{"product_id":"mercedes-amg-cls63-w218-valved-exhaust-system","title":"Mercedes-AMG CLS63 W218 Valved Exhaust System","description":"\u003cp\u003eThe NRP Valved Exhaust System for the Mercedes-AMG CLS63 W218 replaces the factory exhaust from the downpipes back with a full valved catback. The 5.5L M157 twin-turbo V8 has one of the best voices AMG ever built, and the stock exhaust keeps most of it inside the car. With the valves open you get the full V8 rumble with hard crackles on overrun; closed, the CLS goes back to being a quiet cruiser. Direct bolt-on using the factory mounting points, and 100% reversible.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFull valved catback — replaces the factory system from the downpipes back\u003c\/li\u003e\n\u003cli\u003eElectronic exhaust valves — quiet with the valves closed, full volume open\u003c\/li\u003e\n\u003cli\u003eMandrel-bent, TIG-welded construction for maximum flow\u003c\/li\u003e\n\u003cli\u003eWorks with the OEM downpipes or any aftermarket downpipes built for them\u003c\/li\u003e\n\u003cli\u003eNo check engine light — fully post-cat\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on, no cutting or welding; 100% reversible\u003c\/li\u003e\n\u003cli\u003eNRP Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eFitment:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2012–2018 Mercedes-AMG CLS63 \/ CLS63 S (W218, including Shooting Brake)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eProfessional installation recommended.\u003c\/p\u003e","brand":"NightRunners Performance","offers":[{"title":"Default Title","offer_id":52680573550963,"sku":"","price":2275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0929\/8405\/0035\/files\/Photoroom_20250619_191206.jpg?v=1750379701","url":"https:\/\/www.nightrunnersperformance.com\/products\/mercedes-amg-cls63-w218-valved-exhaust-system","provider":"NightRunners Performance","version":"1.0","type":"link"}
