This 3inch downpipe (or Frontpipe) 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 its 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 large high-flow sports 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. Use your turbo to its full potential!
