how much wrap needed for a downpipe?
I'm about to put on an HKS downpipe in a few days and I am going to wrap it. Can anybody who has done this recommend a width and length of roll to purchase? I've seen 1" and 2" widths and a bunch of different lengths.
Thanks

it's to keep temperatures within the engine compartment down.
It should be noted that if your manifold/dp is coated in a heat treatment then wrapping is reported to be detrimental to the coating.

yes.
either get the heat coating or the wrap, never both.
a good thing to do is BEFORE starting to wrap, make sure the DP is clean as a whistle.... then spray this sealant that you spray over the wrap to seal it and prevent any moisture from collecting. the name of it escapes me atm.
this will reduce the risk of rust, and will help the wrap do its job.
also soak the wrap in water for a good while, this will make it very easy to work with and you wont get the itchiness that you would if it was dry.
THEN after wrapping the DP and using the straps so the wrap doesnt fray over time, spray the same sealing spray over the wrap and this will ensure that little or no risk of the DP developing rust.
this is how i did the RE-A DP on my dads FD and it works well. 2 year later it still hasn't frayed and the bay temps have dropped considerably.

Or do the job right and get your downpipe ceramic coated. It's only about $100 or so for the coating, and good ceramic coating is damn near bulletproof. I took a wire wheel on a bench grinder to the Jet-Hot 2000 coating on my downpipe, didn't even touch it.
Not to mention every time you do something with the downpipe you get itchy fiberglass junk all over you.
