{"product_id":"grand-prix-gxp-stainless-catback-exhaust","title":"Grand Prix GXP Stainless Catback Exhaust","description":"The ZZPerformance Grand Prix GXP Stainless Catback Exhaust system is engineered for the LS4 Grand Prix, offering a premium, long-lasting exhaust solution.\n\nThe exhaust features mandrel-bent polished stainless tubing for optimal flow and a sleek appearance. The custom Y-pipe smoothly transitions from a 2.5-inch diameter to dual 2.25-inch pipes, culminating in double-wall polished stainless tips.\n\nThis specific model includes ZZP's exclusive stainless chambered resonator and mufflers, which the manufacturer highly recommends for all setups to achieve the best sound and performance characteristics. An option without a resonator is also available. The system is compatible with the 2004+ Grand Prix GXP model and does not fit the LS4 Monte Carlo SS. Shipping is via UPS only due to the oversized nature of the package.","brand":"ZZPerformance","offers":[{"title":"Default Title","offer_id":52664175755576,"sku":"ZZ-GXP-05-CBE-RES","price":799.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687545735.jpg?v=1784334737","url":"https:\/\/store.motormia.co\/products\/grand-prix-gxp-stainless-catback-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
