On a naturally aspirated engine its design is not cosmetic: lengths and geometry decide cylinder filling at high revs. Paired with a remap it returns in the order of 3 to 8 %, a real but modest gain. Badly designed, it costs you torque down low. 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\/blogs\/guides\/maserati-granturismo-v8-2007-2019-exhaust-guide\" 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\/collections\/exhaust-maserati\" 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 Maserati systems\u003c\/span\u003e\u003c\/a\u003e\u003ca class=\"rogx-guide__btn\" href=\"\/en\/pages\/valved-exhausts-by-brand\" 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 28 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\/products\/exhaust-maserati-granturismo-v8-4-2\"\u003eGranTurismo V8 4.2\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en\/products\/exhaust-maserati-granturismo-v6\"\u003eGranTurismo \/ GranCabrio V6\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee all the \u003ca href=\"\/en\/collections\/exhaust-maserati\"\u003eMaserati valved exhaust systems\u003c\/a\u003e.\u003c\/p\u003e\u003c!-- \/rog-maillage --\u003e","brand":"RogMotorsport","offers":[{"title":"Stainless steel \/ No manifold","offer_id":60851687358798,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-INOX-SANS","price":2890.0,"currency_code":"EUR","in_stock":true},{"title":"Stainless steel \/ Catalyst-free manifold","offer_id":60851687391566,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-INOX-DECAT","price":3790.0,"currency_code":"EUR","in_stock":true},{"title":"Stainless steel \/ 100-cell sport manifold","offer_id":60851687424334,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-INOX-SP100","price":4210.0,"currency_code":"EUR","in_stock":true},{"title":"Stainless steel \/ 200-cell sport manifold","offer_id":60851687457102,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-INOX-SP200","price":4210.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ No manifold","offer_id":60851687489870,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-TI-SANS","price":3640.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ Catalyst-free manifold","offer_id":60851687522638,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-TI-DECAT","price":4540.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ 100-cell sport manifold","offer_id":60851687555406,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-TI-SP100","price":4960.0,"currency_code":"EUR","in_stock":true},{"title":"Titanium \/ 200-cell sport manifold","offer_id":60851687588174,"sku":"ROG-410-MASERATI-GRANTURISMO-V8-4-7-TI-SP200","price":4960.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/5079\/3806\/files\/ligne-echappement-titane-brosse-maserati-granturismo-grancabrio-v8-4-7-2008-2016-embouts-rog-noir-brillant.jpg?v=1793314796"}],"url":"https:\/\/rogmotorsport.com\/en-us\/collections\/exhaust-maserati-granturismo-grancabrio-m145.oembed","provider":"RogMotorsport","version":"1.0","type":"link"}
