749er, you could.......
Buy new Termi assymetric can, carbon cover, link pipe, filters + ancillaries (no ecu) = approx £550
Buy a PCIII for a 748 off fleaBay (same but cheaper) = approx £150
Have it all setup on dyno (IMHO, better than 1 size fits all DP ecu) = approx £100
Enjoy spending the change (from not buying the ecu) on some bling (if that's your bag) or a couple of trackdays.
