Cobalt SS/TC MODpipe


Cat Con Option shown

Cut-Out Option shown

The MODpipe Modular Downpipe is simply the most versatile exhaust component available for your Cobalt TC.  It features three easily replaceable modular sections to give you nearly limitless options now, or in the future.  V-band clamps are used at precision, gasket-free connections for ease of installation.

Run a cat on the street, and then swap in a straight pipe for the track.  Want to make some noise?  Try the electric cut-out!  Upgrade your turbo later?  Just replace the head section! Swap sections easily using the V-band clamps included. 

Start with the Base Kit, which already contains the Stock Head Section, Rear Section, and two V-band clamps.  Then add the Mid Section option you want for a complete installation.

Head Section Options: featuring our Ultra-Strong Flex

You won't see flex section failures on Hahn downpipes.  Our high-quality stainless steel flex design has evolved from years of experience and thousands of downpipes we've produced.  It features an exclusive three-layer design for maximum flexibility combined with optimal durability.

The MODpipe Base Kit includes the H EX-6182 Head Section, which is also available separately.

These replaceable Head Sections allow you to start with a stock turbo now, then convert to a larger turbo later (these other Head Section options for larger turbos will be available soon).  All you'll need to do is just change out the Head need for a new downpipe when you upgrade that turbo!

Rear Section: featuring our innovative SensorChamber

Every installation will use this Rear Section.  It's included in the H EX-6181 Base Kit, and also available separately.

Here's 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 (DTC's), and will not set the Check Engine Light (CEL).  You won't have to worry about random CEL's 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 car's O2 sensors are super-sensitive, and amazingly advanced little pieces of technology.  Without them, we'd not be able to generate today's superb levels of fuel mileage and power.  But they can't 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 o'clock.  If the sensor is installed in the pipe in a position that does not allow it to drain water condensate and particulate matter, the sensor's accuracy, and ultimately its lifespan, will be adversely affected.  Non-draining O2 sensor positions between 3 and 9 o'clock are where the problems begin.  Beware of amateurish pipe designs that do not take this into consideration!
