Combining GMG and JCR exhaust Systems on 991.2
Recently I installed a GMG Racing center bypass on my 991.2. The sound and tone is great, with some added mid-range torque as well. On the track, however, there is an intense resonance droney sound in my helmet coming out of some slow corners that makes you want to plug your ears up. Would JCR's side silencer bypass combined with our center bypass from GMG take out that drone? A louder car is fine with me, but I have a feeling that the drone is coming from all those built up gases inside the side silencer.

I currently have a SW bypass and about to add Soul for my side muffler delete. My current drone doesn't sound as bad as your but even if it was the weight savings and reduced heat on the tires is enough to say yes to the mod IMO.
