Hahn Chevy Cobalt SS/TC 2008-10 Max Flow Off Road Downpipe
This superbly fabricated piece delivers Hahn RACE quality CRAFTsmanhip!
The end result of thousands of miles of testing in numerous vehicles,
weve brought you the downpipe that does it right.
Continuous Mandrel Bending
Smooth, wrinkle-free bends for maximum flow. Our sophisticated in-house Mandrel Bending provides a clean, quality result, superior in appearance AND function to pipes formed by welding together miscellaneous chunks of tube. No unsightly welds to rust and impede flow.
Ultra-Strong Flex Section
You wont see flex section failures on Hahn downpipes. Our high-quality stainless steel flex design has evolved from years of experience and thousands of downpipes weve produced. It features an exclusive three-layer design for maximum flexibility combined with optimal durability.
Innovative SensorChamber
Heres where we really nailed it. Our new SensorChamber creates a perfect environment for the downstream O2 sensor. Innovative design and extensive testing has proved that the SensorChamber prevents diagnostic trouble codes (DTCs), and will not set the Check Engine Light (CEL). You wont have to worry about random CELs popping up from the lack of a catalytic converter. This makes your race days (this downpipe is intended for off-road use only) just that much more fun!
A note on 02 sensor placement...
Your cars O2 sensors are super-sensitive, and amazingly advanced little pieces of technology. Without them, wed not be able to generate todays superb levels of fuel mileage and power. But they cant just be shoved in the exhaust anywhere! The delicate sensor element within is subject to damage if the sensor position is not inherently self-draining. As illustrated in the diagram above, the sensor must be mounted so that it can drain, in an upper position between 9 and 3 oclock. If the sensor is installed in the pipe in a position that does not allow it to drain water condensate and particulate matter, the sensors accuracy, and ultimately its lifespan, will be adversely affected. Non-draining O2 sensor positions between 3 and 9 oclock are where the problems begin. Beware of amateurish pipe designs that do not take this into consideration!
Notes:
3" s/steel TIG-welded construction, heavy-duty mutliwall flex section, SensorChamber equipped; off-road use only
