Features:
The COBB Tuning GESi Catted 3" Downpipe begins with a CAD designed cast bellmouth that smoothly blends air exiting the turbocharger's turbine housing. Minimizing turbulence when exhaust gasses from the wastegate join into those flowing through the turbine helps to prevent excessive back-pressure. The cast housing is capped off with a COBB logo and auxiliary O2 bung for those wanting to install a wideband sensor early in the exhaust path.
A welded bracket utilizes the factory hard mount near the transmission reducing stress on the turbocharger mounting bolts and studs.
Corrosion resistant and mandrel bent 3" 304 Stainless Steel tubing carries exhaust gasses down stream into a COBB-exclusive GESi 300 cell high flow catalytic converter. A second O2 bung is located directly after the catalytic converter and is to be used by the OEM Rear O2 sensor.
A CAD designed, cast 304 stainless steel, flange finishes off the tail section of the downpipe. The reinforced cast flange is less susceptible to warp during assembly and for those of you installing with the strength of Hulk. A stainless adapter flange and included MLS gasket allows direct fit with the factory exhaust or COBB Cat-Back Exhaust utilizing the OEM donut gasket. Included COBB proprietary shoulder nuts allow installation of the factory spring bolts without fuss.
Works great awesome quality.
Product was packaged well and the quality is great. Make sure you buy a new gasket from the turbo to the downpipe as Cobb does not supply one. These also to not neck down to 2.5 like the old design.
Fit and finish was excellent. I would expect nothing less from Cobb. Install wasn't bad just a little time consuming 3 hours. Comes with a gasket from downpipe to Catback. I recommend getting a new turbo to downpipe gasket.
great product
I order this down pipe and the aem fuel pump and got it supper fast in the same box. The down pipe was wrapped nice for shipping. The down pipe fit no problem and has amazing welds on it. I will be coming here to buy my parts from now on.
Cobb always makes a quality product and this is no exception, however on my 2010 STi it was not a direct fitment. The downstream bung was about 8 inches too far past the oem the location, likewise with the hangar. Not sure why they did this because on past models the bung was located in the correct spot. Very nice product that sounds awesome but frustrating fitment from one the most expensive downpipes available.
Got my order Way faster than expected!!
