Hey guys i just ordered berks header and since it doesnt allow to reinstall the heatshield im going to wrap up with some header/thermo wrap whatever its called, i know jet hot is much easier but i love how wrapped headers look. Are there any brands that are well known for producing quality wrap, im mainly doing it for the looks but i also want one that wont melt or crack the header.

And also how hard is it to do this? Should i find an exhaust shop to do this? Or find someone thats done it before, i heard it can crack if you tighten it too much or it wont cool as effecient if its not evenly layered.

 

The main point in this is to not only keep some heat away from the other engine bay components, but also to keep the heat inside the header for increased flow which results in more power. Hot gases flow better then cold. So it serves two purposes. Ive never wrapped one before but have seen a few and doesn't look very complicated. I would go for it myself, but thats just me. Every one I have seen has pretty even spacing between the wrap, about half covered as you make your next revolution, just keep working your way down. I have never heard about problems with too tight or two loose being an issue, but i'm not the header wrap guru either. I would say it needs to be tight enough to stay secure and in place, no more, no less. Hope that helps some.

 

good stuff

 

so do I start from the top or the bottom? and I have to cut it different times to wrap each 'tube' or just go back down the header when I reach the top and kind of do an up and down motion? or cut different strips and only do 1 layer for each tube. hope I'm making sense lol

 

I heard header wrap makes it more prone to crack

 

Why? Because the header walls are thin and can over heat? I don't know... but would be nice to, this is the only reason as to why I would think this would happen. Some more people with header wrap will continue to chime in and state their experiences. Id consider doing it with the stock header for some added performance. Anyone do this?

 

As far as I can see the only way really is to cut each one individual, starting at the top and working your way down to the collector. What I don't know is how do you secure the beginning and end points and with what? I can't tell what those are in the pick, Zip tie's would melt you would think, so some kind of steel version? Or butterfly clip like used for a bandage or what?

 

so then the end of the header will have more layers than each individual tube? Where can i get some of this stuff anyways? My local auto store doesnt have any.

 

Possibly, but you may not have to run all primaries to the full length over the collector, just run a few down to the base of the primary before wrapping the collector so the collector isn't thick with all four layers, maybe just one or two. Seems reasonable and possible to me. Maybe where people have had cracking issues is from to many layers. Hopefully someone else chimes in here with some good info.

I know that B&B auto parts has carried this, however I don't know if they are nation wide or not. You may not have one.

 

This is a stock header with all brackets ground off....havent had any problems yet and it looks a ton better then before. I dont see how this would cause cracking but who knows...
