So I have these Z1 headers together with ART pipes (which should reduce the drone and rasp) coming and should be installed by next Friday. Currently I'm running stock headers with berks HFC and HKS hi power catback. I'll let u guys know how it sounds and if I feel a power diff when everything is said and done

Whats going to be interesting is the setup of ART pipes with HKS hi power as that will give FOUR helmholts resonators. Two at the the test pipes, two at the axle which is actually the same as running a full motordyne exhaust.
