Help with exhaust heat supression pls

[boatdetective]

Hey there-

So I bought a 2014 Shiver at a super price. Great engine!

As one would imagine, nothing's perfect. One of the Shiver ills is the exhaust arrangement. The cat converter is located just in front of the swing arm and funnels quite  a bit of hot air straight up to the seat and your thighs. I have a friend who makes some high end ceramic insulation and I was going to wrap the cat and pipe up to the very large exhaust can. There are sveral concerns:

-If I insulate the cat converter- will the heat only travel downstream to the exhaust can under the seat? It will be much harder to insulate the muffler.

-I can remove the cat pipe and drill out the cat. If I rip out the platinum- there will be no combustion in the tube and the heat should go down quite a bit.  Naturally- I'm not too fond of destroying any OEM equipment. I also don't know if this will mess with the sensors

-There's a mid pipe out there without the Cat in it. This may achieve the same goal- without the destruction. In this case- I'm just hoping it will fit. Once agasin- if I switch over to a non cat system- will the engine require a new map??

Thank you for the input (BTW, the members here seem way more responsive and technically adept than on the Aprilia forum- so that's why I'm reaching out to you).

Hear is my two cents worth of advice.  First I don't know what a Shiver is so this isn't specific to the bike.

If I insulate the cat converter- will the heat only travel downstream

It will definitely contain the heat and it will get hot and have to go somewhere, I wouldn't do it.

I can remove the cat pipe and drill out the cat....will mess with the sensors

I believe it will mess with the sensor.

if I switch over to a non cat system- will the engine require a new map??

It will change things and a new map may be required.
 Actually you seem to have anticipated all the problems.  Maybe it would be possible to fashion a deflector out of stainless steel that could at least deflect some of the heat while moving.  Other than that I think your best option is change out the exhaust and then re-map.  Good luck and I am sure some others with more experience with this sort of thing will chime in with some solid advice.

When I replaced the mid-pipe (Cat-Con in the Colostomy bag) for the Breva 1100 I didn't "need" a reflash for it to run well, it still ran ok.

But the exhaust got louder, and either I could now hear decel popping that was muffled before OR I picked up some decel popping that wasn't there. I think it was the former in this case.

I would suggest starting with the aftermarket mid-pipe, but be ready to possibly seek a reflash.

I'm not familiar with the exhaust or the bike, but is there a way to mate a heat shield? (like in automotive production)

Is the high heat always bothersome or only when stopped or some other once in a while condition? I ask because the minute the weather cools, all the complaints about heat seem to vanish. Maybe it is just a matter of dealing with it during the variable times when it gets a bit uncomfortable and leaving it as is?

My V65 was brutal sitting at a stop light on a 100 degree day. The rest of the time it really didn't matter much. The percentage of time sitting a light on very hot days was really small. If it is a large percentage of time, it isn't the bike.
