Rottweiler Performance is excited to release an item for the DIY enthusiasts who like to take a custom approach to exhaust systems. These beautifully machined flanges are made out of 304 Stainless Steel that is highly resistant to corrosion. 304 Stainless steel is also far less thermally conductive than carbon steel which means less heat absorption. Rottweiler Performance has taken a step further by machining in a recess to help capture the tubing that is put in place. This will be absolutely the best starting point for your custom exhaust!
