Invidia HS04SFRG2S G200 Cat-Back Exhaust for 2004-2008 Subaru Forester XT 2.5L

Vehicle Fitment

• 2004-2008 Subaru Forester XT (SG chassis | EJ255 2.5L DOHC Turbo | All trims: XT, XT Premium, XT Limited, XT Sports, XT LL Bean)

Fitment Notes

• Compatible with all trim levels of the second-generation Subaru Forester XT equipped with the EJ255 2.5L turbocharged horizontally opposed four-cylinder engine. Does not fit non-turbo Forester X or XS models equipped with the 2.5L SOHC EJ253 engine - those models use a different exhaust configuration.
• Does not fit the 2009+ third-generation Forester XT (SH chassis), which uses a different exhaust outlet configuration.
• If retaining the factory downpipe, a downpipe-to-cat-back adapter may be required for proper fitment. Aftermarket downpipes designed for the SG Forester XT may connect directly without an adapter. Verify your downpipe configuration before ordering.
• Exhaust hangers are welded at OEM locations for a direct bolt-on installation at the stock hang points.
• 50-state legal.

Features

• G200 series cat-back exhaust engineered specifically for the 2004-2008 Forester XT - 3D scanned from the underside of the vehicle during development to ensure 100% accurate fitment with no trimming, cutting, or modification required
• 76mm (3") SUS304 stainless steel mandrel-bent piping replaces the factory press-bent smaller-diameter exhaust, reducing back pressure and improving exhaust gas scavenging across the EJ255's RPM range
• 110mm (4.33") rolled polished stainless steel tip provides a clean, premium rear bumper appearance that complements the Forester XT's functional styling
• Resonated cannon-style muffler is specifically tuned to deliver the G200's characteristic deep, throaty sound with a minimal rasp - a controlled, authoritative exhaust note that enhances the EJ255's flat-four turbo character without excessive drone on the highway
• Single rear exit design integrates cleanly with the SG Forester XT's bumper cutout for a factory-coherent appearance from the rear
• CNC machined flanges ensure precise, leak-free connections throughout the system - no exhaust leaks at flange joints
• New gaskets and all necessary hardware included for a complete installation
• Robot TIG welded construction provides consistent, high-strength welds throughout the system
• 304 stainless steel construction provides long-term corrosion resistance, thermal stability under repeated heat cycling, and a self-maintaining polished appearance
• Covered by Invidia's 1-year manufacturer warranty against defects in material and workmanship

Product Description

The Invidia HS04SFRG2S is a G200 series cat-back exhaust system designed specifically for the 2004-2008 Subaru Forester XT equipped with the EJ255 2.5L turbocharged boxer four-cylinder engine. It replaces the factory exhaust from the catalytic converter back with 76mm (3") mandrel-bent SUS304 stainless steel piping, a resonated cannon-style muffler, and a 110mm rolled polished stainless steel tip - delivering measurably reduced exhaust back pressure, improved mid-to-top-end power, and the G200's signature deep throaty exhaust note without the rasp that plagues many budget cat-back systems.

Invidia develops each G200 system using a 3D scan of the underside of the specific vehicle to ensure fitment accuracy - every bend, hanger location, and flange position is engineered to match the exact geometry of the SG Forester XT. The result is a system where the exhaust hangers bolt directly to the OEM mounting points with no cutting or modification required. Owners retaining the factory downpipe should note that a downpipe-to-cat-back adapter may be needed for proper fitment; aftermarket downpipes designed for the SG XT typically connect directly. The G200's resonated cannon muffler is internally tuned to amplify the EJ255's naturally aggressive flat-four exhaust character - particularly the distinctive turbo flutter and flat-four rumble under boost - while keeping highway drone and rasp at bay for a system that's equally enjoyable on daily commutes and spirited backroads.

SUS304 stainless steel construction ensures long-term corrosion resistance across the Pacific Northwest and northeast US climates where Foresters commonly live. Robot TIG welding and CNC machined flanges at every joint ensure structural integrity and leak-free performance. The HS04SFRG2S is 50-state legal and covered by Invidia's 1-year manufacturer warranty against defects in material and workmanship.
