Hey guys just started dc2 this morning and it sounded different, it sounds more deeper and "fartier". My B18B2 has no modifications to it and the exhaust system hasn't been touched snce it was made and there are no holes on the pipes. Could it be tme to replace the muffler?
I recorded how it sounds. It sounds worst in person.
