On this twin-turbo V8 it is the most strangled point in the circuit: replacing it is the only way to go after horsepower, and only with a remap. Without it you gain sound and lose a little weight, nothing else. The 200-cell sport catalytic converter retains exhaust after-treatment; the 100-cell version and the catalyst-free variant do not. No component type approval exists for these parts: check the regulations in your country before fitting.\u003c\/p\u003e\u003cdiv data-rog-guide=\"v2\" style=\"margin-top:28px;padding-top:20px;border-top:1px solid rgba(0,0,0,.11);\"\u003e\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:10px;\"\u003e\n\u003ca class=\"rogx-guide__btn rogx-guide__btn--fort\" href=\"\/en-lu\/blogs\/guides\/guide-echappement-bmw-m850i-g14-g15-g16-4-4tt-20202023\" style=\"display:inline-flex;align-items:center;gap:8px;padding:12px 20px;border-radius:980px;text-decoration:none;font-size:15px;font-weight:500;font-family:-apple-system,BlinkMacSystemFont,'SF Pro Text','Helvetica Neue',Helvetica,Arial,sans-serif;line-height:1.2;white-space:nowrap;background:#1D1D1F;color:#fff\"\u003e\u003cspan\u003eRead the full guide\u003c\/span\u003e\u003csvg viewbox=\"0 0 24 24\" width=\"15\" height=\"15\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2.2\" stroke-linecap=\"round\" stroke-linejoin=\"round\" aria-hidden=\"true\" style=\"flex:none\"\u003e\u003cpath d=\"M5 12h13M12 5l7 7-7 7\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/a\u003e\u003ca class=\"rogx-guide__btn\" href=\"\/en-lu\/collections\/echappement-bmw\" style=\"display:inline-flex;align-items:center;gap:8px;padding:12px 20px;border-radius:980px;text-decoration:none;font-size:15px;font-weight:500;font-family:-apple-system,BlinkMacSystemFont,'SF Pro Text','Helvetica Neue',Helvetica,Arial,sans-serif;line-height:1.2;white-space:nowrap;background:#F5F5F7;color:#1D1D1F\"\u003e\u003cspan\u003eAll BMW systems\u003c\/span\u003e\u003c\/a\u003e\u003ca class=\"rogx-guide__btn\" href=\"\/en-lu\/pages\/echappements-par-marque\" style=\"display:inline-flex;align-items:center;gap:8px;padding:12px 20px;border-radius:980px;text-decoration:none;font-size:15px;font-weight:500;font-family:-apple-system,BlinkMacSystemFont,'SF Pro Text','Helvetica Neue',Helvetica,Arial,sans-serif;line-height:1.2;white-space:nowrap;background:#F5F5F7;color:#1D1D1F\"\u003e\u003cspan\u003eAll 22 brands\u003c\/span\u003e\u003c\/a\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003c!-- rog-maillage --\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eOther versions and closely related engines\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/en-lu\/products\/echappement-bmw-840i-b58-g16-3-0t\"\u003e840i B58 G16 3.0T\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-lu\/products\/echappement-bmw-m5-f10-4-4tt\"\u003eM5 F10 4.4TT\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-lu\/products\/echappement-bmw-m550i-n63-g30-4-4tt\"\u003eM550i N63 G30 4.4TT\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en-lu\/products\/echappement-bmw-m6-f06-f12-f13-4-4tt\"\u003eM6 F06 \/ F12 \/ F13 4.4TT\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee all the \u003ca href=\"\/en-lu\/collections\/echappement-bmw\"\u003eBMW valved exhaust systems\u003c\/a\u003e.\u003c\/p\u003e\u003c!-- \/rog-maillage --\u003e","brand":"ROG Motorsport","offers":[{"title":"Stainless steel \/ No manifold","offer_id":60851649839438,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-INOX-SANS","price":3390.0,"currency_code":"EUR","in_stock":true},{"title":"Stainless steel \/ Catalyst-free manifold","offer_id":60851649872206,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-INOX-DECAT","price":4270.0,"currency_code":"EUR","in_stock":true},{"title":"Stainless steel \/ 100-cell sport manifold","offer_id":60851649904974,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-INOX-SP100","price":4680.0,"currency_code":"EUR","in_stock":true},{"title":"Stainless steel \/ 200-cell sport manifold","offer_id":60851649937742,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-INOX-SP200","price":4680.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ No manifold","offer_id":60851649970510,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-TI-SANS","price":4140.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ Catalyst-free manifold","offer_id":60851650003278,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-TI-DECAT","price":5020.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ 100-cell sport manifold","offer_id":60851650036046,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-TI-SP100","price":5430.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ 200-cell sport manifold","offer_id":60851650068814,"sku":"ROG-192-BMW-M850I-G14-G15-G16-4-4TT-TI-SP200","price":5430.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/5079\/3806\/files\/bmw-m850i-g14-g15-g16-4-4tt-ligne-echappement.png?v=1789655009","url":"https:\/\/rogmotorsport.com\/en-lu\/products\/exhaust-bmw-m850i-g14-g15-g16-4-4tt","provider":"ROG","version":"1.0","type":"link"}
