The CTS Turbo Catless Downpipe for BMW B58 engines is engineered to deliver maximum performance by significantly increasing exhaust flow and eliminating the restrictions of the factory downpipe. Precision-designed using advanced CAD technology and tested in real-world conditions, it features a 4.5" opening tapering to 3.15" (80mm) for seamless integration with both factory and aftermarket exhaust systems. Crafted from premium T304 stainless steel with hand TIG-welded, back-purged construction, this downpipe offers long-lasting durability and a substantial power upgrade. The result is a noticeably more aggressive exhaust note that remains refined during cruising, with no unwanted drone when paired with the factory exhaust.
