{"product_id":"e92-e93-m3-performance-cat-back-exhaust-system","title":"E92 \/ E93 M3 Performance Cat-Back Exhaust System","description":"The Eisenmann E92 \/ E93 M3 Performance Exhaust is a highly regarded rear exhaust system specifically engineered for BMW's naturally aspirated S65 V8 platform in the E92 and E93 M3 models. It is designed to provide Eisenmann’s signature sound, characterized by a deep, refined tone at lower RPMs that escalates to an unmistakable V8 scream during acceleration. This exhaust system is available in two distinct sound levels: Sport and Race, allowing customization to individual driving preferences.\n\nThe Race version offers a deeper, more aggressive exotic tone and provides documented performance gains of 16 horsepower and 11 lb-ft of torque. The Sport version delivers a more refined exhaust character while still enhancing the sound and flow compared to the factory system. Both versions feature a 25% flow improvement over stock for the Sport model and 32% for the Race model.\n\nConstructed entirely from 100% 304 stainless steel and meticulously handmade in Germany, this exhaust system includes connecting pipes for a direct bolt-on installation, eliminating the need for cutting. The standard finish is stainless steel, with an optional Black Series upgrade offering a high-temperature matte black ceramic coating that enhances corrosion resistance and heat dissipation.\n\nKey specifications for the Sport version include a moving vehicle sound level of 75 dB and a stationary sound level of 92 dB at 6,225 RPM. The Race version produces approximately 95 dB moving and 102 dB stationary at 6,225 RPM. The approximate muffler weight for both is 21 kg. The product details confirm it is designed for the BMW M3 (E92 \/ E93) and is available with 4x83mm round tips. Professional installation is recommended, and buyers must select their desired tip style and sound level before ordering. An emissions compliance notice should be reviewed.","brand":"Eisenmann","offers":[{"title":"Default Title","offer_id":52687930327352,"sku":"B5267.00835KT","price":2839.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664195916.webp?v=1784887661","url":"https:\/\/store.motormia.co\/products\/e92-e93-m3-performance-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
