    Hi,

    Are there any significant gains to be made from de-catting the 115 PD engine?

    Is it better to buy a new de-cat specific pipe or simply rake the ****e out of the current cat?

    Also, I know it can't be done in situe if you want to rake the box out rather than buy a straight pipe so could anyone direct me to the bolt sizes for the three that connect it to the zaust as I can't see these coming off without heaps of effort so will probally just grind off.


    Cheers, Sam

    I'd just gut out the stock cat.

    Its free, and also means you wont get any MOT hassle, as they've added a visual check for the presence of a cat to diesels.
