I am still looking at the Scrambler 1200 XC and test rode it again, but even on a short ride the heat from the exhaust was very noticeable to uncomfortable even with jeans.

I wonder if anyone has modified their exhaust heatshields (de-catting is not an option here, sadly.. or maybe not sadly, I am usually in favour of not removing 'green' features when not necessary)...

Anyway, would it be possible to
a) remove the heatshield and add some aerogel insulation on the inside?
There are apparently aerogels that are both gluable and water/weatherproof?
b) do the same but without glue (wedge aerogels between the exhaust and another layer or metal

c) add an extra heatshield at the points where the rider's and piliion's legs would be (again with aerogel or such)
to clamp onto the existing heatshield from the outside?


What would any drawbacks of this be (other than looks)?

I've organised for Meerkat Mufflers to do a de-cat. I care for the environment as much as anyone, but I know how much less heat my Thruxton generates after a de-cat. I guess my perspective is different living in wide open spaces with absolutely zero air quality issues.

The Scrambler will be an issue with any sort of extra insulation - as Peter said to me, the catalytic converter has to glow red hot to do its job, and that heat source right beside the rider's knee is always going to be a problem...
Just think about how much less fuel you'll use without that incredible restriction ;>)

Just to be clear, the particulates that aren’t being captured by a cat (because it was removed) are still going into the air. And air is really a global quality. What goes into the air in LA... eventually makes its way to the Midwest (and beyond). So making sure all exhausts are as clean as can be helps everyone, regardless of where you live.

A great example of this is on the documentary One Strange Rock. It shows how the windstorms in the Sahara Desert make their way all the way to the Amazon rainforests and are much of the rain forests fertilizer!

The Earth and its connectedness is amassing and beautiful!

I remember seeing a youtube video of someone putting just basic heat reflective shielding on the inside of the heat shield. This would A) reflect heat back to the cat and thus make it more efficient in doing its job (I didn't know they need to be red hot) and B) diffuse more heat through the back of the heat shield. The downside here is that you're reflecting heat back at your motor... so I'm unsure what that would do to it. Maybe others can chime in?

I was thinking about this the other day. It actually doesn't bother me a ton, unless I'm kinda waddling the bike backward into/out of a parking spot, as I usually leave my right foot on the peg. Only time it really gets me is having my right leg down on a hot day and not wearing overpants.

I think the best bet would be to add an additional thin layer of insulation and heat shielding on the inside of the factory heat shields. Probably a ceramic header coating could work too I think, to keep some more heat in the pipes. I am not sure how many other solutions there are. Obvious one being to move your leg, but I know different peoples' legs are near different parts of the exhaust. I am not sure if you could get aerogel in a piece to conform to the exhaust. From what I've seen, they seem to be little brittle rectangular pieces right?

I didn’t realize they came in rolls like that. Maybe that would work. I think something like a turbo blanket for the exhaust could work too, but that’s basically header wrap and we run into the warranty voiding issue again

Agree with you mate, i'm also not one for de-catting the pipes. I'm taking delivery of my 1200 XC on the 28th of this month. Admittedly, there's a R-E-A-L issue with heat from the pipes, especially where I live now...in Bangalore, India. Took it for a test-spin and came back with the inside of my right-leg nearly COOKED!! Runs SUPER-hot with the Cat. Was ALMOST a deal-breaker for me. So I was thinking of wrapping the pipes with a Heat wrap from JUST after the Cat, under the heat-shields . Any thoughts?

I was thinking of trying something like this:

Just not sure about glue and whether tbe heat might destroy the aerogel's water phobic properties. The product description said 3 it loses that at 350degC

Hi ,
I believe that soon Euro-6 and BS-6 fuel for petrol will role out where sulphur content is reduced and use this will be win win for both Euro-4,BS-4 and older engines. Hence I feel if you De-Cat your bike it is fine ... the problem is in the fuel if you understand what I mean, cheers guys I own a scrambler 900cc.
