Got hot. I burnt up two CF cans on my sportbike riding the highway wide open. First one burnt kind of like that amd cracked in 10 bajillion places, second one fricken was literally roasted. Once i rejetted and made it more rich for highway speeds i didnt burn another one up. If they dont take it back, cut the CF off and rewrap it in stainless or something
I have run the carbon fiber can for about 3 or 4 seasons in the mtns. Full throttle pinned to the bars for minutes at a time
in long climbs. My engine is a 600 carb big bored to 621 and ported and head work. Likely making very similar HP to the etec.
No problems at all with it.
Do seem to remember something about 600 etec's with stock pipes and cans having extremly hot exhaust, glowing red even. Not all, just occasional one with a problem. That might have been just a few early ones.
