TR6 Hi Perf Exhaust

["Jeff S. Hapke" <hapkejs@cig.mot.com>]

Hello
        I've been looking for a real Hi Perf system for the six. (The system I
have now is killing me slowly from CO leaks)
I have read that a 6-3-1 header is the way to go, but I have not been able to
locate this in any catalog.
Does anyone have a source for the 6-3-1 header?
What about the rest of the system?
The 2 pipe system should flow better that a single 2.5" pipe....any
suggestions?
TIA
