{"product_id":"200-cell-race-catalyst-downpipe","title":"200-Cell Race Catalyst Downpipe","description":"The Milltek SSXAU605 is a large bore, stainless steel cast downpipe engineered to enhance gas-flow and heat management for increased efficiency and performance gains on Audi TTS MK3 Non-GPF models. This performance downpipe incorporates a 200-cell race catalyst, which is considerably less restrictive than the standard OEM catalysts (typically 500-600 cells), resulting in improved exhaust gas flow and enhanced engine performance.\n\nConstructed from T304L stainless steel, this downpipe is designed for a direct fitment using OEM mounting points and hangers, requiring no modifications for installation. Its 3.00-inch (76.2mm) diameter further contributes to optimal gas flow.\n\nCrucially, the Milltek SSXAU605 is designed exclusively for fitment with the OE (Original Equipment) exhaust system only. It also mandates a Stage 2 ECU remap to ensure proper operation and to fully realize its performance potential. This product is intended for vehicle modification, and its use may be restricted to off-road or competition purposes depending on local regulations.","brand":"Milltek","offers":[{"title":"Default Title","offer_id":52689135370552,"sku":"SSXAU605","price":689.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687384829.jpg?v=1784902356","url":"https:\/\/store.motormia.co\/products\/200-cell-race-catalyst-downpipe","provider":"MOTORMIA","version":"1.0","type":"link"}
