What if we were to delete #7 and #8? And why did you install an X-pipe instead of just straight pipes?I recently had the #7 (resonator) removed and replaced with an X-Pipe. Every thing else remaining consistent with how my 2017 Sport V-8 was delivered.
My opinion ...not much of a difference (in sound) unless in dynamic sport mode using the manual functions with compression and higher RPM. In standard drive exhaust sounds as it came delivered from the dealer (to me anyway).
There is a notable audible change in exhaust when starting the car... a "throater" sound in idle.
