{"product_id":"t304-stainless-steel-downpipe","title":"T304 Stainless Steel Downpipe","description":"The CTS Turbo High-flow Cat is engineered to unleash the full potential of BMW N55 engines with electronic wastegates, maximizing exhaust flow for significant power gains. Designed using CAD technology, it ensures a perfect fit as a direct replacement for your factory downpipe. The construction utilizes robust T304 stainless steel, expertly hand TIG welded and back-purged to guarantee years of reliable performance.\n\nKey features include precise design and rigorous real-world testing, a direct replacement for the restrictive factory downpipe, and the ability to deliver substantial power increases without sacrificing performance. This high-flow cat also produces an exhilarating, sporty exhaust sound that remains subtle during cruising and eliminates the drone often associated with aftermarket exhaust systems.\n\nTo avoid a check engine light (CEL) and ensure proper operation, Stage 2 software is required. The use of Bootmod3 downpipe software upgrade is strongly recommended. This product is intended for OFF-ROAD use only. Catalytic converters damaged by “crackle tune” are not covered under warranty. It does not fit RHD (Right-Hand Drive) vehicles.\n\nThis high-flow cat is compatible with the following BMW models: F30 335i \u0026amp; 335xi (production date after 07\/2013), F20\/F21 M135i \u0026amp; M135xi (production date after 07\/2013), F32\/F33\/F36 435i \u0026amp; 435xi (2013+), F22 M235i \u0026amp; M235xi (2013+), and F87 M2 (2015+).
