This very nice downpipe from Invidia features a CAST divorced-wastegate collector. It features a divider to separate the wastegate passage from the main exhaust passage to reduce turbulence at the turbo.
This is the catless version of this downpipe, intended for race or other non-road use.
The downpipe can come with a built-in extra wideband oxygen sensor bung, so you don't have to have one welded on to your brand-new downpipe. Save money and time!
Regardless of your choices, you'll be getting one of the nicest downpipes made, with beautiful machining on the front and back flanges, fully polished 3" stainless steel pipe, and smooth mandrel bends.
NOTE: Whenever you modify your factory catalytic converter, you may end up with a "catalytic converter efficiency" check engine light (CEL) code. Use custom ECU tuning to remedy this issue.
Bolts up to most any cat-back that's designed to bolt up to a flat flange. NOT ideal for the stock cat-back, but could be made to fit with an adapter like this one.
Please read our FAQ page on catalytic converters before purchasing this part.
A rear gasket, nuts and bolts are included. The turbo-to-downpipe gasket is not included.
Fits all 2008-2014 WRX and 2008+ STI, including 2015+. Also fits manual-transmission Legacy GT and Outback XT, model years 2005-2009.
