Hi Mikey, you could send a pm to renault4mad, he runs a Renault workshop down here in Cornwall, he's a good chap, and he could give you the part numbers of the bits you need, well atleast the muffler, so you can try your local factors. If nobody else on the forum can help, you could go to Melun Retro Passion a French firm or Der Franzose from Germany, both have websites, they are sure to have the muffler you require, and in both cases you can download their parts lists. Of course there is always eBay. The manifold shouldnt be a problem, somebody here should have one. Good luck, regards Brian.
