Have a 'Doo or Yammy motor? Guessing it's an asphalt sled? Or run the ice?
Did lots of grass running up here.. Wouldn't having the pipes running cooler slow down the exhaust pulses, leaving you with a richer condition?

I do know that I had the pipes on my drag sled coated , they did the inside , it lowered the RPMs (2 Stroke) and I burned the motor down, because it leaned it out too much, my mistake for not checking .
I don't know if it would do so much on a V twin motor, mine was a 700 triple.

I love my Cycle Shack slip-ons and cant decided between the jackpot headers or fullsac. I'm sure its going to sound a lot better either way.
Cool stuff, thanks. I currently have my 02 sensors disconnected anyway because I'm running a PCV on a 10 Street Glide. I also run the Pro Pipe and Stage 1 air cleaner. I like the look of the Pro Pipe and all, but I still really like the sound of the Cycle Shack exhaust better than any expensive system I've ever run. I keep coming back to Cycle Shack. I asked because I'm going to have my stock 2-1 head pipe gutted, (it did do a lot to cool the engine down by changing to a catless set up), and trying a Cycle Shack Muffler on this bike as well. I have to say that by removing the stock set up and going catless, I did indeed feel as though I lost something in the low end grunt? But over all the bike seems to run smoother.

Yup, after coating my header, my muffler got a gold hot spot. If the ceramic prevents the heat from transfering through the pipe material then it must be exiting out the hole in the end of the pipe, hence higher temps in the muffler.

Same issue here. I'm thinking that the ceramic coated heat shield isn't helping either.

Yep - I (for one) agree completely with your conclusion. I bet any ceramic coated pipe with chrome on the outside was built that way because some owners prefer their pipes chromed and the manufacturer decided to offer them.
What you discovered seems to say that if you get a ceramic coated (internally) but chromed (externally) pipe, then you probably need to find the same sort of muff too.
It also shows that heat is well contained while inside a ceramic tube (whether or not that ceramic tube is on the inside or the outside of a metal tube).

Okay, so who thinks they know something about ceramic coated headers?
Both company A and company B have stepped headers. Company A puts the ceramic coating on the inside of the pipes and company B puts it on the outside of the pipes.
Is there an advantage to one way versus the other?
Is there less heat with one over the other?
How about performance wise?
Pushing the heat out the back?
Thanks for the input!

When coating both sides, we have seen well over 300 deg heat reductions directly on the headpipe near the jugs. We are confident that all of our customers will experience at least a 300 deg reduction directly on the head pipe. When testing with just the outside coating we had very poor results. I do not have exact numbers, maybe 100 deg reduction, but they were so poor if forced us to coat the inside as well.
Performance will not be affected by the ceramic coating. The only time you will see a difference in performance is on very high end racing machines where a very small gain could mean the win.
The exhaust heat will be blown out the back but it's not a big change. We have not received any negative feedback about this over the past 4 years.
Please keep in mind that coating the inside requires specialized spray guns to fully cover the pipe and doubles the cost of coating. We offer this standard on all of our true duals and full systems. The benefits of the inside/out coating were too great to not do it.

I've never seen a dyno comparison between a Rinehart system (or the Fulsac) and the (for example) Jackpot. I'd be curious to see what the difference is, if any. I do know that Jamie tested a pile of pipes before releasing his, and all his testing confirmed that a non-stepped header performed the best up to around 125 horsepower.
