{"product_id":"axleback-exhaust-w-5-inch-muffler-helmholtz-resonator","title":"Axleback Exhaust w\/ 5-Inch Muffler \u0026 Helmholtz Resonator","description":"Designed for the 2024+ Subaru Impreza RS with the FB25 engine, this axleback exhaust features a dual-chamber configuration that pairs a 5-inch zero-restriction muffler with a frequency-tuned Helmholtz resonator. This engineering approach effectively cancels out drone frequencies during cruising and high-load, low-RPM driving to ensure a refined cabin experience.\n\nThe system is constructed from CNC mandrel-bent 2.25-inch T304 stainless steel tubing, featuring polished 3-inch staggered double-wall quad exhaust tips that integrate into factory bumper cutouts. Every unit is hand TIG-welded in Woodland, Washington, and includes a full hardware kit and gaskets for a precise, bolt-on installation to OEM or OEM-fitment midpipes.\n\nPlease note that this product is not compatible with older Impreza models or 2.0L engines; a dedicated 2.0L version is available separately. Ensure your vehicle configuration matches the specified engine type before purchase.","brand":"Nameless Performance","offers":[{"title":"Default Title","offer_id":52663084712248,"sku":"SUAB24IMW25-QUAD","price":961.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687514633.jpg?v=1784323651","url":"https:\/\/store.motormia.co\/products\/axleback-exhaust-w-5-inch-muffler-helmholtz-resonator","provider":"MOTORMIA","version":"1.0","type":"link"}
