There is a 4th reason to do exhaust wraps - thermal control. I have an air cooled dirt bike where the header pipe is very close to the cylinder body and the carb bowl. Instead of making heat shields, a good wrap helped cut down the radiant heat soaking the bowl - and maybe helped keep a little heat out of the cylinder itself. It also helps with keeping my right leg from roasting, so bonus!

Very good point. On one of my Harleys the exhaust is right near the oil tank. And it burns the shit out of my pants. But the main reason I want to wrap it is to keep more heat off of the other shit. For example the oil tank.

This is what i was wondering about as well. Let's say you have an air/oil cooled bandit with the headers straight in front of the block, would an exhaust wrap help cooling the block, since the moving air wouldn't be heated as much by the headers before hitting the cooling fans of the block?

I prefer the look and reduction of labor when I don't have to fool around with the shields. To those that worry about corrosion just don't let the wrap stay wet on the pipes any longer than needed. They dry out quickly with minimal steam production once the engine is running. Been running wrap for years now. Glad to hear that it helped performance a small bit. Thanks for the clear explanation.

Excellent description...could you continue the explanation about speed of the sound wave/efficiency of scavenging, with respect to other aspects of the exhaust...mainly the impact on scavenging of removing or downsizing the cat, and the impact of pipe diameter? That’s the age old problem many people try to solve to increase power (along with tuning the length of the exhaust). As it’s possible to buy E marked cats that are much smaller than OEM, and which fit inside the diameter of the header pipe, it’d be interesting to know the impact of removal or downsizing on scavenging : )

The main practical reason to use exhaust wrap is to mitigate heat soak. In cars, wrapped headers will reduce underhood temps, which can then result in more power by allowing you to advance timing without incurring detonation. In turbo cars, cooler temps can allow you to reliably run higher boost. On motorcycles, the exhaust pipes often run by the oil pan, your legs, and other things that work better when not cooking. If your bike is air-cooled, keeping hot exhaust gases away can open up similar tuning opportunities as with cars.
@davem5333
5 жыл бұрын
A wrapped exhaust system may have more back pressure due to the fact that the exhaust gases remain hot longer. As the gases cool, the exhaust gas contracts, flowing more freely out the pipe. Exhaust pipes on turbo systems are rarely wrapped because it causes too much heat to be retained in the exhaust system, causing the turbocharger center section bearing to fail or the oil to coke up.

The truth is it's most often done on street bikes to cover old corroded pipes. Before wrapping became fashionable the usual, and effective way to cover up old shit was barbeque black flat black paint. My reaction to fashionable mods supposedly done for performance is "dyno slips before and after or fuck off". You can measure everything an engine does. Wrap is quick and cheap. Having old pipes blasted then ceramic coated or spray metallized is not cheap for most owners. I've peeled enough of it off customer bikes to have no fondness for it, but if you are selling a motorcycle it can tidy things up.

i mean suprisingly many people think a turbo spinns by flow, and never even imagine its a waste heat energy recovery device. what hurts is they are nowdays mostly utilised for no more than stuffing more air into engines. terribly wrong. sure if you want power and fuel economy is not in your interest it is a hefty idea, however.. there is a limit what you can achieve. and a lot of heat energy is still there, you could do turbo-compunds.. nowdays you could absolutely get an electric generator powered with a turbine and use that to power an electric motor. turbo compounding has been done in the past but pure mechanical solutions simply made it have a narrow range of being usefull.. however we can play with coupling by dc-dc converters, and variable gemoetry turbines. (actualy it allready patented so good luck seeing this emerge anytime soon) . hydraulic coupling was given a go but it was clumsy and not efficient enough. actually i don't really know any kind of internal combustion engine that would not enefit to some extent from a turbo.. even if it does no more than reduce the "pressure loss" of the intake system. in fact many tractor engies get to have a turbo for nothing more than that, "boost" pressures in the range of 0.1-0.2 BAR or so... since they don't swap pistons out and not modify the fuel system to account for any extra pressure. what they get is better fuel economy. and when you burn like 50-100 liter of fuel a day, even 1% is a lot. ust-kamenogorsk.all.biz/en/turbocompressor-of-tkp-6-tt01-mtz-g1670520#.WT3HK7-1H3g these run for a funny 250 euro -ish. sure 61mm is not a really lot but it gets the job done.
