AVOTurboworld's New Gen 3 3” Twin Scroll downpipe or front pipe for the VF36/V37 turbocharger was designed with the intention of optimum gas flow and minimal exhaust back pressure which is essential for high power. Careful attention to tube diameter, smooth radius mandrel bends and a large cat converter body 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. The optimum internal profiles cannot be achieved with twin pipes. 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 with a 5” body 160 cell metal cat converter. The reason for the 5” body is that it flows better than the 4” body when flowing both with comparable cells. The bigger the area within reason the more flow it will have. You might ask why 160 cell and not 100 cell like some of the aftermarket front pipes available on the market, we know that it will help with the maintenance of emissions control. The 160 cell cat converter is also a compromise between maintaining high performance and some emission control.
AVO have also manufactured the front pipe with a factory OEM style flex as it is required to work with 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.
