Titanium construction provides excellent heat resistance and a more responsive driving feel. With the valves closed, the exhaust maintains a refined tone suitable for everyday use, while opening them transforms the sound into a more aggressive, performance-focused note. APEX provides this system as a direct-fit upgrade with full valve functionality and factory-compatible integration.\u003c\/p\u003e","brand":"Apex Auto","offers":[{"title":"Purple","offer_id":47536828547326,"sku":null,"price":3999.0,"currency_code":"USD","in_stock":true},{"title":"Blue","offer_id":47536828580094,"sku":null,"price":3999.0,"currency_code":"USD","in_stock":true},{"title":"Gold","offer_id":47536828612862,"sku":null,"price":3999.0,"currency_code":"USD","in_stock":true},{"title":"Purple Gold","offer_id":47536828645630,"sku":null,"price":3999.0,"currency_code":"USD","in_stock":true},{"title":"Titanium Raw","offer_id":47536828678398,"sku":null,"price":3999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/8844\/4926\/files\/1_0b0bf48d-aeab-45c9-8051-653cb0b432e2.png?v=1763404165","url":"https:\/\/www.apexinc.co\/products\/audi-rs3-8y-2-5t-2021-high-performance-titanium-exhaust-system-copy","provider":"Apex Auto","version":"1.0","type":"link"}
