Available in both premium stainless steel and lightweight titanium versions, this axle-back system transforms the car with a louder, deeper, and far more aggressive exhaust note while improving overall exhaust flow and turbo response. The straight-through Race Spec design reduces restriction to help the EJ-series engine breathe more freely, bringing out sharper throttle response, louder turbo spool, and that unmistakable Subaru rumble enthusiasts love. Whether you’re carving through mountain roads, hitting weekend meets, or doing the occasional tunnel pull “for research purposes,” the sound delivers the perfect balance of raw aggression and turbocharged personality.\u003c\/p\u003e\n\u003cp data-start=\"2021\" data-end=\"2795\" data-is-last-node=\"\" data-is-only-node=\"\"\u003eBuilt with mandrel-bent piping and precision TIG-welded construction, the Rev9 FlowMAXX exhaust system is engineered for durability, heat resistance, and long-term street or performance use. The stainless steel version delivers excellent durability and a deep performance tone, while the titanium setup adds weight savings and a sharper, more exotic race-inspired sound profile. Rev9 has become a go-to brand for enthusiasts looking for aggressive styling, proven fitment, and real sound improvement without spending premium boutique exhaust money. If your WRX STI feels too restricted from the factory and you want the car to sound more alive every time boost kicks in, the Rev9 FlowMAXX Race Spec Exhaust is the upgrade that finally gives the car the attitude it deserves.\u003c\/p\u003e","brand":"Rev9","offers":[{"title":"Standard \/ Stainless Steel","offer_id":42368527106128,"sku":"CB-1120","price":450.0,"currency_code":"USD","in_stock":true},{"title":"Track \/ Stainless Steel","offer_id":42368527138896,"sku":"CB-1120A","price":350.0,"currency_code":"USD","in_stock":true},{"title":"Track \/ Titanium","offer_id":42368527171664,"sku":"CB-1120A-TI","price":770.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0058\/0252\/4785\/files\/cb-1120a-ti_1.jpg?v=1778854474","url":"https:\/\/shop.redline360.com\/products\/rev9-exhaust-for-subaru-impreza-wrx-sti-sedan-gj-2011-2014-3-flowmaxx-axleback-titanium-stainless-steel-race-spec","provider":"Redline360","version":"1.0","type":"link"}
