Remus CB Exhaust

[Sippy]

Whats going on with Remus? I just got a call from Sporttour, saying that they can't get the Remus CB exhaust for my '06 (this is after they told me originally it was going to be a 2 week wait). They couldn't be more specific if Remus discontinued that product or what the issue was, only that they wouldn't be getting one from Remus.

Got a reply back from Remus:

"... The carbon unit has been pulled because of heat buildup under the tail section. They now offer a stainless/black unit to take it's place...."

What is this issue with heat buildup under the tail?
