Has anyone put exhaust tape on their headers?
If I do it will it damage the cat from the increased heat?

Exhaust Header Tape
- Thread starter Doorag

Good question re the damage to the Cat....i have recently ceramic coated the headers on one of my fizzers, and the bike runs quite a bit hotter, but am guessing that the cat will cope, as the bike can run at up to 106c, and i doubt Yamaha would make a Cat that cant cope with that...so whatever the increase in running temp is with header tape, would probably do no damage...
Just taking a stab in the dark, with those comments but!

Thanks wolf. I figured that I could use the tape to cover up the really ugly looking header pipes.
I guess I can always take it off...

I wrapped my FJR header (with header specific wrap) about 3 years ago (also has a cat) to try and cut down on the heat transferred to the rider.
Helped a little bit with the heat, bike runs fine with it, no problems...

The general concencus is that the heat will slowly damage the cat. I'm talking about metal substrate cats, which I'm pretty sure the FZ uses.
There's an easy way around that, a cat-elim pipe. :rockon:
Honestly, even if it does damage the cat, it won't cause the bike any problems.
And if you're doing it to cover ugly headers, why not just clean them with a chrome polish? Super easy and they come out looking new.

what's in a cat pipe? never thought about them getting destroyed by heat.

Platinum, palladium, rhodium, cerium, iron, manganese, and nickel. All in different proportions.
As a side note: header wrap can trap moisture too, you're going to want to make sure you do a good wrap job.

I used it on the arrow mid pipe (cat pipe)

if that answer was for me, let me clarify... i wasn't asking what sort of metals... i was asking what the internals are. i assumed something inside it would fail because of the heat. i've never cut one opened and have no clue what their purpose is other than they reduce noise and help with pollution.
so is it a bunch of chambers in there or some sort of filter or both?
I was under the impression that the whole concept of a cat was to create heat in order to burn off the impurities .
As a side note my car runs with an uprated turbo running at 18psi (the header glows on full chat) my standard cat is still in perfect condition even with all the heat

kinda like a honeycomb running through the "bulge" in the pipe

Yeah, but it's not right next to your headers is it?
A catalytic converter provides an environment for a chemical reaction wherein toxic combustion by-products are converted to less-toxic substances.
This is an example of a cat. Ours is a little less dense inside, but still VERY restrictive.

It's my opinion, (NOT FACT), that a converter requires a lot of heat to function properly. Maybe I'm wrong? I think that one can run too cool to function properly but I personally don't think a little extra heat will hurt anything there, (if it doesn't cook your shock or silver heat shields).

Speaking of ceramic coating does anyone have an idea how much that costs on average in the states?
A bit off topic, but has anyone run a cat eliminator pipe but with the stock exhausts? Results?

It has always been my understanding from the sport compact Racing world that when you use header wrap the biggest problem is if it gets wet from say rain or puddles while your riding they hold water and the water combined with excessive heat can be bad for your headers. It can lead to rust or corrosion on some metals and eventually eat through the metal. They use it on drag cars because they don't ever see bad weather while hot. Your best option is to get a good set of ceramic coated headers if available.. Not sure if this applies to bikes but don't see why it wouldn't.
