Show original supplier description
The Milltek Sport SSXM411 is a non-resonated cat-back exhaust system designed to enhance both the performance and sound of your MINI Cooper S or JCW F56/F57. Constructed from 2.75" T304 aircraft-grade stainless steel, this system is built for durability and resistance to discoloration, featuring mandrel-bent pipes for unrestricted gas flow and increased bore size to maximize performance without losing low-end torque. This exhaust system comes with a choice of Dual Round 90mm GT90 tips, offered in either a polished finish or a Black Cerakote for a distinct look. Milltek Sport is known for its superb sound quality and build craftsmanship, ensuring a significant improvement over the stock exhaust. The non-resonated design contributes to a louder, more aggressive exhaust note.
