One can I was thinking of I might try is a carbon fibre one that I saw. Not sure where I saw it but it looked great.
The Diamond S piqued my interest but those cheap looking piece welds made it look like crap. That needs to be cleaned up in a big way. In a year that thing will even look worse.
This stuff saves weight but in fact may be causing a loss in HP.
Not sure Im willing to take a chance until I find one with the Ceramic Coating on the can.
Ive had this coating on on a 98 RMK and it still looks like new with no rust to be had anywhere.
It's a Silber Unit 6 ...I have one
No snow so no real tuning but sounds great on the stand
