I have run on a straight pipe (i.e. turndown pipe only) for quite awhile. I can't really say it's worth going out and making a custom exhaust unless you can get it cheap. There is a slight reduction in turbo lag and very little power increase except at high rpms (passing on the highway at 50+) where it is there, but is not anything amazing. The real reason I like my straight pipe is the sound. NOTHING sounds (or smells) better than an unrestricted turbocharged diesel exhaust system with just a pinch of black smoke.
