The AVO Down Pipe (or Front Pipe) is constructed from high-grade stainless steel, ensuring longevity along with great looks. It also features our special cast iron outlet which incorporates a splitter to deflect wastegate gases thereby improving turbo spool up.Together with our High flow C.A.R.B-approved catalytic converter we now offer the worlds most potent Legacy GT Turbo downpipe combination. The high-temp cast outlet removes a major bottleneck present on the factory exhaust system with it's large bellmouth design with splitter for the wastegate. A stock exhaust flange simply has a blank plate at the wastegate, putting a major lid on performance.Your stock down pipe also uses one or two fairly restrictive catalytic converter(s). The AVO front pipe addresses this issue with a single high-flow sports catalytic converter. All this adds up to a huge decrease in back pressure and a big increase in performance. Use your turbo to it's full potential!This down pipe fits USDM Domestic Market 5 & 6 Speed Manual Transmission models Legacy GT 04+, Spec B, & Outback XT.
