Does anyone out there in C4 land know of a source for a true dual exhaust system for my '91 C4 convertible?  I'm looking for a setup that will include long-tube headers, separate bullet cats, individual mufflers and all of the required tubing to go with it.  I'm building a D-1 ProCharged 383 for street use and want to have the best exhaust efficiency possible.  The intake is a TPIS Mini-Ram with reworked L98 heads and an 8.5:1 CR.  Everything else is being done to (or put in) this motor is with the blower in mind.   

Thanks for your help!

add these to what is above:








and you get this look:





TPIS long tubes, wrapped in DEI tape, and plug wires are wrapped in snapping anti-heat blankets.
And that is a 383/LT1....
