W213 E63s Exhaust
Just wondering lately - I have a 18' E63s with the performance exhaust and it is substantially quieter both in car and out of the car than my 21' GLC63s. Valves open in Sport + obviously.
Whats the deal? The GLC63s in comfort mode is louder than the E63s in Sport + which is weird.
Might be a stupid question but Im just curious.
