junkie 0 Posted September 8, 2010 If your decatting you just want a piece of pipe straight through and the lamda boss is needed so you can demoing the lambda in it's original position so your ecu can control fuel delivery. You can buy a pipe or just go to your local exhaust type place and get them to make a decat piece up. If your car is made after roughly 1991 you need the cat for mot so you could get a sports cat but then they are more expensive by alot. You could just remove all the cells to decat it and so it looks like a cat is in place but mot wise it still might not pass. Quote Share this post Link to post Share on other sites
