Any recomendations for High performance Exhaust systems. No cat required.

Try a custom stainless job. http://burnsstainless.com Much cheaper than a $600 B&B Triflow that will crack over time and boom your eardrums into pulp. Loud does not equal power. See a custom E30 M3 job at http://www.e30m3performance.com/installs/installs-2/exhaust/exh1.htm

I am going to try this with a catalyst, because I have strict state and emissions standards in VA. The stock E28 M5 exhaust is a frickin pig. You can get better acceleration just from the weight reduction!! If you go to a single pipe, you would need at least a 2.75" diameter. The stock system is twin 50mm ID (1.97") pipes. A 3" pipe would be easier to source, bend (more exhaust shops would have a 3" mandrel), and find proper 3" mufflers, resonators, and catalytic converters.
