De-catting the 2.5 TDI...
I'm interested in de-catting the car, and I think I'm having a bit of a hard time understanding just how many of them there are? :S
I've read about a pre-cat, a cat and a DPF; I didn't think diesels had cats as they would clog too easily?
Either case, I need to know which section of pipe needs replacing in order to eliminate all of the crap. I aim to keep the middle and back sections standard just in case I fancied replacing them at a later date.
Hope that all made sense! Any info would be greatly appreciated :)
