Hi guys,
Im after a new exhaust system for my car , the one on it is way to quiet
so i figure it must be very restrictive. Car is a R32 GTST with a HKS GT2540 turbo, what size and setup do you guys recommend?
Atm it has a 2.5 system , with CAT and a HKS muffler. This thing is so quiet i cant hear shit but induction noise and the engine.
