How about HKS exhaust?
is it that bad that no one is really talking about it?
I prefer FI over stillen for everything but how about HKS?
I am trying to decide betwwen HKS or FI
how long is it gonna take to get an FI as it is made by order?
I know the carbon fiber is for weight saving but what is the resonator for？
can anyone tell me what is the resonator for and how is it works?
is the resonator gonna help with power? or just making it louder?
sorry for so many questions.
Thanks.
