I am about to buy some heat wrap for my headers and I'm wondering how long of a roll should I get? Is 15ft enough? It looks like the next step up is 50ft with nothing in between. At least those are the only two sizes they have at Summit. Anyone else know a better/cheaper place to get heat wrap and how much I'll need? Thanks

 

15 ft. is cutting it pretty tight. If I were you I would get the 50 ft roll and wrap the downpipe while I was at it. I noticed a difference in the engine bay heat when I wrapped both. Also get the black color, it looks better for longer, the white/tan gets a rust look to it after time.

 

+1, just buy the longer one so that you can have enough or do your downpipe also. I double wrapped my manifold and can literally touch it when the car is running. The only thing I didn't like about wrapping is that is stinks for a while, and when it rains the wrap gets wet and steams for a while when I start my car. Other than that it does a good job of keeping things cool.

 

Cool. Thanks guys

 

You'll definitely need the 50 ft roll, it goes quick.

 

Did you get 1" or 2" wide?

 

For the header I'd get 1". It will be easier. I even used 1" on my downpipe. Don't double wrap, it isn't needed. You can touch my downpipe after running the car with no problem..Also be consistant in your overlap. You want about .125- .25" overlap

 

Just so you can see how quick it goes, this is a pic from when i wrapped my sti manifold. It took about 60-70 feet to do it. I know the sti manifold is alot bigger, but it gives u an idea

 

I used 2" w/50% overlap as recommended by the mfr on the DP and it took the whole 50' roll.

 

oh yeah, roll it on while it's wet...I got the normal white stuff and after it dried completely, painted it high temp black (1200 degF) ...it helps to keep it from unraveling and just adds another level of heat protection...

 

I recommend having your manifold Jet Hot coated. I had my downpipe coated and I can touch it bare handed after shutdown when I go to change my oil. And I'm not talking about a warm up in my garage, but about 20 miles of driving to my auto hobby shop.

 

I suggest using this on SS only if you use this on mild steel the wrappings will trap moisture and your headers will rust like mad. At least get them coated by Jet Hot or something if your using mild steel headers. Hopefully the wrappings will protect the coatings as well making sure they don't get chipped from road debris.

 

I think Jet Hot coated is the best bang for your buck...

 

I know this has been covered but I perfer HPC coating over Jet hot. May be a lil more money but the quality is there to justify it.

it will also muffle the sound slightly if you do the downpipe too. Which can be a good thing (if you want your exhaust a tad quieter...) As stated above, it sure does cool things down!
