AVOTurboworld's New Gen 3 3" front pipe kit for the 2014+ Levorg GT-S manual transmission is constructed from high-grade stainless steel, ensuring longevity and comes with a ceramic coated j-pipe as well to keep under bonnet temperatures down. Your factory OEM j-pipe also uses a fairly restrictive front catalytic converter. The AVO j-pipe addresses this issue with a single large 5" body high-flow metal catalytic converter, larger than available from most other makers. All this adds up to a huge decrease in back pressure and a big increase in performance due to volume. The intermediate pipe section after the j-pipe is 3” mandrel bent with the transmission mounting bracket. AVO have also manufactured a OEM style flex setup as it is required to fit with the factory OEM cat back exhaust. Without the donut gasket and OEM spring loaded bolts, 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.
