Any thoughts on the performance of these?

You can get LT's for around the same price. Shorty's might help a little, but the numbers won't be close to what you'll gain with LT's. For the price tag on them, I'd leave the stock manifolds.

After pulling the stock minifolds off the 02 LS1, I've always thought of the stock manifolds as the next closests thing to shortie headers. I can't see where shorties on an LSX motor would benefit.

Skip it for the Longtubes. The flow on the stock LS3 manifolds are pretty good I don't imagine picking up much more with those especially with the prices.

Long tubes are legal. Get them with a catted x-pipe and tune it.

Most modern headers will come with O2 sensor fittings and sometimes require O2 sensor extender wires.
