Post by: Budgie on December 07, 2007, 22:32:06: Matt, the CAT is on the downpipe, it's that box just behind the flexy. :wink:

You can use an early 95 downpipe that just has the flexy in it, or 300TDi Defender downpipe that is just the pipe (no flexy).
The Defender one is LR Part No: ESR2297
The non-cat Disco one is LR Part No: ESR2740

Mine's pre-cat anyway AFAIK - hence my not knowing where it was!

I think they were standard fitment from 95/96 on, although I've been wrong plenty of times before. :wink:
