When shopping for a downpipe, you know that COBB Tuning is a brand you can trust. They are pioneers of the game especially when it comes to making horsepower out of a Subaru. This is a CAD designed bellmouth downpipe that is equipped with a single high flow catalytic converter. Basically this allows for much better air flow than the factory unit, and combined with COBB’s Accessport makes for an easy an efficient means of making horsepower.

These downpipes feature 304 stainless steel construction, and has the factory style location for the 02 sensor provision. The actual catalytic converter is fabricated out of 400 grade stainless steel that has a much higher flow rate and a longer lifespan compared to ceramic or “brick” style cats. This reaches a faster operating temperature with cleaner cold-start emissions. There will also be a second 02 sensor provision for the other 02 sensor.

Finally this is 3” in diameter for piping size, however it does taper to a 2.5” stock flange. And this downpipe is compatible with any cat-back exhaust that mates to the factory cat section.
