I did install the Volant. Performance wise it is very close to the RotoFab. I live in Canada so with exchange the Volant is still pretty pricey. But much less than replacing the bottom part of the air box. The performance is good. The fit and finish is good. The pipe is super smooth on the inside, I was worried it wouldn’t be but it is. I wasn’t too worried about the look. I’m not showing my truck.
