This BMW 135i N54 came along to our workshop for a DKU performance stainless steel exhaust system. After having the custom made exhaust system fitted, we also applied DKU performance stage 1 ECU remap to the vehicles. With a DKU Performance stage 1 remap this BMW 135i was able increase its stock power from 307bhp and achieve the estimated figure of 370bhp along with the torque figures increasing from stock 400 ft lbs and achieving the predicted 500 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.
