This superbly fabricated piece
delivers Hahn RACE-quality CRAFTsmanship! The end
result of thousands of miles of testing in numerous
vehicles, we've brought you the downpipe that does it
right. The metal-matrix high-flow catalytic
converter is the last word in compact performance
converter technology. The effect on power is
minimal, typically about 5% as compared to our OffRoad
downpipe.
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 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.
Innovative SensorChamber
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 due to the
high-flow catalytic converter.

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!
