if i were you i would look into doing a custom single. you can choose your muffler look/volume and add a resonator or two. i dont think im ever going to purchase an aftermarket catback exhaust, i loved my custom borla’s and the sound/power/look options you get from a custom are far superior to whatever JDM engineers think up at HKS/greddy/amuse/whatever. plus with the great local shops we have it will probably be cheaper :lol
