My black Supertrapp had some pretty substantial discoloration of the muffler where the collector joined, and at the aft end. The black finish began to turn a not so nice brown. Supertrapp nicely warrantied the muffler shell which I replaced after getting a good dyno tune, but a few weeks later the new one began to do the same. Turned out the "good" tune wasn't "good" enough. Still a hot running motor. Got that resolved but the discoloration was still there. To add insult to injury the collector heat shield rattled loose and slid back a couple of inches and scuffed up the finish pretty good.

So the time came to take action. Based on the recommendations of a few ppl here I picked up a rattle can of Eastwood High Temp Exhaust Coating in satin black. The can wanted a <50% humidity and 55-85 deg environment to apply, which is basically an impossibility in NY in the summer. So I managed to secure the use of a vacant office in my company's office building for two days (I know the head of the facility engineering/maintenance dept) - It was pretty cool rolling my Low Rider through the lobby in the middle of the day!

Sanded down to pretty much bare metal, acetone wipe (three actually) lots of plastic masking and painters tape. Three coats with 30 min between, then 24 hours (to the second) dry time in the nice air conditioned office.

Rolled it out at around 4pm yesterday. Eastwood wants 20 min idle to final heat cure the finish, but I wasn't thrilled at the prospect of roasting my already hot 110 motor idling, so I called their techs up. Was told that 10min, with a 10min cooldown and another 10min idle would be fine.

So I did. Came out pretty good - but only time will tell how it holds up.

Only painted the muffler itself - the heat shields are original.



The finish isn't quite as shiny as the original or the heat shields, but it's pretty damn close.

I also spoke to Supertrapp about the gap between the rear cyl heat shield and the collector shield and they are looking into getting me a replacement set. Great company to deal with.

So all in all, I can't say a damn thing about how this will look in a year, but for now, I'm happy. FWIW.

 

NICE!
Interested to know how it holds up

 

Looks good. Should be fine.

 

Nice work, Mchad! It looks great. I've painted exhausts on sport bikes and have had good results with it; until I threw them in the gravel again

Keep us posted on how it holds up; that exhaust looks right now

 

Eastwood makes and supplies some quality items. As far as the final cure, I'd just idle it around the neighborhood or town for a bit being careful not to hit a puddle of water or mud.

 

It looks good!

Cool to use an office for the project... I've always wanted to ride a motorcycle inside an office building. Many moons ago in the '80s I spent a lot of time in NYC office buildings, and I would often imagine riding the iron-head Sporty I had at the time down hallways and through rows of cubicles... It still sounds fun!

 

Nice work, i hope it holds up for you. Had you not mentioned it, per you pic i wouldnt have noticed the difference.

 

Thanks all. I'll report back in a few months to see where we are.

I wish I "rode" it. I actually pushed it along, but got similar looks as if I was blipping the throttle on the way in!

 

Nice work! It sure looks good (right now). Here's hoping it "ages" like the rest of the exhaust.

 

Looks good. If the paint doesn't hold, you may want to get the entire pipes, inside and out, ceramic coated/jet coated. I ddi this to my car headers and 6 years later they still look brand new. Very durable. Also helps cooling by pushing heat out the tail end.
