It offers the flexibility to run OEM valve integration, pair with additional exhaust modifications, or install as a standalone upgrade — all without compromising fit, finish, or tone. TIG-welded from T304 stainless steel and designed around factory mounting points and cut locations, the system delivers an OEM+ installation and appearance, with 3.5\" tips that fill the rear bumper cleanly.\u003c\/p\u003e\n\u003cp\u003eWith the valves closed, all exhaust gases route through a precision-engineered quad-chambered muffler for stock-level volume — ideal for early morning starts, stealthy commuting, and drone-free cruising. With the valves open, the muffler is bypassed entirely, freeing exhaust flow for a deeper, more engaging tone without unwanted cabin drone. The electronic valves operate through the car's factory BMW drive modes for instant control, and the system is 100% reversible back to stock at any time.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMaterial: Premium T304 stainless steel, fully mandrel-bent, precision TIG-welded\u003c\/li\u003e\n\u003cli\u003eOutlet: Customizable 3.5\" tips for an OEM+ look, five finish options\u003c\/li\u003e\n\u003cli\u003eValves: OEM electronic valves with rapid open\/close function, integrated with factory drive modes\u003c\/li\u003e\n\u003cli\u003eFitment: Uses factory mounting points and cut locations for OEM+ installation\u003c\/li\u003e\n\u003cli\u003eExtension harness included for plug-and-play operation\u003c\/li\u003e\n\u003cli\u003e100% reversible — return to stock at any time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eComplete kit as supplied by Valvetronic Designs; see the installation instructions for the full bill of materials.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNone.\u003c\/strong\u003e Valvetronic Designs ships this system as a complete bolt-on kit; no additional hardware is required for a basic installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNo manufacturer install video is currently published for this specific system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eVendor also lists the 330e plug-in hybrid and 2025+ model-year cars as compatible \"with modifications\" — the modification isn't specified by Valvetronic Designs; confirm with Speed Logic before ordering for a 330e or a 2025+ car.\u003c\/li\u003e\n\u003cli\u003ePriced at Valvetronic Designs' direct list price.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePART NUMBER\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW.G20.330i.AXL.BR.BRSH\u003c\/strong\u003e — Brushed Steel tips — $1,259.99\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW.G20.330i.AXL.BR.BRT\u003c\/strong\u003e — Burnt tips — $1,259.99\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW.G20.330i.AXL.BR.BLK\u003c\/strong\u003e — Black tips — $1,259.99\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW.G20.330i.AXL.BR.FC\u003c\/strong\u003e — Forged Carbon tips — $1,259.99\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBMW.G20.330i.AXL.BR.RC\u003c\/strong\u003e — 1x1 Carbon tips — $1,259.99\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eVEHICLE APPLICATIONS\u003c\/h2\u003e\n\u003ctable class=\"va-table\"\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e330i\u003c\/td\u003e\n\u003ctd\u003eG20\u003c\/td\u003e\n\u003ctd\u003eB48 2.0L Turbo I4\u003c\/td\u003e\n\u003ctd\u003e2019–2024\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e430i\u003c\/td\u003e\n\u003ctd\u003eG22\u003c\/td\u003e\n\u003ctd\u003eB48 2.0L Turbo I4\u003c\/td\u003e\n\u003ctd\u003e2019–2024\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBMW\u003c\/td\u003e\n\u003ctd\u003e430i Convertible\u003c\/td\u003e\n\u003ctd\u003eG23\u003c\/td\u003e\n\u003ctd\u003eB48 2.0L Turbo I4\u003c\/td\u003e\n\u003ctd\u003e2019–2024\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e","brand":"Valvetronic Designs","offers":[{"title":"Brushed Steel","offer_id":52607329468696,"sku":"BMW.G20.330i.AXL.BR.BRSH","price":1259.99,"currency_code":"USD","in_stock":false},{"title":"Burnt","offer_id":52607329501464,"sku":"BMW.G20.330i.AXL.BR.BRT","price":1259.99,"currency_code":"USD","in_stock":false},{"title":"Black","offer_id":52607329534232,"sku":"BMW.G20.330i.AXL.BR.BLK","price":1259.99,"currency_code":"USD","in_stock":false},{"title":"Forged Carbon","offer_id":52607329567000,"sku":"BMW.G20.330i.AXL.BR.FC","price":1259.99,"currency_code":"USD","in_stock":false},{"title":"1x1 Carbon","offer_id":52607329599768,"sku":"BMW.G20.330i.AXL.BR.RC","price":1259.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2307\/8117\/files\/A7400006.jpg?v=1788388980","url":"https:\/\/speedlogicauto.com\/products\/valvetronic-designs-valved-axle-back-exhaust-bmw-330i-430i-g20-g22-g23","provider":"SPEED LOGIC","version":"1.0","type":"link"}
