This topic has been brought up before but I figured some new riders might be interested... (note: I have no affiliation with any products discussed) 
Your exhaust system is a popular upgrade topic so I wanted to show some tech that I've been working with lately in case there are some that don't have any experience with ceramic coatings and their benefits...In the powersports world JetHot is the leader in ceramic coating parts to reduce heat radiation and keeps the heat in the exhaust stream which makes more power since hot exhaust moves faster than cooling exhaust...
Jethot classic 1300 series is like a shiny chrome almost, which makes it run cooler on the outside, adds performance via faster flow & keeps it looking good thru the years with a lifetime guarantee (unless overheated like on a turbo engine)...the main benefit is a reduction in radiated heat from the coated part...the same way header wrap stops heat transfer- the ceramic Jethot does the same thing without possibly compromising the metal of the header...for example- if you coat your header it reflects the heat back into the header and does not radiate heat into the surrounding parts/spaces...you can test it with a thermo gun and a coated header will only get about 300 vs bare metal 600ish + up...
here is a good KRX post...

This coating is a thin ceramic metallic composite material with ultra low emissivity and high thermal conductivity, so yes the infrared view is picking up the reduced radiation emission not exact surface temp. The total heat loss to the system is reduced via the low emissivity aided further by hot spots being reduced from the high thermal conductivity Ultra low emissivity is another way of keeping heat in without "insulating" resulting in 2 advantages: 1) faster exhaust flow and scavenging 2) reduced intake air temp (usually about 1% power per 10°F) (varies depending on engine bay and intake set up) During this particular test, the exhaust gas temp measured with thermocouples in the exhaust flow was 50 deg hotter on the coated side than the uncoated side. If you want maximum surface temp reduction we recommend our 2000 and 2500 series coating which function with more intuitive insulation (low thermal conductivity) properties and also survive higher temp applications.
I just coated a Kraftwerks KRX header at Jethot and their price includes the ceramic coating on inside & outside...without shipping- it was
$150. The combo of inside&outside adds a bit of exhaust flow performance that actually requires a jetting adjustment to account for the added flow (it's a measureable change so you know it's working) (don't worry, the KRX does this automatically via the o2 sensor...)
I'll make a separate post on the 3 most popular performance KRX exhaust systems soon with pics (stock vs Trinity Racing-Kraftwerks-& Graves full Titanium)...I have before & after pics showing the Jethot coating on the Kraftwerks header...stay tuned
