I built an early 2008 R400 and the cats were out of stock so I bought a by-pass pipe to get it up and running. When I was doing the post build checks, I took it to my local garage and they did MOT emissions check and it passed without the cat! Maybe it was just luck but the Duratec is quite a clean engine.

I'm based in the Midlands, is that close enough to you pat??

Redditch, Worcestershire, so fairly close depending which part of the Midlands

I'm in Wolverhampton. Let me know when you'd be in a position to help me out.

Could I ask why you run your car with a by pass pipe? Can I just replace the cat with a pipe and use the original exhaust and engine map?

Cheers
