You probably know this but you can cut out the cat and weld in a straight pipe and the reverse the process for NCT. Sounds very not like something you'd want to do but ford2 used to swear by it and it did sound decent. He had a standard back box on his so I'd assume a good back box would be the job.

the alternative is that decat pipes can be got on ebay for as little as 30 (can't get a link as in work). They do the job I have one on mine.

For back boxes it would be e36coupe.com or gumtree.ni as they seem to be a bit thin on the ground down here. Mind you hopefully someone will pop up with one. Bluhbluh might have one.

Best of luck on the search anyway :wink:
