Similar Vandemon exhaust issue...

Hey all! Saw a similar post as to my issue. I am having abnormal heat wear on the Vandemon can. As you can see in the pics, the actual end can is wearing on the bottom and then it’s like the gasses hit the outer top part of the can before they exit. I have it tuned with the FTECU and intake as well but I’m only getting 214whp. We couldn’t figure out why it’s not higher but maybe the exhaust restriction may be cutting into that. Just curious of your thoughts!

There's the other post on here about the vandemon catching fire and spitting material big time.Maybe call Vandemon and tell em what's goin on....they totally replaced the other guy's.This would be two now that aren't performing correctly.That we know of.Probably a bunch more.Somethin's goin on with their production process me thinks.

Thatís not good, I guess you need to contact them, explain and send images.
Recent events on the forum arenít a great advert for Vandemon...

I went ahead and sent them an email. I was just curious if anyone else had a similar problem. And if you all think that may be why my WHP was lower than expected as well..

Wonder how these are getting through inspection and quality control at vandemon, or maybe lack there of.

Hey sup buddy
Saw the abnormal
Heat wear your talking about in pic
The muffler is turning coats of blue n purple like the intake pipes.

As for ur tune the muffler having abnormal wear shouldn’t impact it in the least. Stock my bike had 208 to wheel it’s 2019 but still ur 214rwhp is ridiculously low
After a flash n exhaust n filter without a tune mines making 239 rwhp. Something is going on with ur flash it’s not correct and it’s still restrictive on the fuel map.
If u have a dyno graph it would help
And
If you have a throttle % graph at each rpm that would be even better

Woolich and ghul are the usual flashes for ecu
I’m personally going woolich
