I wen't with the Lachute headers and up-pipe combo. All I wanted was more power and I do have a turboback. I wen't from 319hp to 361hp.kirch a écrit :veerrryyyy nice!
Why have you decided to change your headers rights away? Is there a significant gain in performance? What is the brand you chose? Too bad you didnt have the full tbe and THEN install headers... I'm curious how big of a difference it does in terms of sound-loudness on an STI.
