{"product_id":"m177-w213-e63s-high-flow-catalytic-converters","title":"M177\/W213 E63S High-Flow Catalytic Converters","description":"The CTS Turbo Mercedes-Benz M177\/W213 E63S High-Flow CATS are engineered to significantly increase exhaust flow, leading to maximum power gains for your vehicle. Designed with the latest CAD technology, these high-flow catalytic converters are made to seamlessly replace the restrictive factory catalytic converters, ensuring a perfect fit.\n\nConstructed from durable cast T304 stainless steel, these downpipes are hand TIG welded and back-purged to guarantee years of reliable performance. The 70mm\/2.75\" stainless steel piping and quality construction contribute to both performance and longevity, fitting within OEM heat shields for a clean installation.\n\nBeyond performance, these high-flow cats enhance the exhaust sound, providing a louder, deeper growl with more pronounced \"crackle\" on downshifts and a confident \"punch\" during upshifts. The sound becomes even more pronounced when paired with an aftermarket exhaust system.\n\nFitment is specific to the 2017-2023 Mercedes-Benz E63S AMG (W213) with the M177 engine and the 2017-2020 Mercedes-Benz AMG GT 63\/63S (X290) with the M177 engine. Please note that to avoid a Check Engine Light (CEL) that will occur after installation, proper stage 2 tuning software must be used.","brand":"CTS Turbo","offers":[{"title":"Default Title","offer_id":52867526328632,"sku":"CTS-EXH-DP-0031-CAT","price":1699.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687952144.webp?v=1787911674","url":"https:\/\/store.motormia.co\/products\/m177-w213-e63s-high-flow-catalytic-converters","provider":"MOTORMIA","version":"1.0","type":"link"}
