The MagnaFlow BRExhaust 106-0094 is a direct-fit replacement exhaust system for the 2006-2008 Subaru Forester 2.5L, engineered to take the place of the factory system and to replace OE part number 44200SA040. It is made from aluminized steel and uses precision mandrel-bent piping rather than the crush-bent tubing common in budget replacements, which the manufacturer says improves exhaust flow. For a Forester owner searching for a 2006 2007 2008 Subaru Forester 2.5L mandrel bent exhaust or a bolt-on OEM-replacement cat-back, that tubing difference is the main reason to spend more than a generic muffler-and-pipe kit costs.
Compared with stock, the kit is a like-for-like replacement built around the factory mounting points, and the manufacturer states that it leaves all emissions equipment intact, so the vehicle stays emissions-compliant. It also carries a two-year, unlimited-mileage warranty, which is a meaningful safeguard against the premature rust and failures that cheaper systems often show. Buyers looking for a replacement exhaust for a Subaru Forester 2.5L with a long-term corrosion-resistance argument will find that the warranty and aluminized construction make the price easier to justify.
The manufacturer states that the kit leaves all emissions equipment in place, which it says keeps the vehicle emissions-compliant. Confirm any state-specific requirements, such as California CARB rules, with the manufacturer before purchase.
No. The manufacturer states that no bending or welding is required, and the multi-piece, adjustable design is meant to route around axles, crossbars, and brackets.
Per the manufacturer, the kit includes the gaskets, spring bolt kit, clamps, and hardware needed for installation, packaged together with installation instructions.
The manufacturer lists a two-year warranty with unlimited mileage.
The manufacturer describes this as a bolt-on, multi-piece system that does not require cutting or welding, so it is a practical driveway project for a home mechanic with basic hand tools and a jack or lift. Because the pieces are designed to be fitted around obstacles such as axles and crossbars, you can position each section before fully tightening the clamps. Owners on user forums recommend soaking the rusted exhaust fasteners with penetrating oil, ideally overnight, and having a impact wrench on hand for stubborn hardware. Forum posters also note that the upstream and downstream oxygen sensors may require special sensor sockets to remove, so check that you have the right tool before starting. Owners on forums often use a high-temperature silicone gasket maker on joints to help seal them, but confirm the recommended sealing approach with the manufacturer's instructions that come in the box.
