Need help finding good TBI performance single exit exhaust systems

[DK5]

I'm shopping for a good system now for my '90. It has to be built to last in the winters here as I will be daily driving my K5. Anyone have some suggestions?

See mine and AJMBlazer's discussion for further information (toward the end of the thread)...

I haven't seen a lot of bolt-on performance y-pipe kits out there so I may have to go to the muffler shop

any ideas?
