Description<\/h3>\n\n\n\n

Premium valvetronic catback exhaust system for BMW F30 340i B58 3.0T inline-six turbo. T304 stainless steel build, reduces backpressure, boosts B58 performance, delivers deep sport sound with bolt-on installation.<\/p>\n\n\n\n

Product Description<\/h3>\n\n\n\n

The factory exhaust system for BMW F30 340i B58 3.0T features restrictive muffler internals and strict OPF\/GPF tuning, causing excessive exhaust back pressure, dull throttle response and flat, quiet stock sound. Our upgraded valvetronic catback exhaust is tailor-made for the legendary B58 turbo engine, unlocking latent performance and pure sport exhaust tone.<\/p>\n\n\n\n

Crafted with high-quality 304 stainless steel and mandrel-bent seamless piping with precise TIG welding, this exhaust boasts excellent high-temperature resistance and anti-rust durability for long-term street use. The optimized high-flow pipe structure greatly reduces exhaust resistance, accelerates gas discharge, improves turbo spool speed and delivers noticeable horsepower and torque gains. Equipped with wireless remote control valves, it switches between quiet daily cruise mode and aggressive racing mode, eliminating annoying highway drone. All OEM mounting points and sensor ports are reserved for 100% non-destructive bolt-on installation with no cutting or modification.<\/p>\n\n\n\n
