This is why I went with this exhaust. With the stock NPP and Borla midpipe, for me valves closed only makes sense on cold or other starts in the neighborhood. But closed was too quiet to ever be in Tour or Sport while driving. I wanted a functioning after market NPP that makes a difference with the valves but also increases sound. I’ll have it installed tomorrow morning. Curious how the Borla will mate to this and what may be required.
