   whats best exhuast set up for a vtr turbo.
   would it be down pipe back with a nice large bore and then a free flowing back box ie a jap can.
   
   or would it still be a supersprint, magnex ect ect

   I will be going for 3 inch straight through with a nice large box. I will be fitting flanges to enable me to bolt on a standard cat for the MOT. I would say the more free flowing the exhaust is, the better, so not sure supersprint / pugsport etc would be suitable really. Would be interested to see what other people have used on their turbo's.

   the above is the best idea.
   
   Most people run 2.5 inch pipework, only time i have seen 3 inch used is when running more than 350 bhp, there is a 106 running 340 bhp at the fly and he is using 2.5 inch without any restrictions
