2nd tank in TD90

I'm converting my ex TD 200tdi 90 to run on veg oil using heat exchanger kit and two tanks. Got a nice ally tank from a mate who had it made for a Disco. It fits nicely between the chassis rails at the back but the TD exhaust is in the way. Question: can I reroute the exhaust to run through the top of the nearside wheel arch, is there a simple fix like using the back end of a TD5 exhaust, or any ideas?

Thanks, Jim.

you hit the nail on the head with your question and then your answer - thats what I'm doing with my twin tanked TD 90 - only I'm using a td5 tank.
