Djaniero Posted May 18, 2018 Share Posted May 18, 2018 Hi Guys, Random one, but hoping some of you gurus might help. I recently bought an Autofixed Turbo-Back exhaust system (For the noobs, a trader on the forum used to custom make them back in the day...awesome exhaust imo), but the backbox baffles need repairing as you can hear them moving around inside when you shake the backbox, Anyway, after speaking to a couple of fabricators, they have suggested to just replace the backbox with a new one, instead of repairing my old one. But my concern is, if I do this, that the exhaust may not sound the same :(. At the moment, the exhaust is 2.5inch straight through with no resonators and a japstyle can with a 3inch tip. Strangely enough it isn't loud at all, sounds perfect. Nice burble on idle, no drone when cruising around and not intrusively loud when on boost. On the other hand, the hks Hi power style system currently fitted to the car with a resonator is louder than my autofixed system, and does drone a bit when cruising and when on boost. Can anyone explain to me how the HKS system is louder than the autofixed system, if it has a resonator where as the autofixed is straight through? Quote Link to post Share on other sites
