{"product_id":"n20-downpipe-w-bracket-mad-bmw-228-328-428","title":"N20 Downpipe Catless Downpipe","description":"\u003cp\u003eUnlock the full potential of your N20 with the Catless Downpipe. Designed for F-chassis BMW models running the N20 2.0L twin-scroll turbo four, this catless downpipe eliminates the restrictive factory catalytic converter and opens up real power, faster spool, and the proper turbo-four soundtrack the OEM exhaust completely buries. The foundational mod for any Stage 2 N20 build — F30 328i, F32 428i, F22 228i, F10 528i, and X-Series 28i.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cp\u003e* Catless High-Flow Design: Removes the restrictive OEM catalytic converter. Faster turbo spool, reduced backpressure, and noticeable top-end gains. Typical Stage 2 builds see 20-35 WHP and 25-35 WTQ improvements when paired with a proper tune.\u003c\/p\u003e\n\u003cp\u003e* N20 Sound Transformation: Unmuffles the N20 turbo four. Deeper exhaust note, audible turbo spool, blow-off chatter, and the pronounced overrun pops that BMW engineered out of the factory exhaust.\u003c\/p\u003e\n\u003cp\u003e* F-Chassis Specific Engineering: Built specifically for F-series N20 chassis layouts and exhaust routing. NOT cross-compatible with E-chassis N20 cars (E84 X1 28i, E89 Z4 28i) — exhaust geometry, flange placement, and length differ.\u003c\/p\u003e\n\u003cp\u003e* 3\" T304 Stainless Construction: Mandrel-bent piping with CNC-machined OEM flanges, hand TIG-welded throughout. Corrosion-proof, heat-tolerant, built to handle high-boost builds and sustained track use.\u003c\/p\u003e\n\u003cp\u003e* Direct OEM Flange Fitment: Bolts straight to the OEM turbo outlet and stock mid-pipe section. No cutting, no welding, no custom fabrication required. Compatible with both RWD and xDrive variants.\u003c\/p\u003e\n\u003cp\u003e* Stage 2 Build Foundation: Required for serious tune levels. Pairs perfectly with MHD, JB4, Bootmod3, FMIC upgrades, and intake systems. The first step in unlocking what the N20 is actually capable of.\u003c\/p\u003e\n\u003cp\u003eIMPORTANT COMPLIANCE NOTE: Catless downpipes are designed for OFF-ROAD \/ TRACK USE ONLY. Removes the catalytic converter required for road registration in Australia and most international markets. NOT legal for road-registered vehicles. Will trigger check engine lights and emissions codes without proper tuning.\u003c\/p\u003e\n\u003cp\u003eTUNE REQUIRED: To unlock full power potential and clear fault codes, a custom or off-the-shelf tune (MHD, JB4, Bootmod3, etc.) is required after fitment.\u003c\/p\u003e","brand":"NuroTech™","offers":[{"title":"Default Title","offer_id":51318947086651,"sku":"N20-CDP","price":399.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/8273\/4139\/files\/Untitled_1080x1080px_39.png?v=1780833401","url":"https:\/\/nuroperformance.com\/products\/n20-downpipe-w-bracket-mad-bmw-228-328-428","provider":"Nuro Performance","version":"1.0","type":"link"}
