Exhaust Akrapovic Evolution BMW 4 CONVERTIBLE 440 I 01-18

Evolution exhaust systems for BMW are the result of the perfect integration of experience, technology and use of the best materials. Crafted from austenitic stainless steel, these systems feature a newly developed layout with two central link pipes replacing the single tailpipe, a new muffler design and carbon fiber tailpipes. The elegance of this product makes the Bavarian car different from the others and offers the taste of a more "muscular" version, accentuated by the power gains and weight reductions that the Evolution exhaust guarantees. The adoption of the ECU controlled dual-mode valve offers a normal sound level in traditional driving while using the 340i dynamically, it offers a much deeper and more enjoyable sound. The Evolution system replaces the stock exhaust from the catalytic converters. ATTENTION: both codes MTP-BM/SS/2H and E-BM/SS/2 must be ordered. They were simply separated for packing and shipping reasons. FITTING NOTE: this kit does not fit on cars equipped with Otto particulate filter (OPF.)
