{"product_id":"3-mode-valve-system-cat-back-exhaust","title":"3-Mode Valve System Cat-Back Exhaust","description":"The ARMYTRIX Valvetrix Exhaust System is engineered for a significant upgrade in both performance and auditory experience for compatible BMW M135i and M235i models from 2012-2015. The system boasts a 3-mode valve system, allowing the driver to seamlessly switch between a stealthy quiet mode and a more aggressive, attention-grabbing sound profile, all controllable via a smartphone app through the ARMYTRIX exclusive OBDII dongle.\n\nKey features include a 3-inch main pipe diameter and 2.5-inch tips, contributing to its performance gains of 17.1 HP and 24.8 Nm of torque, while also reducing weight by 1.3 kg. The system incorporates a catalytic converter and OPF fault code clearing mechanism to help mitigate check engine lights. Installation is designed as a direct bolt-on process, with a plug-n-play module that reduces installation time. The system is compatible with both Left-Hand Drive and Right-Hand Drive vehicles.\n\nIt is important to note specific fitment considerations. For the M135i, adjustments to the tailpipe may be necessary depending on the rear bumper style. Additionally, the quad-tips are only compatible with specific brands of diffusers; consultation is recommended before purchase. An ARMYTRIX OBDII Control Module is required for operation. Two versions of down-pipes are available, and buyers should verify fitment using their VIN prior to purchase.","brand":"Armytrix","offers":[{"title":"Default Title","offer_id":52686967767352,"sku":"BMF23-QS42M","price":3430.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660183744.jpg?v=1784879048","url":"https:\/\/store.motormia.co\/products\/3-mode-valve-system-cat-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
