Anyone know what the surface temp of the stock muffler is? I was wondering if it's below 980F, thereby allowing me to use the G2 High Temp Engine Paint System to get a nice gloss finish... they have so many cool colors available, all in durable gloss that looks awesome. http://g2usa.com/ | ||

Early in 08, if my memory serves me correct, Blake posted something in the mid 500'F range for the Buell muffs. We argued a lot about throwing fuel upon it!  Good times in learning, I guess...and NO, I don't mean to rattle BLAKE's chain. Its in archives, somewhere... You should be good to go as I cannot see the muff being 1000'F unless your near meltdown. Who's got their point and shoot temp gun handy? | ||

I think the temp is around 800 at idle on the exhaust right next to the engine. And it climbs drastically after you twist the throttle. As for the using engine paint on the muffler I wouldn't. It will eventually bake off. You need a paint that will stand up to 1200 degrees | ||

Misterrich, 1200 degrees is @ thin wall steel's critical point? The primaries are s/s, good for higher temp but the muff is of steel? Surely you did not measure half of this temp @ the muffler? | ||
| Misterrich |
Im not saying the temps reach 1200 degrees but the paint you need should be rated up to that so it wont bake off over time. | ||

Gloss black powder coat or ceramic coating. More durable. That's what I'd like to do to mine this winter. | ||

I've already gone thru a big can of 1800 degree BarB-Q paint. Started #2 a month ago... Z | ||

I have a muffler out being ceramic coated now. I'll post pictures as soon as I get it back. | ||

almost all the paint on my muffler has completely baked off, painted it 3 times now. Trackday alone took care of most of it. If you look at where the headers meet the muff you will see what i mean. Nick  and that was just 2 sessions into a 2 day... yeah, shes a nice pewter gray now. | ||

Loretta does not run lean, if anything, she's been rich. Even so, when I let her idle much longer than the time it takes to get to temp, the head-pipes start to glow. I've seen it a couple of times, once it was quite bright orange. Of course the muffler doesn't get that hot, but... Z | ||

Friday when I get to work I will shoot mine with a IR gun to get a proper temp at the pipes and connection to muffler and bach near the exhaust and give all of us some real data. In the next several weeks I'll pull the headers off and ceramic coat them and post the after affects again. While I got it off I'm gona ceramic the muffler also. All in Black Thoughts? Les | ||

I plan on painting mine with Por15 when the time comes: http://www.por15.com/prodinfo.asp?grp=BV&dept=8 I have used a lot of Por15 products, they aren't cheap but well worth the money,have some of this left over from painting the mufflers and stacks on tractors. This stuff is tough, if anyone uses it, don't get it on you, wear gloves or you will have to wear it off. | ||

I saw a dyno run of a bike and where the header pipes go into the muffler down about 8 inches on the muffler it was glowing red! I guess I don't ride mine hard enough because my paint is still on it. | ||

My dealer powder coated mine under warranty.  | ||

POR15 is not intended for exhausts, it will not hold up...Ceramic coating is the only permanent solution...I have it on the header and turbo housings on a dragbike...the exhaust runs white hot in the traps...no failures on the coating. | ||

I used high temp silicone black header paint rated at 1500 degrees. Hold up well but requires several bake cycles to cure. | ||
| Cscutt |
Fast1075, your right, standard POR15 is not intended for exhaust, that is why you want POR15 black velvet, it is intended for exhaust. I have several exhaust system on large turbo diesels painted with this, it holds up great even with 1325 EGT. I would agree that ceramic coating would be more permanent, POR15 requires a reapplication about every 3yrs from my experience. I have never had anything ceramic coated, how expensive is it? | ||

$150 max + shipping. look at the ceramic coating thread Les |
