Titanium 3in Catback Exhaust
The COBB Titanium Cat-Back Exhaust is unmatched in build quality, style, and performance. Utilizing Grade 4 titanium tubing, this cat-back offers high corrosion resistance and protection from impacts. Back purging ensures quality welds that will not fail due to contamination. The entire system uses slip-fit connections, allowing for a wide range of adjustments. Blued titanium tips add a distinct touch and offer adjustability. Best of all, this complete system weighs in at 24lbs assembled, nearly 50% lighter than its stainless steel counterpart.
- Grade 4 Titanium Construction with Back-Purged Welds
- Lightweight - 24lbs Assembled
- Blued Titanium Tips with COBB Logo
- High Adjustability via Slip-Fit Connections
- Bespoke Straight-Through Oval Muffler
GESI Catted 3in Downpipe
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 downstream 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 allow 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.
