The term downpipe is usually referenced on turbo charger applications and is the pipe right off the turbo charger. Its also where the catalytic converter is positioned...hence the term catless downpipe.
In a ZR1 application its most commonly know as a catless x-pipe or off road pipes.
OP, get in touch with American Racing Headers they produce what your asking for and offer great fit and quality.

That's not what he's referring to. Like Poor-sha said it's the pipes with primary cats between the exhaust manifolds and the x-pipe, not the x-pipe itself.

With the stock cam the raw gas smell isn't bad. Supposedly, you can use O2 eliminators to keep the CEL from turning on (I think they're made by Big Daddy, but check with NorCal, who makes the cat delete pipes.
