Hi mate, noticed you're in Australia too and have a boxster with the gemballa exhaust. Would like to know if it drones and if its too loud for daily use such as cruising at 60-80km/hr and on the freeway at 100km/hr or more? Recently installed a stebro race exhaust and bloody hell it was so loud, drony and ear deafening it was ridiculous and wanted to get it uninstalled within 50m down the road after driving away from the workshop. Anyway, the workshop has offered me a deal on their last in stock gemballa exhuast and woul dlike to know how they are before I go dumping a wad of cash on it and I'm not happy with it and can't take my daughter or wife in the car. You're assistance would be very much appreciated mate. By the way, how much did you pay for your gemballa exhaust? I'm in Victoria. Where are you located?
