250Cup 4-1 Manifold & HJS HD 200cell Catalyser

What makes the perfect supercharger install manifold? All Stainless 304/316 construction. 10mm thick Stainless head flange with laser-cut expansion slots and zero distortion after welding. Stepped primaries - not too long/not too short. Longer than this design will cost you power! A quality hand-built/TIG-welded merged collector (not pressed tin!). COMBINED WITH THE 130MM DIAMETER HJS HD 200Cell CATALYSER.


Independently tested against other aftermarket offerings, the 2bular 4-1 gave best power AND torque.

I supply a NEW 1st Lambda sensor to ensure your new HJS HD catalyser is protected and your motor can achieve full performance. I only use Bosch sensors -same as the factory. Also supplied is a gasket for the cylinder head/manifold join.

Lead time for order: 2 weeks.
