AVO Downpipe WRX STI 2008-2009
Product Description
AVO 3" stainless steel downpipe for 2008 WRX features a special cast iron outlet and a high flow metal cat. The outlet incorporates a splitter to deflect wastegate gases for improved turbo spool up and exhaust flow. The stainless steel high flow race catalytic converter provides maximum power and longevity.
The high-temp cast outlet also improves turbo performance with its ability to retain heat, superior to CNC stainless steel designs. Heat retention is important to turbo performance, and AVO cast outlet helps prevent turbo housing cracks by helping to absorb rapid temperature changes in material.
A new feature of an AVO downwpipe is a high-temp, high nickel content cast iron turbo outlet with divided collector for efficient exhaust extraction. Designed to survive the severe abuse of professional auto racing, this part will survive anything you can throw at it! The best feature of the AVO cast outlet is that they are interchangeable with the lower downpipes. This means that if you change from a standard Subaru turbocharger to a twinscroll turbocharger, you will only need to get a new cast outlet.
Best downpipe on the market.
Note: Manual trans only. To special order an downpipe for 5EAT Automatic. Please leave us a note in the shopping cart, or call us @ 1.888.773.1212
