this is MAINLY towards people with HKS Hiper Carbon-ti but anyone can feel free to add input. i was wondering if other peoples' exhausts were relatively silent when they FIRST turn on their engine. my exhaust sounds a LITTLE bit deeper than stock right when i turn on my engine and i have to wait til my engine temp is in the middle in order for my exhaust note to hit its ideal volume. is this only for the Hiper Carbon-ti or do other exhaust go through this. thanks in advance for input.
