Supersprint used to make a back box for the 3 piece systems. We did sell and fit a few when we first started and in our opinion (and some of the current traders on here) it was the best back box ever available for these cars. The following things were noted:
- Perfect fitment to Scorpion Centre or OE Centre section
- Nice Tail Pipes which lined up properly and were straight - 90mm
- Excellent build quality with stainless steel internals and mild steel exterior
- These will outlast most stainless exhausts (ask those who have them)
- The noise is spot on!
Picture of the exhaust from Supersprint website:

In order to get Supersprint to make them we need 10 orders.
Price would be £225 per back box.
Let us know your thoughts.
Thanks
