{"product_id":"5-400cpsi-ultra-high-output-catalytic-converter-downpipe","title":"5\" 400cpsi Ultra High Output Catalytic Converter Downpipe","description":"The Unitronic Performance Downpipe is engineered as a direct bolt-on upgrade for 1.8TSI MQB EA888.3 FWD vehicles, aiming to significantly reduce restrictions in the factory downpipe. This enhancement leads to a noticeable reduction in turbo lag and an improved, more aggressive exhaust note. Central to its design is a 5-inch, 400cpsi ultra-high output (UHO+) catalytic converter, developed in collaboration with Unitronic and emissions partner Global Emissions Systems Inc (GESi), designed to meet or exceed local testing standards.\n\nConstructed with CFD-optimized upper downpipe castings and TIG-welded for durability, this downpipe maintains factory catalyst placement for optimal efficiency and retains the oxygen sensor provision. It includes an OEM-style corrugated mesh flex bellow and offers reducers for compatibility with both factory and upgraded cat-back exhaust systems. Hardware included consists of the downpipe assembly, two V-band clamps with centering rings, a stainless steel midpipe section, and a stainless steel exhaust reducer.\n\nTo achieve optimal performance and unlock maximum power gains, this Performance Downpipe requires Unitronic Stage 2 Performance Software and is recommended to be paired with other supporting modifications such as the Carbon Fiber Intake System, Charge Pipe Upgrade Kit, or an Intercooler Upgrade Kit.","brand":"Unitronic","offers":[{"title":"Default Title","offer_id":52872134590776,"sku":"UH074-EXA","price":3079.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/5-400cpsi-ultra-high-output-catalytic-converter-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
