The Ultimate Guide to Installing an AWE Touring Edition Exhaust on the Audi RS5 2.9TT

Upgrading the exhaust system on a 2018-2022 Audi RS5 with the 2.9-liter twin-turbo V6 is one of the most popular modifications among owners seeking a sharper sound and a modest performance gain. The AWE Touring Edition Exhaust stands out as a refined, daily-driver-friendly option that balances aggressive tone with minimal drone. This article provides a detailed breakdown of the benefits, costs, installation process, and real-world considerations for this exhaust system. Whether you are a seasoned DIY mechanic or planning a professional install, you will find everything you need to know to make an informed decision.

What the AWE Touring Edition Exhaust Offers

AWE Tuning has a strong reputation in the European tuning space, particularly for Audi and BMW platforms. The Touring Edition exhaust is designed specifically for the RS5 2.9TT to enhance the driving experience without overwhelming the cabin. It uses 2.75-inch mandrel-bent tubing, precision TIG welding, and features AWE’s patented “Drone Elimination” technology (180-degree technology) that cancels problematic frequencies. The system is fully cat-back, meaning it replaces everything from the catalytic converters back to the tips, and it is available with a choice of diamond black or chrome silver tips in 102mm or 115mm sizes.

Unlike some aftermarket exhausts that are purely loud, the Touring Edition aims for a deep, purposeful growl at idle and a full-throated howl under wide-open throttle. It is noticeably louder than stock but remains civilized during highway cruising, making it a strong choice for a daily driver that occasionally sees track time.

Key Benefits of the AWE Touring Edition Exhaust

1. Improved Sound Quality

The stock RS5 exhaust is surprisingly muted, partly due to strict Euro emissions and noise regulations. The AWE Touring Edition unleashes the raw character of the 2.9TT engine. Cold starts produce a pronounced bark that quickly settles into a muscular idle. Under acceleration, the exhaust delivers a rich V6 warble with no raspy overtones, and the addition of the optional non-resonated mid-pipes (for those wanting even more aggression) can transform the tone further. Inside the cabin, drone is nearly eliminated thanks to the 180-degree technology, keeping conversations and music clear at 70+ mph.

2. Modest Performance Increase

While the factory exhaust is already relatively free-flowing for OEM, the AWE system improves exhaust gas velocity and reduces backpressure. On the dyno, owners typically see gains of 8–12 horsepower and 10–15 lb-ft of torque at the wheels on a stock car. These numbers can be slightly higher when combined with a stage 1 ECU tune. More importantly, the power delivery feels crisper and more responsive, particularly in the mid-range. The weight savings (roughly 15–20 pounds depending on tip selection) also contribute to improved handling and quicker throttle response.

3. Premium Build Quality

AWE uses CNC mandrel bending to ensure smooth, consistent bends that maximize flow and eliminate stress points. The TIG welding is clean and uniform, and the entire system is CNC-formed from high-grade 304L stainless steel. The clamps and hardware are also stainless steel to resist corrosion. This level of craftsmanship means the exhaust will hold up well to winter road salt and track heat cycles without showing premature rust or discoloration. The attention to detail extends to the exhaust tips, which feature a double-walled design to keep the outer surface cooler and minimize blueing.

4. Retained OEM-Quality Fitment

One of the biggest frustrations with aftermarket exhausts is poor alignment or contact with the underbody. AWE designs all its exhausts in-house using 3D scanning and test fittings on actual vehicles. The result is a direct bolt-on system that requires no cutting, welding, or drilling. All hanger positions match exactly with factory rubber isolators, and the tips can be adjusted for depth and angle before final tightening. Owners consistently report that the system fits as well as (or better than) the factory unit.

5. Customisable Options

AWE offers the Touring Edition with two sound profiles: the “Resonated” version (standard) and the “Non-Resonated” version via optional mid-pipes. The resonated uses internal sound-absorbing materials to tame harsh frequencies, while the non-resonated delivers an even more aggressive tone. Additionally, you can choose between two tip styles (diamond black or chrome silver) and two sizes (102mm or 115mm), allowing you to match the look of your car precisely.

Cost Breakdown: Parts, Labor, and Total Investment

The total cost to install an AWE Touring Edition Exhaust on an Audi RS5 2.9TT is approximately $2,000, though the exact amount depends on your tip choices and labor rates. Here is a detailed breakdown:

Exhaust System Cost

  • Standard resonated system (with 102mm tips): $1,495 – $1,595 depending on retailer pricing and sales.
  • Upsize to 115mm tips: Add $100–$150.
  • Chrome silver vs. diamond black tips: Usually the same price, but some finishes vary by $50.
  • Non-resonated mid-pipes (optional): Add $300–$350 if purchased at the same time.

Most buyers spend around $1,600 to $1,750 for the base system plus shipping. Always purchase from an authorized AWE dealer to ensure warranty coverage.

Installation Labor

Professional installation typically ranges from $300 to $500. The RS5 exhaust is relatively straightforward to remove and install, but a good shop will lift the car, use proper tools, check for alignment, and test for leaks after installation. Rates vary by region: major metro areas or luxury performance shops may charge $150–$200 per hour, while independent import specialists might charge $100–$140 per hour. Most installations take 1.5 to 2.5 hours.

Additional Parts and Sundries

  • Hanger removal tool: $10–$20 if you don’t have one (can buy or borrow).
  • O2 sensor-safe lubricant: $10 (helps prevent seized bolts).
  • Replacement gaskets: The AWE system reuse stock gaskets, but if they are damaged during removal, budget $20–$40 for new OEM seals.
  • Shipping charges: Varies – often $20–$50 for standard ground in the U.S.

Total estimated investment: $1,900 to $2,200 (parts + labor). Our $2,000 approximation is a solid midpoint for a standard resonated system with professional install and standard tips.

Installation Process: DIY vs Professional

The installation of the AWE Touring Edition Exhaust is a moderate-level DIY job. If you have basic mechanical skills and a metric socket set, you can complete it in a driveway with jack stands. Below is the step-by-step process for those who choose the DIY route.

Tools Required

  • 3-ton jack and jack stands (or a lift)
  • Metric socket set: 13mm, 15mm, 18mm (for hanger bolts), 10mm (for small brackets)
  • Ratchet, extension, and universal joint
  • WD-40 or penetrating oil (soak bolts 24 hours ahead if possible)
  • Safety glasses and gloves
  • Hanger removal tool (or a large flathead screwdriver and pliers)

Step 1: Preparation and Safety

Ensure the car is cold. Park on a level surface, chock the wheels, and lift the rear of the vehicle high enough to work comfortably. Place jack stands at the designated lift points. Never rely solely on a hydraulic jack.

Step 2: Remove the Stock Exhaust

Start by loosening the two V-band clamps connecting the rear muffler section to the mid-pipe. These are located near the axle. Then unbolt the hangers from the rubber isolators using the hanger removal tool. There are four hanger points: two on the muffler and two on the mid-pipe. Slide the muffler section off the hangers and lower it. Next, remove the mid-pipe by unbolting the flange connection just behind the catalytic converters (two 13mm bolts). The entire OEM assembly is heavy and can be maneuvered out from under the car in two pieces. Be mindful of the heat shields – you do not need to remove them.

Step 3: Transfer Hardware and Prepare the AWE System

Inspect the OE gaskets at the mid-pipe connection; if they are in good condition, reuse them. Otherwise, replace. For the AWE system, the muffler and mid-pipe come preassembled. Slide the included clamps loosely onto the tubing (do not tighten yet). Fit each hanger into its corresponding isolator. Use a rubber-safe lubricant to ease installation if needed.

Step 4: Install the AWE Exhaust

Hang the rear muffler section first, then the mid-pipe. Ensure the V-band clamps are aligned and snug but not fully tightened. Adjust the tip positioning: the 115mm tips in particular need careful alignment to center in the bumper cutouts. Once the tips are exactly where you want them, tighten all clamps and hanger bolts to the torque specified in the instructions (typically 25–30 Nm for V-band clamps, 15–18 Nm for hanger bolts).

Step 5: Leak Check and Final Torque

Lower the car and start the engine. Listen for any hissing or whooshing sounds at the connections. If there are audible leaks, shut off the engine and retighten the corresponding clamp. After confirming no leaks, take the car for a short test drive to recheck alignment under movement. Final-torque all fasteners after the system has heat-cycled once.

Professional installers will have access to a lift and will typically be faster, but DIY is entirely realistic in an afternoon. Allow 2–3 hours for first-timers.

Sound Comparison: Touring Edition vs. Stock vs. Competition

The AWE Touring Edition is not the loudest cat-back on the market, and that is intentional. Here is how it stacks up against other popular options for the RS5 2.9TT:

Stock Exhaust (OEM)

Quiet, refined, and mostly silent at idle. At full throttle it produces a muted note that is often described as “polite.” Virtually zero drone, but no character. Weight: ~35–40 lbs.

AWE Touring Edition (Resonated)

Deep idle, moderate interior presence. No drone at highway speeds. Can be heard clearly from outside but does not attract unwanted attention in neighborhoods. Weight: ~27 lbs (saves 8–13 lbs).

AWE Track Edition (Non-Resonated, Open Track)

Significantly louder than the Touring, with more pronounced drone inside the cabin. Best for weekend drivers or track-focused builds. Not recommended for long highway commutes.

Milltek Non-Resonated

Similar volume to AWE Track but with a slightly higher pitch. Some owners report drone at 2,000–2,500 rpm under load. Build quality is excellent but alignment can be finicky.

Akrapovič Evolution Line (Titanium)

Premium price tag ($4,500+) but saves over 20 lbs vs stock. Sound is metallic and refined, less bassy than AWE. Best for weight-conscious owners with large budgets.

For the majority of RS5 owners who want a noticeable sound upgrade without turning the interior into a resonance chamber, the AWE Touring Edition remains the goldilocks choice.

Long-Term Ownership: Durability and Warranty

AWE backs its exhaust systems with a limited lifetime warranty for the original purchaser, covering defects in materials and workmanship. The stainless steel construction is resistant to corrosion, but like any aftermarket exhaust, regular cleaning of the tips and inspection of the hangers is recommended. In regions with heavy road salt, owners should periodically wash the underside to prevent surface rust on the welds (unlikely but possible if not maintained).

One potential long-term consideration: the non-resonated mid-pipes may produce a faint tinny resonance after 15,000+ miles, but this is subjective and varies by vehicle. The resonated version stays consistent over time. AWE also offers a lifetime warranty on the muffler body and connections, which is a strong indicator of confidence in the product.

Performance Data and Owner Reviews

While dyno figures vary, the most consistent results from owner logs on Audi forums and independent shops show:

  • Peak gain +10 hp at 5,800 RPM (stock tune)
  • +12 lb-ft at 3,200 RPM (mid-range improvement)
  • 0-60 mph times unaffected on stock tune; with ECU flash, may see 0.1–0.2 sec improvement.
  • Weight reduction: 12–18 lbs, depending on tip size.

Owners on forums like AudiWorld and Reddit’s r/Audi consistently praise the fitment, lack of drone, and the fact that the Touring Edition remains daily-driver-friendly. A minority of reviewers who wanted a raw race sound have upgraded to the Track Edition later, but most are satisfied with the Touring.

Is the Upgrade Worth $2,000?

Given the cost of a new OEM replacement exhaust for the RS5 (roughly $1,200 from Audi dealer), spending $2,000 on a premium aftermarket cat-back is a significant but justifiable investment for those who value driving emotion. The car feels faster even if the numbers are modest, and the sound transforms the identity of the RS5 from a quiet grand tourer to an engaging sports coupe. Resale value can also be a factor: a tasteful exhaust system often broadens the buyer pool, and many enthusiasts will pay a premium for a clean example with a non-destructive upgrade.

If you do most of your own maintenance and are comfortable with tools, the $300–500 saved on labor makes the project even more worthwhile. For those who strictly want maximum power per dollar, a stage 1 ECU tune (often $500–700) will yield bigger gains, but combining a tune with the AWE exhaust creates a truly addictive driving experience.

Where to Buy and Installation Resources

Always buy from an authorized AWE Tuning dealer to ensure warranty and avoid counterfeit products. Reputable online vendors include:

Final Verdict

The AWE Touring Edition Exhaust for the Audi RS5 2.9TT delivers exactly what it promises: a refined, aggressive sound, solid build quality, and a noticeable improvement in throttle response. For a total outlay of around $2,000 (including professional installation), you gain a daily-drivable exhaust that turns heads without rattling your fillings. The drone-free cruising makes it suitable for long road trips, and the ability to upgrade to non-resonated mid-pipes later offers a clear path to more volume if desired. If you are on the fence, try to find a local RS5 meet or watch high-quality audio clips online – but be warned, once you hear it in person, the credit card tends to come out fast.
