{"product_id":"3-inch-single-cat-back-exhaust-system","title":"3-Inch Single Cat-Back Exhaust System","description":"The CPE 3-inch Single Cat-Back Exhaust is engineered for optimal flow and minimal back pressure, crucial for turbocharged vehicles like the Mazdaspeed 6. Custom Performance Engineering (CPE) designed this system with smooth mandrel bends and a specialized 12-inch oval muffler to reduce back pressure and encourage quicker turbo spool-up. Dyno-proven tests indicate a significant increase in horsepower and torque across the entire engine operating range.\n\nConstructed from polished 304 stainless steel, all tubing is manufactured in the USA by American Stainless Tubing, Inc. (ASTi), featuring a unique super buff finish. This cat-back kit comes complete with 3-inch tubing, the 12-inch oval muffler, an optional resonator, stainless steel band clamps, and a gasket designed to mate with the stock downpipe. The product description notes that dyno graphs provided compare a factory stock SPEED6 against a SPEED6 equipped with the CPE Cat-back and a 14-inch round resonator, with no other performance modifications made to the test vehicle.\n\nThis exhaust system is specifically designed for the 2006-2007 Mazdaspeed 6 models.","brand":"CPE","offers":[{"title":"Default Title","offer_id":52687478849848,"sku":"MZAE00003\/5T","price":708.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660687074.jpg?v=1784884671","url":"https:\/\/store.motormia.co\/products\/3-inch-single-cat-back-exhaust-system","provider":"MOTORMIA","version":"1.0","type":"link"}
