This BMW M135i came in for a DKU performance stainless steel exhaust system. After having the custom made exhaust system fitted, we also applied a DKU performance stage 1 ECU remap. With a DKU Performance stage 1 remap this BMW M135i was able increase its stock power from 315bhp and achieve the estimated figure of 365bhp along with the torque figures increasing from stock 450 ft lbs and achieving the predicted 520 ft lbs.
At DKU Performance we custom design for the full range of exhausts from a performance back box’s to cat back exhausts from the entry level exhaust to the premium level, and for the Motorsport players the awesome tubular manifold back and turbo back exhaust. They are all custom made in high grade 304 316 stainless steel.
