Do Your GHLs Resonate At All?

I don't know about GHL, but the stock 987S exhaust has resonance between 55-60mph when cruising in 6th gear. Quite annoying, makes me drive at 70 mph on looong trips since it gets rid of the resonance. Curious in a way, 'cuz the C4S with PSE has NO resonance at all.

It has some resonance form 2.5k-3k. Its not annoying, but very aggressive IMO. I think if you want an exhaust note with a lot sound, there's going to be some resonance. Again it doesn't sound like rattling cans, just like it means business. This is all for the 986S. I guess you will be the first with a GHL on a 987S. On a side note, I heard the 996 GHL mufflers are kind of quiet, no resonance at all.
