Replace your restrictive OEM cast O2 housing with our free flowing custom tubular model. Made completely from 304 stainless steel! The flanges are CNC machined from ½” material and are surfaced after welding for a leak free seal. The exhaust outlet measures in at 2.5” while the wastage outlet is 2.25" The wastegate passage of the flange is 3D contoured to match the shape of the turbine housing for a smooth transition.... a first of it's kind! Each unit comes with a machined ring for the OEM donut gasket and a stainless steel divided turbine gasket.

Screamer is for off road use only.

Install Tip: Removing the studs on the turbine housing will allow for a much easier install of the new housing.
