About the Mk5 R32 Style Catback Exhaust
Our Mk5 R32 Style Catback Exhaust has all of the features that made our Mk5 GTI/GLI Exhaust Systems such a success: Great looks, perfect fitment, dyno proven gains and an amazing sound!
To install our R32 style catback, you must also have the OEM R32 Rear Bumper installed. These are readily available at your local dealer. If you would like a list of these parts, please contact us.
This catback system is topped off with our signature 3.5" beveled exhaust tips, available in Polished Silver or Diamond Black finishes. The tips sport crisp A.W.E. Tuning logos and are double walled to ensure no discoloration even under hard usage. The system has multiple slip joints with high quality t-bolt clamps, to allow optimal adjustment.
Our catback system will mate up to the stock downpipe or any other downpipe that is designed to mate to the factory catback exhaust.
Here are some features of our system. Each feature was chosen for performance and longevity reasons, and when making your exhaust decisions you should settle for nothing less:
The MK5 R32 Style Bumper conversion kit is available upon request for an additional $795.00
The MK5 R32 Style Bumper conversion kit is an OEM factory part combination that makes the addition of the AWE Tuning R32 Style Exhaust a no brainer. It's the same kit used on our AWE Tuning Time Attack winning MK5 GTI, and offers a perfect, OE look that brings out the AWE Tuning R32-Style Exhaust perfectly.
Included in this kit is:
The kit will allow you to simply build out your MK5 with the center dual-tip look, simply, easily and cleanly.

Why did we choose 2.5 inch and not 3.0 inch diameter for our MK5 exhaust? Our first prototypes of this system were indeed 3.0 inch, but we found that the effort it took to move the large mass of air in the 3.0 inch system at lower rpms resulted in a loss of torque with very little offsetting gain up top. Take a look at our 3.0 inch prototype dyno sheets and see why a 3.0 inch system is not appropriate for this car.

AWE Tuning 2.0T Exhaust Dyno Tests
Below are comparision dyno tests as performed on our Mustang MD-500-SE AWD dyno.
All tests were performed on the same car, with controlled ambient conditions. Each test is average of 3 runs performed.
Cat Back Exhaust Testing
Our first prototype for the A3/GTI/GLI was a 3" diameter cat back system. Careful before and after dyno testing showed that for this car, bigger was definitely not better. The air mass found inside the 3" tubing proved to be a restriction to the engine until the higher rpm region, and even at that point gains were minimal. Our reputation is to bring only proven products to market, and a 3" system is definitely not the wise choice for power on this car. Design was rejected.
After further dyno testing, we found that a 2.50" diameter gave the best overall balance of torque and horsepower gains. Peak gain were 3.1whp and 0.1wtq.
In the graphed gains sheet below you'll find the measured differences between baseline and test in dyno sheet of AWE Tuning 2.50" Cat Back Dyno Test vs stock exhaust. The AWE Tuning 2.50" exhaust produces a maximum increase of 4 wheel hp at 5300 rpms and 28 wheel torque at 2400 rpms vs. the stock exhaust. Overall, gains are seen over practically the entire powerband.

Turbo Back Exhaust Testing
In the interest of accurate data, we conducted careful tests with our downpipe design. As we saw with our cat back testing, a 3" inch design is absolutely too large for this vehicle. We even tested with an aggressive G.I.A.C. X-Chip installed in the vehicle, to simulate the kind of power levels that most people will choose for their vehicle. Even with the extra power of the performance chip, 3" diameter tubing was too much air mass for the engine to move, resulting in a clear disadvantage compared to the 2.50" turbo back design.
Intake temps were closely monitored for the test. It is extremely difficult to obtain exactly the same test conditions run after run, and we found that the 3" tests were done with a slightly cooler intake air temp. Even with this advantage, the 3" design could not make as much power at the 2.50". Identical cell count cats were used for both tests, and the same chip file was in the vehicle for both tests. The tests were done on the same day and on the same car, just as they were with the cat back tests above.
2.50" diameter gives the best overall balance of torque and horsepower gains. Peak gains for the 2.50" system were ~20 crank hp and 14 ftlbs crank torque over the stock turbo back exhaust, while the 3" system could only muster ~9 crank hp and 1.5 ftlbs crank torque over the stock turbo back exhaust. There was no debate on what diameter worked better at this power level.
