Boost Logic Downpipe for 8V / 8Y Audi RS3
Boost Logic’s Downpipe for 8V / 8Y Audi RS3 carries the 2.5-liter five-cylinder’s exhaust through a large 4.0-inch outlet that splits into dual 2.5-inch pipes, a layout Boost Logic sized to cut back pressure compared to the factory system. The flanges are laser cut and the V-band connections precision machined, so the joints line up and seal without leaks. Boost Logic lists it for both RS3 generations, the 2017-2020 8V and the 2022 and later 8Y. The part is simple; the install is not, because the front driveshaft has to come out, so it makes most sense for an owner already planning deeper work on the car.
Features
- Large 4.0-inch outlet that splits into dual 2.5-inch pipes
- Laser-cut flanges for accurate alignment at each joint
- Precision-machined V-band connections built for a leak-free seal
- Flow-focused layout that reduces back pressure compared to the factory system
Applications
- Audi RS3: 8V | 2017-2020 | 2.5L TFSI I5
- Audi RS3: 8Y | 2022-present | 2.5L TFSI I5
Notes
- Installation requires removal of the front driveshaft, and Boost Logic highly recommends using a driveshaft removal tool
- Boost Logic lists the Downpipe for 8V / 8Y RS3 for both RS3 generations; the 8S TT RS uses its own part, the Boost Logic Downpipe for 8S Audi TT RS (BL 11010601)
- Boost Logic publishes no horsepower or torque figure for this downpipe, so no gain is quoted here
- For the exhaust behind it, Boost Logic builds the Boost Logic Formula Series Titanium Exhaust for 8V Audi RS3 (BL 11010109) and the Boost Logic Titanium Exhaust for 8Y Audi RS3 (11010110)
Frequently Asked Questions
- Does the Boost Logic Downpipe for 8V / 8Y RS3 fit both RS3 generations? Yes. Boost Logic states that the Downpipe for 8V / 8Y RS3 fits both the 8V chassis, sold from 2017 to 2020, and the 8Y chassis sold from 2022 on, each with the 2.5 liter TFSI five-cylinder engine. The 8S TT RS shares that engine, but Boost Logic lists a separate downpipe part number for it, so TT RS owners should order that listing.
- What is involved in installing this downpipe? The front driveshaft has to be removed to fit the downpipe, and Boost Logic highly recommends using a driveshaft removal tool for that step. Because of the driveshaft work this is a job for a lift and an experienced installer, so budget shop time accordingly if you are not planning to do the installation yourself.
- What size is the downpipe? The downpipe uses a large 4.0 inch outlet that splits into dual 2.5 inch pipes. Boost Logic sized it for exhaust flow and lower back pressure compared to the factory system. The connections are precision machined V-band joints with laser cut flanges, which Boost Logic uses so the part fits accurately and seals without leaks.
- How much power does the downpipe add? Boost Logic says the downpipe improves exhaust flow and adds horsepower and torque, but it does not publish a dyno figure or a test configuration for the RS3. Any gain depends on the tune and the rest of the setup, so plan calibration changes with your tuner before installation rather than expecting a set number from the part alone.
- Does the downpipe come with gaskets and hardware? Boost Logic does not publish a parts list for this downpipe, so gaskets, clamps and fasteners should not be assumed to be in the box. Contact Bulletproof Automotive before ordering to confirm exactly what ships with it, and have new gaskets on hand for the installation in case the factory pieces cannot be reused.
