AVO exhaust systems are constructed from CNC mandrel-bent TIG-welded stainless steel. Our systems are always designed for the straightest flow possible. They are designed to bolt up to the factory flanges, so that you can pick and choose which pieces you want to use throughout the entire exhaust system. New from AVO is our high-temp, high nickel content cast iron turbocharger outlets with divided collector for efficient exhaust extraction. Designed to survive the severe abuse of professional auto racing, this part will survive anything you can throw at it! The best feature of our cast outlets is that they are interchangeable with any of our downpipes. This means that if you change from a standard Subaru turbocharger to a twinscroll turbocharger, you will only need to get a new cast outlet, and can re-use the rest of your downpipe as is.
This system includes the AVO cast iron collector, stainless steel cat and full mandrel bent stainless steel piping all the way to the rear muffler.
