i appologize if this topic has been discussed already but iam unable to use the search feature for some reason.

so I had few questions:

1)who would sell them
2) best kinds
3)how much?
4)for ur dp, how many layers would u lay on it, and where else would u use it? (i drive an ix, so it comes in close to my tc)

Thanks

 

call maperformance

 

any other suggestions?
Thanks

 

I would prefer a hi-temp coating myself. The wraps are flame retardant, however if they get contaminated with engine oil you could end up with an engine bay fire. At least, equip your car with a fire extinguisher if you´re going to wrap your DP or headers.

 

where would u get the hi temp spray?

 

Why dont you try going to the auto store like, Autozone, Advance Auto, Murrays, or Orieley's. These are a few of the stores that sell them. I cant believe that you havent set foot in one, there in the exhaust isle..............wow what a topic

Try Google it really helps

 

summits got the best pricing around, i know they only really deal with domestics but heat wrap is heat wrap.
the 2" wraps the nicest with about a half and inch of overlap per wrap.

i have my dp done and the two foot section of my exhaust that passes by my rear dif.
fire extinguisher is always a good idea

 

come on man! u gotta give me more credit than that ...lol,
i did look at thier products but none of thier salesman knew what would be best to wrap our dp well to prevent tc from the generated dp heat. thus, i came to evom and thought of asking the fellow evo owners to see what they have experienced.

anyways.... i just got back from Murrays and bought the following (i will post some pics later of what i bought):

1) 2'' Conventional header wrap
2) silver insulation tape (withstands up to 1500 degrees F)
3) 3'' hose clamps

I am planning to use the convetional header wrap , then apply the adhesive silver insulation tape to prevent any possible fires (as someone suggested) then use the clamps and clamped them from both sides.

pics will be added once everything is ready to go.

Thanks for all of ur comments

 

I've had my downpipe wraped since May with no problems. I've been under the car a few times since then and it still looks good as new.

Honostly I've never heard of fire starting from header wraps. I'm not saying it cant happen but I would guess its pretty rare.

What I did hear was the metal cracking because it traps moister. But after extensive reading I found that those who had cracking problems were due to bad welds or cheap metal.

Also I'm not using any insulation tape, just a 2 inch wrap with about 1 inch overlay. It does a good job blocking heat, I never noticed any heat radiating from the downpipe.

 

- Header wrap does not ignite, so no worries there. I wouldn't bother with the 1500F silver stuff.
- A single overlapping layer is fine.
- Make sure that you wrap it as tight as possible. If its loose at all, it won't last. I used stainless steel hose clamps on both ends. 3" might be too small, but I can't remember now. Measure the diameter before going to buy the clamps.
- If you drive in winter weather, be aware that the DP usually hangs pretty low, and if you drive in deep snow, it will abrade the wrap on the bottom side of the DP.
- I used the DEI black 2" wrap from Summit Racing.

 

if you soak the wrap in water before you wrap the exhaust you will get a tighter wrap when it all dries

 

thanks guys,
ya that idea of soaking it water i think would work very well.

and with regards to the cracks, i don;t think its due to moisture since the surface would be hot enough to vaporize any moisture, however, since not all of the dp is covered with insulation (header wrap), then the dp OD surface might experience some temperature differential which would lead to surface cracks ( i think this is the cause, someone might wanna pitch in)

Thanks

 

Wrapped my downpipe 6 months ago, smells kinda funny for a few days but it goes away. It tells you in the instructions to soak it first, it makes it so much easier.

 

You have to remebe that most are made from fiber glass so if you dont want to scratch yourself and look like you have lice, make sure you wear at the least a long sleeve shirt.

I wore gloves but my sleeves were a little loose and some particles got in. Itched for a little while..

I didnt soak mine in water, but my friend held the downpipe as I wrapped it very tight. Also I didnt have any of those wrap ties, so I just used regular stianless clamps.
