GL63 vs GLS63 - Exhaust Sound
Anyone have first hand experience of the exhaust noise on the GL63 and now on the GLS63, is the newer version louder, different etc?
I thought I saw somewhere that the GLE63 has an active exhaust option, just interested to know about the various noises from these M157 emgines without an aftermarket change out?
Will a tune change the note on these?
Thanks
Carl
