exaust wrap headers

[nitrosman1]

on a monaro vxr with a full wortec system i want to reduce engine bay temps and im considering wrapping the haders and was just wondering what peoples opinions were , good or bad idea etc as iv heard this can shorten the life of an exhaust as it pushes the heat further back into the exhaust is there any compramise maybe wrapping the headers half way down

If you want to drop underhood temps drop your engine temps down to 82*C/180*F its near the optimal temp for power. Stock is near 98*C.
You can get it to 90*C by fans alone, under that a T'Stat helps

so much for stainless steel these days even when your paying that much for an exhaust i have been looking at a 160 degree stat from the states

Either way you still need to retune the fan on/off or fan % power settings a T'stat alone wont do it.

We used to wrap headers for power. Heat=energy, energy=power, ergo loose heat loose power. The problem was that the fabric wrap held moisture and that made a mess of the headers. Looks st too IMHO!

hi they look good iv got a few questions
how peter much did it cost to do both headers
how long did it take to get them done
did you have yours coated inside aswell
and did you notice any difference in exhaust note as iv heard they can make the exhaust sound quiet
thanks from ollie

hi oli
yes there dip them into a tank so it coated inside and out.

Mine came out like this they looked that good i almost didnt want to fit them lol

Not many will touch them if they`ve been on a car though.

I see that Camcoat do but don`t warrant the job.
