Fujitsubo’s Super EX manifold combines premium Japanese craftsmanship with modern engineering techniques to create one of the highest quality manifolds currently available. Since 1931 Fujitsubo’s motto has simply been “produce the highest quality products” and this shows through with these exceptional manifolds. The attention to detail is second to none, even down to the use of lightweight press folded flanges instead of heavy machined block flanges.
Each manifold is made from SUS303 stainless steel and is TIG welded throughout. Where hangers are needed, stainless hollow piping is used to maintain the lightest weight possible and instead of being welded directly to the piping, every hanger is first welded to a base plate before being attached to the main exhaust to spread the load and prevent fatigue. Where the manifold joins to the included de-cat, Fujitsubo have added a Flexi doughnut joint with sprung bolts to ensure engine vibration is absorbed and not transferred to the rest of the exhaust system. The sprung bolts play a part in absorbing vibration but also help to keep the nuts tight.
Their NA 1.8 manifold is a beautifully made 4-2-1 manifold with some of the biggest runners we’ve seen, going from 42.7mm to 45mm to 50.8mm respectively.
