Description

The ISR Performance Single GT exhaust is a y-pipe back exhaust system made of mandrel-bent stainless steel. It is designed to provide unrestricted flow for maximum horsepower while retaining a deep and aggressive exhaust tone. This single GT exhaust is suitable for both naturally aspirated and forced induction applications. It includes a flange adapter for compatibility with a stock Y-pipe.
