{"product_id":"competition-series-cat-back-exhaust","title":"Competition Series Cat-Back Exhaust","description":"The Stillen Competition Series cat-back exhaust is an engineered performance upgrade designed specifically for the 2023-2026 Nissan Z. Developed to address the tone-suppression inherent in the VR30 twin-turbo V6, this system utilizes a straight-pipe configuration without mufflers to deliver an aggressive, authoritative exhaust growl while optimizing overall exhaust flow.\n\nConstructed from durable 304 stainless steel, the system features 2.5-inch mandrel-bent tubing and precision TIG-welded flanges for longevity and corrosion resistance. A CNC-machined X-pipe serves as the centerpiece of the design, effectively merging the left and right engine banks to maintain performance without the flow restrictions often found in smaller mid-pipe setups. The system is further stabilized by a Stillen-branded reinforced cross-brace that provides additional chassis support.\n\nThis cat-back system is engineered and manufactured in the USA and includes a limited lifetime warranty.","brand":"Stillen","offers":[{"title":"Default Title","offer_id":52663852728632,"sku":"504500","price":973.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687715849.jpg?v=1784330164","url":"https:\/\/store.motormia.co\/products\/competition-series-cat-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
