A3
8L 1.8T
APR's A3 catback exhaust is a stainless steel, mandrel bent system.
Our exhaust begins after the factory catalytic converter with
a with a 2.5" center pipe which contains a small 3"
resonator. The 2.5" pipe continues back to the muffler and
two stealth downturn tips. With TIG welding, fully stainless construction,
and CNC'ed hangers, you will not find a higher quality system
on the market.
A3
2.0T Exhaust
APR's A3 Exhaust is a stainless steel, 3.0" mandrel bent,
turbo-back exhaust. Unlike most other aftermarket exhausts, the
APR exhaust is a full exhuast from the turbocharger back. This
exhaust is very quiet and simply changes the tone of the exhaust
to a deep, unobtrusive sound. With TIG welding, fully stainless
construction, and CNC'ed hangers, you will not find a higher quality
system on the market. All APR exhausts come with a full lifetime
warranty.
On the A3, the stock exhuast is almost 2.5" and flows very
well even on a chipped car. Simply adding an exhaust to a stock
or chipped 2.0T does not make a very big gain over the stock setup.
Unlike the 1.8T, because of the new engine management (ME9) and
FSI, there are substantial gains that can be seen by making a
software change after adding the exhaust.
With APR exhaust-specific software, peak gains of 18hp and 20lb-ft
can be seen. At some RPM's, these gains are as high as 22hp and
25lb-ft. APR exhaust-specific software is available for free for
all APR ECU Upgrade customers.
APR is in the process of forming a complete line of exhaust upgrades
for all variations of the A3. Whether for street or track use
we will have the right application for you!
TT 1.8T Cat Back
APR's TT Exhaust is a stainless steel, mandrel bent, cat-back

gives it a deep snarl that a sports car of the TT's caliper deserves.
With TIG welding, fully stainless construction, and CNC'ed hangers,
you will not find a higher quality system on the market. If you
have a 180hp TT, you will need to get the rear lower valence for

Audi
S3 / A3 2.0T Quattro 3” Full System
APR Australia is proud to announce the release of the new full
exhaust system upgrade for the A3 / S3 2.0T. The new exhaust system
is a 3" stainless steel construction system, with the use
of high quality mufflers high flow catalytic converter and stainless
twin wall tips. The system uses laser-cut brackets to ensure a
perfect fit for your Audi.
This exhaust system features a unique separate wastegate dump
pipe - which redirects exhaust from the wastegate further back
the downpipe. The result is much less turbulence at the exit of
the turbo, allowing exhaust gas to flow even more freely.
The exhaust system increased 12kw at the wheels on our development
vehicle (A3 2.0T Quattro). Even more impressive, our test vehicle
reached peak boost pressure 800rpm earlier in the revrange. This
will result in much better throttle response, stronger torque
delivery in low and mid range and of course, additional peak power.
APR's exhaust-specific software is available free of charge to
existing APR software customers. This exhaust will benefit the
cars fitted with the larger K04 turbocharger even more. Note:
because of the high flow catalyst, you may require software that
allows for the higher flow - please check with your APR dealer
if you do not have APR software installed.
