I would prefer ceramic coating them versus wrapping the pipe. One thing I'm concerned with on the wrap method is the guage of the pipe the exhaust is made from. I'm worried the extra heat held in the pipe would be detremental to the metal in the pipe itself causing premature erosion and fatigue. I have no basis for saying this other than on a SCCA sports racer I used to run had a custom header/exhaust on a stock block. We were always concerned with heat managment because we'd tweak the AFRs so lean that the engine was always on the edge of disaster. Problem was the pipe was made from such a thin gauge in order to hold down weight (and cost too I'm sure) that if we wrapped it it would need replacing at least once during a season. Just looking at the Harley's exhaust it doesn't seem any thicker than the car's. Once it was available and we ceramic coated the header and exhaust we had no more issues and temps were down approx 12-15% as measured by the IR gun.

 

I had my 09 Ultra pipes wrapped from the headers back to the V&H slip ons when new. Just removed the pipes at 35K to install a D&D Fatcat. My experience is that the wrap does reduce the heat off the pipes, but does nothing for the heat off the heads, which is the big heat problem on the Ultra. My wrap was hard to see behind the shields. Yet, I had pretty bad heat issues at altitude in Colorado in August last summer. I'm looking to the Fatcat plus a good dyno tune to help out with the heat issue this summer.

 

If the bike is sitting outside in a rainstorm, but once you start it up it will burn all moisture out. The wrap will not trap moisture in. If you have ever installed it, you will know that its best to soak the wrap in water when you install it.

 

I agree. But ya know, there was a guy on here awhile back and I guess he was from Rainy Seattle or something cause he had pictures of his pipes after he removed the wrap and the pipes were totally rusted through and ruined.

Something like that...I forget.

Yes, I've installed and know you have to get it wet - not trying to turn this into a wrap battle - but until you start the engine and burn it off, it still holds moisture - even if the bike is sitting, the wrap will hold moisture on humid days until it is started again.

 

I have read that installing the Xied's helps reduce the temps, which is probably my first move. After that, I like the Klockworks true dual setup. Im hoping that between the two, I oughta be able to at least make some sort of heat improvement for the passenger and myself in traffic. I certainly would hate to wrap those $500 klockworks pipes just to ruin them. I might look into the ceramic coating option, depending on $

 

I put wrap on my heads and I think, they are just as hot as before. My boot has melting to it a couple time and I would not dare touch it after riding!

 

I wrapped mine over a year ago,painted it with high heat resistance paint,put the heat shields back on,and went on a 3,100mi tour over 14 days. My wife said she could definately tell a big difference. Now that I have the full stage pne on my bike,I still have the wrap on (Too lazy to remove it and it is still on tight) and it made an even bigger difference.

 

And to think a simple cam change would have eliminated the problem at the source...

 

I have a set of Xied's that I bought for $40 from someone on here. I don't need them anymone since I did the PCIII,let me know if your interested in them. I take $35 plus shipping.
