well instead of starting a new thread going to bump this one.
at the moment my car ebc @ 10psi, r34 smic, 3" cat back, pod.
i'm going to get it tuned soon and was wondering if it will be worth finishing my exhaust.
like how much power difference will it make after the tune having the dump/front and not having it?
and an upgrade of turbo in the future has not been ruled out
thanks
