I purchased a set of these Equal Length Headers in 2022 along with a Stage 3 tune. Not only has this drastically improved my M5 (6speed) with low-end torque, but working with Salman was a great experience. Despite the different timezones (I live in Canada) Salman always made time to answer questions and made doing business as easy as if he were down the street. I will 100% do business again with Infinity Design and Salman, I'm working toward the single piece plenum and air intake next. Thank you!
