You want to avoid petrol exhaust systems on a derv, as they are more restrictive. You'll want something nice and free flowing to let the exhaust gasses out as easily as possible. Also, bear in mind you only need one box in the system for it to be mot friendly. Mid box is the best one to keep, just replace the others with straight pipe. Then you'll really hear the turbo whistle!
