Has anyone replaced the standard exhaust system with a decat system?

Looking to do this on mine to free up even more horses and MPG

Cheers Clogz :)

I was going to get a full system from the cat to the backboxes done. A nice turboback, decat, straight through has been my favourite on cars in the past :)

I have been thinking about doing the same to my 1.9 but wasnt sure if it would throw up any faults with the lambda sensor being after the cat..?

I did this to my 1.9 jtd 156 as it didnt have a sensor in the cat and it made a big difference though I didnt use a special decat pipe, I just bought a second hand cat for about £25 and took the middle out.

I'm not sure about the 2.4 but the 1.9 uses the same cat as a vauxhall vectra and there is plenty on ebay for about £45 so I might try it, I think the 8 valve vauxhall uses the cat with the sensor after the cat.
