it makes a noticeable difference in terms of lower underhood temps.
theoretically, the scavenging effect will increase hp, but i would not expect a dramatic or noticeable increase in engines producing less than 300hp. it's hard to say without dyno data.
the reason i did it was because i had the headers out of the car and was sanding off existing rust and recoating with hi-temp paint anyway. it was relatively easy to wrap it at the same time.
i have not heard anything about them, but a quick search on ebay says they are ~$175. They look pretty much exactly the same as my Hotshot headers...which i believe i paid ~$300 for.
i assumed you know that it deletes the 3-way cat. so you will no longer be emissions legal.
underhood temps. will increase without all that heavy thick iron and heat shield to dissipate it (your plastic hood rod retainer could become brittle and break)
not sure if they are coated or stainless, but they could rust after a few years.
it sounds nice with a stock exhaust but may be too loud with an aftermarket.
it may be tricky to line up the gaskets on either end of the B-pipe so you don't have an exhaust leak. you may have to loosen the bolts and reposition the O-seals a few times to get it right.
if you don't, it will not sound right and may feel boggy.
lifting the original manifold out is easier with 2 ppl or a crane....it is HEAVY.
does the heat wrap actually make a noticeable difference?
i heard if you use titanium heat wrap it can actually make a difference of up to 85%, idk if that's true or not

alright, thanks...
oh, and have you heard anything about obx? i heard that their headers are really good for being headers off ebay...and idea?

some things to consider:
they are way lighter than the stock manifold.
underhood temps. will increase without all that heavy thick iron and heat shield to dissipate it (your plastic hood rod retainer could become brittle and break)
not sure if they are coated or stainless, but they could rust after a few years.
it sounds nice with a stock exhaust but may be too loud with an aftermarket.
you will most likely feel some high end gains.
