On a naturally aspirated engine its design matters: lengths and geometry affect cylinder filling at high revs. With a remap the gain is real but modest, in the order of 3 to 8 %. Badly designed, it loses 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\/audi-rs4-b8-v8-2012-2015-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-audi\" 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 Audi 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-audi-rs4-rs5-b9-b9-5-2-9-tfsi-v6\"\u003eRS4 \/ RS5 B9 \/ B9.5 2.9 TFSI V6\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/en\/products\/exhaust-audi-rs5-8t-v8\"\u003eRS5 Coupé \/ Cabriolet 8T V8\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eSee all the \u003ca href=\"\/en\/collections\/exhaust-audi\"\u003eAudi valved exhaust systems\u003c\/a\u003e.\u003c\/p\u003e\u003c!-- \/rog-maillage --\u003e","brand":"RogMotorsport","offers":[{"title":"Stainless steel \/ No manifold","offer_id":60851615039822,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-INOX-SANS","price":3301.0,"currency_code":"USD","in_stock":true},{"title":"Stainless steel \/ Catalyst-free manifold","offer_id":60851615072590,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-INOX-DECAT","price":4466.0,"currency_code":"USD","in_stock":true},{"title":"Stainless steel \/ 100-cell sport manifold","offer_id":60851615105358,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-INOX-SP100","price":5140.0,"currency_code":"USD","in_stock":true},{"title":"Stainless steel \/ 200-cell sport manifold","offer_id":60851615138126,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-INOX-SP200","price":5140.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ No manifold","offer_id":60851615170894,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-TI-SANS","price":4158.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ Catalyst-free manifold","offer_id":60851615203662,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-TI-DECAT","price":5323.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ 100-cell sport manifold","offer_id":60851615236430,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-TI-SP100","price":5997.0,"currency_code":"USD","in_stock":true},{"title":"Titanium \/ 200-cell sport manifold","offer_id":60851615269198,"sku":"ROG-046-AUDI-RS4-AVANT-RS5-COUPE-B8-5-4-2-V8-TI-SP200","price":5997.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/5079\/3806\/files\/ligne-echappement-titane-brosse-audi-rs4-avant-rs5-coupe-cabriolet-b8-5-4-2-v8-2012-2015.jpg?v=1793227545","url":"https:\/\/rogmotorsport.com\/en-us\/products\/exhaust-audi-rs4-avant-rs5-b8-5-4-2-v8","provider":"RogMotorsport","version":"1.0","type":"link"}
