{"product_id":"full-downpipes-kit-w-200-cell-cats","title":"Full Downpipes Kit w\/ 200-Cell Cats","description":"The PLM Full Downpipes Kit is a high-performance exhaust solution engineered for the Infiniti Q50 (2015+), Q60 (2017+), and 2023+ Nissan Z equipped with VR30DDTT engines. By replacing restrictive factory components with 3.0-inch mandrel-bent stainless steel piping that transitions to 2.5 inches at the outlet flange, this kit helps unlock increased horsepower and torque. The system utilizes 100% TIG-welded construction for durability and includes 200-cell metallic high-flow catalytic converters to balance performance gains with exhaust filtration.\n\nInstallation is streamlined through the use of factory-style V-band flanges and OEM mounting tabs, allowing the kit to fit with stock turbos and most aftermarket cat-back exhaust systems without requiring extra hardware. The design includes J-style O2 sensor extension adapters, enabling the secondary O2 sensors to be installed in their original factory locations without the need for wiring extensions. This kit is compatible with both RWD and AWD drivetrain configurations and all trim levels.\n\nPerformance results depend on the base model, with reported gains of 50-60+ HP on 300hp models and 25-35+ HP on 400hp models. Each kit comes complete with necessary gaskets and hardware for a direct-fit installation.","brand":"PLM","offers":[{"title":"Default Title","offer_id":52663283482936,"sku":"PLM-V37-DP-CAT","price":750.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687525529.webp?v=1784325601","url":"https:\/\/store.motormia.co\/products\/full-downpipes-kit-w-200-cell-cats","provider":"MOTORMIA","version":"1.0","type":"link"}
