The MagnaFlow Touring Series cat-back system (part 15352) replaces the exhaust from the catalytic converter rearward on the 2.0L turbocharged 8V Audi A3 Quattro. The manufacturer describes mandrel-bent 2.5-inch piping, 409 stainless steel construction, and 3.5-inch polished double-wall tips in a dual split rear exit. Compared with the stock system, the draw is a deeper, more resonant exhaust note, along with the manufacturer's claim of increased horsepower and torque. The kit was developed with 3D scanning to match factory mounting points, which helps avoid the fit problems common with universal pipe kits that need modification.
Search terms this kit matches include 8V A3 2.0T Quattro cat-back exhaust, Touring Series stainless cat-back, and dual split rear exit A3 Quattro. The manufacturer lists the system for the 2015 to 2020 A3 Quattro 2.0L, so confirm your model year and trim before ordering. Owners on user forums note that the system has no resonator, and that in-cabin drone can shift during the first several hundred to roughly a thousand miles while the muffler packing breaks in. One owner added butyl sound deadening to the rear shelf. Installation is a bolt-on job, but the manufacturer recommends basic automotive knowledge and suggests professional installation when possible.
The manufacturer lists the catalytic converter as not included and states that no gasket or seal comes with the system. You will need to keep your factory catalytic converter, and the manufacturer says the kit includes the clamps and hardware needed for installation.
The manufacturer's compatibility list includes 2019 and 2020 A3 Quattro 2.0L models, and its product listing covers 2015 to 2020. The manufacturer's own fitment tool showed a conflicting "Does Not Fit" notice, so confirm fitment with the manufacturer before ordering.
Owners on user forums report that the system has no resonator and that the exterior tone is subtle unless the engine is under load. Some owners report that cabin drone changes as the muffler breaks in over the first few thousand miles, so results vary.
The manufacturer describes this as a bolt-on installation that requires basic automotive knowledge, and recommends professional installation when possible. Owners on user forums mention that clearance under the heat shield just behind the catalytic converter is tight, so check the fit of the front pipe before fully tightening the clamps. Because no gasket is included, check the inlet connection carefully for leaks after installation.
