Hey Guys I was just curious as to whether many people have de-catted thier tdi's, i have heard of it being done and am quite tempted to give it a go, see what difference it makes, What are your oppionions? My plan is to find a scrap 1.9tdi and take the cat with all hosing etc on it and then remove the cat, weld in a bit of pipe so that it has the requite flanges etc and then directly replace my cat with the new de-cat, is that how other people have done it or are there actual kits you can buy? Also, i have heard from a few people that diesel's don't legaly require a catalytic converter, has anyone else heard this? Thanks Adam PS: Should have the initial mods to the car sorted soon, 18inch RS4's are being collected on saturday, tuning box should be here this week, 40mm lower (i think i will be going with the Venom kit.) suspension should be ordered next week, then the black projector lights will be ordered once i have been paid next week, i can't wait!
