I just wanted to inform everyone that the Gt Spec underbrace will clear the HKS TI exhaust. Everything went according to plan without any problems. As far as noticing any structural difference, I was unable to tell. I don't know if it is becuase I already have cusco sway bars, D2 coilovers, and front and rear tie bars(also GT Spec). I guess it's nice to have just in case.

 

thanks for letting us know, glad it worked for you
