downpipes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hi guys,
I thought I'd try to start a discussion about downpipes.
Assuming--
(1) we want sbc's with straight rams horns and have lowered our trucks 5-6"
Routed over trans crossmember and through trailing arm crossmember.
Out the back.
This has got to be a very common design - right?
So- who knows where to buy a bolt on system.
I have not been able to find downpipes that are correct, although the Corvette size ones will fit (using Corvette 2 1/2" straight rams horns).
We ought to be able to convince someone to make these.
I asked Flowmaster , but they moved their r&d to Idaho.
Who else can we get to make this system?
Thanks for any info or leads.
