hey i have a turboback full 3inch TBXS exhaust uninstalled. I have HKS turboback also. i am wondering which one will yield better resultswith the xede the 3 inch or the 2.75 HKS setup. So i know which one to sell

 

??? We really havent done a strict back to back of those two exhausts if all things equal the 3" should perform better if its not some weirdo design

 

LOL oh ok. Doesnt look ilke a weirdo design LOL. I guess ill keep the TBXS and sell the HKS since the HKS is not a true 3 inch
