AVOTurboworld's New Gen 3 3” Single Scroll race pipe or catless front pipe was designed for the race car enthusiast. Careful attention to tube diameter and smooth radius mandrel bends is essential for high performance. With 29 years of experience in exhaust system design, the AVO system is a superb exhaust system with plenty of thought and care.
The AVO front pipe has a separate cast section that increases the wastegate and exhaust flow over the standard OEM version. The design parameters immediately after the turbocharger are critical not only for outright performance, but for optimum torque and turbo response. It is cast in high temperature ductile iron which ensures optimum internal shape and maximum durability under high rpm, load and boost conditions. The stainless pipe section after the cast outlet is 3” mandrel bent.
AVO have also manufactured the front pipe with a factory OEM style flex as it is required to work with the factory OEM cat back exhaust. Without the donut gasket and OEM spring loaded bolt setup then your headers and any welds forward of the flex are prone to cracking. The stainless flanges are a lost wax stainless casting that are 13mm thick and will not warp under the harshest of conditions. The thickness of our exhaust tube is 1.5mm which is thicker than most aftermarket front pipes. This helps with noise absorption and with longevity of the product.
With the AVO product you are guaranteed a product that will truly deliver all it promises.
