The 2nd generation BMW Z4 (E89) 28i with the turbocharged N20B20 engine is claimed to be able to produce 241hp and 350Nm of torque by the manufacturer.
With the SUPERCIRCUIT cat deleted downpipe, the turbo will spool faster and at least extra 10hp gain can be expected.
The SUPERCIRCUIT catless downpipe is designed to be able to bolt-on straight to the factory stock turbo outlet and is 100% compatible with the rest of the BMW Z4 exhaust system.
The SUPERCIRCUIT downpipe for the BMW Z4 28i (E89) is made of oversized grade 304 stainless steel mandrel bent pipes and full TIG/Argon welded.
At the turbo end, the SUPERCIRCUIT BMW Z4 downpipe flange is made of CNC machined stainless steel to ensure perfect fit.
At the other end of the downpipe, it is a slot-in joint connecting the downpipe to the rest of the BMW Z4 exhaust system (a.k.a. catback exhaust system). Just straight bolt-on, no cut or welding is required for the installation.
