Topic: exhaust tape

[nmmone]

were did the whole exhaust tape thing come from?

[bucky katt]

we talking about the asbestos cloth wrap to insulate or the kind of tape that gets sticky when you wrap it around a hot pipe, used to patch small holes?

[tramp]

the exhaust tape is supposed to keep the heat in the exhaust pipes
so the outside of the pipe is cooler

[rustrocket92]

I thought it was to keep the inside of pipe warmer to help exhaust gas flow faster.  
 
I got this from the manufacturer :

Exhaust Insulating Wrap (Graphite Black)


The original Exhaust Insulating Wrap was developed over 12 years ago by Thermo-Tec. Exhaust Insulating Wrap is an innovative way to create more horsepower and reduce under-hood temperatures.

Wrapping headers maintains hotter exhaust gases that exit the system faster through decreased density. Increased exhaust scavenging is produced, along with lower intake temperatures. Exhaust Insulating Wrap withstands continuous heat up to 2000°F, and contains no asbestos.

Thermo-Tec exhaust wrap will not over-insulate a system when properly installed due to a proprietary coating developed by Thermo-Tec - Thermal Conduction Technology (TCT) - that conducts heat across the wrap's surface. This coating controls heat build-up and dissipation.

you also have to worry about the tape getting wet
it holds moisture and can rust your exhaust pipes out
it does void any warrenty your headders had

The alternative to tape is to have your pipes coated with a ceramic thermal coat, no worry with rusting.

nmmone were you asking what it is for or where did originate ?

[nmmone]

well i always seen it on rat bikes or old street bikes. I was curios to know if its was for anything or do people just put on for looks

[Sam Green Racing]

On anything other than a race motor, it's probably for looks.

Head off to your friendly A/C engine overhaul Shop and get them to metalize your pipes as an experiment to see if they can expand their market in services, aluminum spray is cool.
