Once the HKS model is installed, the additional resinators are hidden behind the rear bumper. After buying the HKS model a few people told me they would rather spend the $700 difference on another mod but that decision is up to you. My next MOD is the GTM turn key FI system so intake, headers or a reflashed chip would be useless when a TT kit is installed. GET THE HKS MODEL AND YOU WONT BE DISSAPOINTED.
