Here you go, over a weekend i fitted Twin su''s and 48mm side pipe to mates minor. It had a 5.35 different but that was swapped for a 4.22 and now it's drivable since its his daily it had to be. Smithy can now pull out at roundabouts and do 60mph and keep up with traffic. You can make minors a bit more nippy.
If you pm me a email I'll send conversion photos.
