the Prodrive cats will pass an MOT but they can be hard work to sort..........

Great, I,m going to try it, will keep my original cat just in case.

Once you've replaced the cat and the whole system has just a single Prodrive cat you'll instantly notice just how much quicker the turbo spools up and you should feel a little extra boost as well. Keep an eye on the rev counter and you should feel/notice the turbo spooling up maybe 100 or 200rpm sooner. It really will make that much difference now that your engine can breathe properly. Enjoy

Just had a look underneath my car and the pipe connected to my backbox looks like it,s a straight through pipe so won,t need to change that either.
