advise.....exhaust wraping
 

hello as above please, i have decided to wrap my manifold,down pipe and up pipe but need some advise.

on the maniflod (headers) should you wrap the manifold single or just double it up i.e when the manifold is bolted on underneath there is 3 bolts then from where it it mounted it then stems off in to 2 seperate pipes this is the same for both sides, hope this makes sense they are un equal if that makes any odd thanks in advance:thumb:

this has probably been asked many times sorry in advance for being thick

I`ve wrapped mine both pipes together, if i`m right in thinking this iswhat you mean, slightly different layout becasue my headers are twin scroll but you get the jist:

There is a lot of good information on the thread above.
Where possible wrap each individual runner separately for best results.
I only use DEI heat wrap having tried everything else I am aware of on the market. It is not the cheapest but for me it does the job best having taken the trouble to measure the radiated heat from headers using different wrapping material. It has another advantage in that there is stitching down each side of the 2" wide material and this stitching shows the overlap required which means it is easy to get it right and it is economical in terms of the amount of material used.

Heat wrapping is not difficult if you follow these instructions but you cannot expect to achieve a professional standard on your first heat wrap operation unless you follow these instructions exactly.
Because of the cost of heat wrap ties I only use stainless steel tie wire and generally the more ties the better the job.
To use tie wire it is best to have a set of tie wire pliers/ lock wire pliers which makes twisting the tie wire that much easier.

The DEI heat wrap has a stitching down each side to show the amount of overlap required and you should follow the overlap guide stitching where possible.
The wrap should be applied damp but not wet. You can use a house plant leaf sprayer or any other water aerosol/spray to dampen the wrap or set the tap to a very fine trickle and run the wrap through the trickle quite quickly. In a few minutes the water will have spread evenly throughout the fabric to dampen it. The wrap must not be soaking wet because the impregnated chemicals run out.
Wrap from the bottom to the top with the appropriate overlay.
Keep the wrap as tight as possible.
Remember that the wrap on the outside of a bend requires more material and therefore the corresponding inside of the bend will have big overlaps and on a tight bend this can be almost 100%.
Do not cut the wrap in to short lengths but try to apply in continuous lengths and certainly 15 feet at a time.
The rolls come in 50 foot by 2" .
A 3" open neck downpipe wll generally take three quarters of a roll of wrap done properly.
Remember. Keep it tight.
Tie at the end and then every 3 or 4 inches but on curves or corners you can increase the number of ties.
The tie must be applied while the wrap is still damp.
Cut off any strands and loose ends.
When put on the car first there will be a lot of moisture released from the wrap. Do not be alarmed.
On damp and humid days the wrap will absorb moisture so again there will be a lot of steam.
It is quite normal for the wrap to smell for three weeks after applying as it dries through thoroughly.
Happy wrapping.
If you need further assistance please do not hesitate to contact me.

Harvey Smith.
