June the 23rd we received the BMW E82 1 series 1M Coupè for the development of a full exhaust system,
after a trip that brought it from the UK to the Nurburgring, then to the KW Suspensions factory and finally to our facilities.
As usual, we tested it on the MAHA dyno, with very good results, 359 hp, compared to the conservatively claimed 340 hp.
The Supersprint system has less restrictions, different downpipes with no cats, HJS sport cats placed downstream, under the car, a centre silencer and a transversal rear exhaust with dual round, 80mm, slash cut endtips.
The quality and good design of the new system brought a healty gain: 370 hp and 544 nm of torque were the final results of the dyno testing.
The system availability is still to be confirmed, probably in October. Prices, videos and components pictures availble soon in the
