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 Section...no 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!
