Kooks 2020 Toyota Supra 3.5in x 3in SS Resonator Delete Mid-Section

The Kooks 3.5-inch to 3-inch stainless steel resonator delete mid-section replaces the restrictive factory secondary resonator on 2020–2025 Toyota GR Supra A90 models with the 3.0L B58 turbo engine, providing a straight-through path that reduces backpressure for dyno-proven gains of 12–18 rear-wheel horsepower and 15–25 lb-ft of torque while unleashing a deeper, more aggressive turbocharged soundtrack without interior drone. Handcrafted from T304 aircraft-quality stainless steel with mandrel bends and full TIG welds, this direct bolt-on section uses OEM-style flanges and hangers for plug-and-play installation with no cutting or welding required. The stepped design maintains factory ground clearance while flowing significantly better than the stock 2.5-inch resonator for faster turbo spool and improved throttle response. For Supra A90 owners seeking maximum flow and race-inspired sound while retaining factory cat-back mufflers, the Kooks 44114300 resonator delete is the complete mid-section upgrade trusted by B58 tuners worldwide.
