European Auto Source has released a video showing the installation of a BMS N55 Catless downpipe and JB4 in a BMW E90 335i. The modifications in this BMW include AFE intake, Burger Motorsports 3.5 inch Catless downpipe and JB4 Tune stage 2 for N55 variants and VMR 19 inch V710 wheels finished in gunmetal polish.
EAS reveals the easiness of making a substantial gain of power with the bolt-on modifications by simply swapping the restrictive stock intake and downpipe with free flowing replacements. This E90 N55 335i gained 44whp and 75wtq.
