http://www.hpcoatings.com - get it done right, have these guys coat it. It will look better than the wrap, work better, and won't hold water that can lead to corrosion and promote cracking.
but if you MUST wrap it, http://www.buschurracing.com sells it and they're in Ohio, so freight should be pretty cheap to NY.

cityhugo: you don't need to thermal wrap the entire exhaust. really, you only need to wrap the header and thats it. the goal is to keep the heat in the headers so that you have high temps and pressures going into the turbine of the turbo. wrapping the downpipe will only keep some of the heat out of the engine compartment, but serves no other purpose. wrapping from the downpipe back would be worthless.
dustin03: yes you should heat wrap AND/or thermal coat the after market header. in fact, i think it would be silly to buy one and not do it. keeping the heat in is the goal and both methods help.
i should have made a writeup on how to heat wrap headers when we did our race car. it's not that difficult, but the key to making it look nice is to soak the wrap in water and get it moist, then start wrapping. use a piece of safety wire to hold one end in place, and then start wrapping down. soaking it will let it stretch while you apply it so that when it drys, it pulls tight to the header giving a much nicer clean look.

wrapping the down pipe would be benificial if you have a high flow cat. the heat would raise the catalise in the tube and in return have the unburned gas burn up. just my two cents
