From the legendary Korean exhaust manufacturer, Jun B.L, they introduce their turbo downpipe with integrated catalyst cell (aka catted). Perfect fitment on any 2013+ Veloster Turbo and the highest quality available. This part bolts directly to the turbo and attaches to the middle pipe from the exhaust system - utilizes 2.5" piping through the entire exhaust system for a proper air flow from the turbo all the way to exit.
