{"type":"firestarter.listing","listing":{"id":"lst_ABBZAmvX","product_name":"APR MK7 GTI Front Muffler (Optional)","category":"Exhaust","description":"The mufflers are responsible for tuning the exhaust note and do so without adding unnecessary restrictions to the system. Each unit features a straight-through perforated tube that’s tightly wrapped with stainless steel and fiberglass material. The mufflers have a beautiful satin finish, and are tucked high in the exhaust tunnel, making them perfect for lowered vehicles.  The system comes standard with a single muffler with the option of adding our front triangular muffler at any time. The system sounds deep, throaty, and devoid of rasp and drone in all configurations. The single muffler setup will be perfect for most customers, especially those with the factory downpipe. When upgrading the downpipe, or going to a larger turbocharger, the system gets louder. For those who want it quieter, our drop-in front muffler makes for an excellent upgrade.","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/products/d6bef1479c00de9a56e9d6f21f544e8e.jpg?v=1528290804","https://cdn.shopify.com/s/files/1/0024/4898/2060/products/f32961346443aac888b1dd88f31a968c.jpg?v=1528290804"],"price":349.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:21.616Z"},"share_url":"https://firestarter.network/l/lst_ABBZAmvX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
