{"product_id":"3-catless-downpipe","title":"3\" Catless Downpipe","description":"The RPMMotorsports Catless Downpipe is engineered to address the exhaust system's largest restriction on 2.0T LTG powered Cadillac CTS vehicles: the factory catalytic converter. By removing this restriction, the downpipe allows exhaust gases to flow more freely, reducing back pressure and improving turbocharger spool time. This results in increased torque at lower RPMs and helps lower cylinder head temperatures, mitigating the risk of knock retard, detonation, and piston wear during extreme use.\n\nConstructed with a full 3\" mandrel-bent piping, this downpipe ensures unrestricted flow without pinched areas. It features precision-milled 1\/2\" flanges for a secure and long-lasting fitment, and includes a lower support bracket. The ceramic coating provides added thermal properties, helping to keep engine bay temperatures down.\n\nAn ECU tune is recommended to maximize the gains from this catless downpipe. If not paired with an ECM tune, an optional Ecotec O2 Extender is available and specifically designed for the LTG motor. This extender helps to relocate the O2 sensor, preventing check engine lights and CAT overtemp fueling issues.\n\nFitment is specified for 2014+ Cadillac CTS 2.0T models, with specific application for 2015-2017 Cadillac CTS 2.0T models.","brand":"RPMMotorsports","offers":[{"title":"Default Title","offer_id":52663551033656,"sku":"CTS20TCATLESS","price":280.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687658229.jpg?v=1784327952","url":"https:\/\/store.motormia.co\/products\/3-catless-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
