The MagnaFlow 106-0133 is a BRExhaust direct-fit replacement cat-back system for the 2.5L Subaru Forester and Impreza, sold as a bolt-on swap rather than a custom fabrication job. These kits feature durable, corrosion-resistant aluminized steel construction backed by a limited 2-year construction warranty. Compared with a worn stock system or a universal pipe that needs cutting and welding, this kit arrives with its hangers, gaskets, and clamps in one box, which makes it a practical choice for a street or track-day car where time under the lift matters.
Fitment is the first thing to verify. The manufacturer's product page says the kit is designed to fit the 2009-2013 Subaru Forester 2.5L & 2008-2011 Subaru Impreza 2.5i 2.5L. However, a fitment display on the manufacturer's collection page lists this kit as "Does Not Fit," so confirm your vehicle's EFN before ordering. Owners on user forums should be consulted for real-world fit reports, and the installer should check hanger alignment before tightening anything. No bending or welding is required for installation. The kit includes clamps, hangers, and gaskets, with two exhaust tips, and searches for "2.5L Forester cat-back direct fit," "Impreza 2.5i replacement exhaust," and "106-0133 EFN" will find the right application.
The manufacturer says to check your EFN, which is listed on the emission tag under the hood, on the suspension tower, or on the radiator shroud. Compare that number against the manufacturer's application list before ordering.
The manufacturer states the U-bolt clamps interchange with OE parts 44200SC000, 44200SC030, 44200SC031, 44300SC000, 44300SC020, 44300SC030, 44300SC120, 44300SC130, 44300SC140, 44300SC142, 44300SC160, 44300SC170, 44300SC200, and 44300SC210. Verify your original part number against this list.
The manufacturer provides a limited 2-year construction warranty on the kit.
The manufacturer describes an easy-to-install direct-fit design with no bending or welding needed, so this is a bolt-up job for a home mechanic comfortable working under the car. The box contains a spring bolt kit, a donut gasket, two-bolt gaskets, and nut and bolt kits to reconnect the system. Check the fit of the hangers and the alignment of each pipe before tightening the U-bolt clamps, and confirm your EFN first to avoid returning the kit. I did not locate the manufacturer's install sheet or owner install reports during research, so check the sheet for torque values and assembly sequence before starting.
