Header DOUBLE WRAP?

So my titanium (the gold stuff) header wrap is looking a bit worn. Is there any drawback to just running a new layer over the old one?
Seems like it would increase the heat protection which is a plus. Can't think of a downside. Thoughts?
 
I double wrapped where the front and rear pipes meet, it saved my header from rash in an accident is about all I can say.
 
I dont wish to offend anyone here, being new and all, and im certainly not an expert on these later model Buells,, im a vintage bike guy,

But my $0.02 is pipe wraps are a bad idea, (is stupid too strong?) For some reason,, they are all the rage for motorcycles and i would have thought people would have learned by now or the word would spread,, but wraps are a very bad idea.

Now,, in a pinch or to protect another part from heat,, such as Block hugger headers running up against the starter on a Chevy muscle car, its perfectly suited to use it to shield the starter or other parts from the radiant heat.


Some years back the wraps were popular in the hot rod and muscle car circles and people found very quickly that exhausts failed very quickly, particululary in radius's because they accelerated the metal in rotting out,,it concentrated the heat even more than normal, It got so bad a number of well known magazines printed articles warning about this and a lot of the well known header and exhaust manufacturrers were very explicit about it being a bad idea, voids warrantys and just dont do it.

Bikes are not any different,, its all basic mettalurgy and physics.

If you want an excellent solution to appearance AND dramitically increasing longevity,, use a good quality ceramic coating and or heat dispersant. There are many qualified shops who can coat your pipes for reasonable prices and theres a number of colors and finishs,, IE: Satin, Gloss etc,,, I use a local shop here in Oregon,, and yes, they do handle shipping if you like, look up http://www.Finishlinecoatings.com and Russ and Lana are great people, their products are tested in landspeed record racing and customers use their stuff in all forms of racing,

AND they offer a lifetime warranty on the coatings

I coat used pipes ID & OD and on restorations of vintage bikes I often have the new chrome pipes coated on the ID as they dont blue after that,. I have had people at shows comment that my bikes are beautiful but a shame they arent ridden, BULLSHIT,, i rode it in here! (because my pipes arent blued) on a pipe coated ID and OD you wont believe how much cooler they run,, no more burnt legs or cooked parts from the radiant heat, all the heat goes out the pipes end,, not radiating.

Feel free to ignore my advice on this, im not trying to insult anyone, just my experience. Been working as a mechanic for a long time, Im also a Federally licensed Aerospace mechanic, Im certified to teach power plant theory and mechanics, and have a Mechanical Science degree. 35 years making my living as a mechanic.
 
I have always wondered about the pipes getting really hot on the inside because the wrap holds all the heat in. All of this makes sense. I think i may wrap mine anyway because they have a couple dings and dents in them, but if i get a new set, ceramic coating looks really good.

so do you use a torque wrench on oil drain plugs or not?
 
Go through the effort to remove the header, possibly snap the studs or just wrap them? Thanks ill take my chances and wrap them.
 
No offense taken annoyance. All opinions are fine.

Although your suggestion of coating is certainly valid and a great option I have to say I'm with Zeroflat on this one. For me there is just too much risk and cost involved for a full-on pipe removal and coat/dip. I can wrap my pipes myself for $50 (well ok, $50 per year if I want it to stay looking good), be done in an hour or less and my bike RARELY gets wet so the metal rotting factor should be pretty much non-existent. I live in Texas so keeping the heat off my leg when it's already 104 outside is VERY important to me. The wrap does a fairly descent job at that and I supposed a second layer will only help.

Now, if next year my pipe falls apart because I'm totally wrong on this please feel free to say "I told ya so" and then I'll have to buy a new pipe and have learned my lesson the hard way. Not the first time I've chosen that direction.

Thanks to all for the feedback.
 
Rust isn't really the problem, it's metal movement and shrinkage that causes them to crack. Getting the header wrap wet, then drying again is what does it. The tubing was bent out of it's natural shape, it's going to attempt to revert to that. Having dissimilar heat soak cycles will eventually cause them to crack and or break.

This is just one that I've repaired. I've seen several others and they've _all_ been wrapped. I personally haven't seen on cracked the same way that was _not_ wrapped. Yes, they'll break in weird places, most commonly at the O2 sensor bung from what I've seen.

Thanks! I believe I will.

I'll agree to that but I still ain't paying close to a thousand dollars to replace it after mine supposedly cracks because I wrapped it. Kudo's though, as that is a mighty crafty sales pitch.

I'm glad to see you are still on the hook. Maybe you need to get out and ride and see if you can't gain some useful knowledge instead of hanging onto others nutsacks. Are you mad because some of us have enough sense to NOT listen to your opinion? good!

"Go back to badweb?" Whats that mean? How about you keep your comments to yourself if you cant hang with the big boys?
You are so precious with your witty replies. Keep them coming.
