AVOTurboworld's New Gen 3 3" j-pipe for the 2014+ Forester XT is constructed from high-grade stainless steel, ensuring longevity and comes with ceramic coating 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 rear of the j-pipe reduces down in size so that it bolts to the factory intermediate pipe. A great addition to get rid of back pressure where the customer does not want to get rid of the majority of the standard OEM exhaust.
