Bonjour,
Steve, I know you tend to favour secondary "G" (or "J") pipes over primary/Cup bypass pipes, for most of us, who drive our 911's on the road.
This enquiry pertains to your prefered choice, if you had to choose between a cat bypass and a "G" pipe?
My concern for some trackday use, both near and far (eg UK), is that with both in place, I would exceed local static and drive-by noise tests.
Any thoughts?
Best ~
