No worries with carbon on the SV. its only when you start getting to the litre twins you get issues. If its what you want then go for it. All exhausts are much of a muchness in all honesty. 1-3hp here or there. They all make the same noise, they all look better than the std can, and anything to get rid of that Blueflame rubbish of your bike
Go for it id say
Treacle had issues with his Arrow system splitting on his SVThou!
