As with the standard size centre box systems detailed above, these two ‘bomb’ systems fit directly to the car’s original cast iron manifold (see cast iron manifold details). The ‘bomb’ centre box (actually more akin to a resonator) offers not only a sportier exhaust note, but also improved ground clearance, particularly on chrome bumper cars where the exhaust is naturally so close to the ground.

**Please note, these manifolds are not suitable for LHD vehicles**

Freeflow high efficiency stainless steel tubular manifold to fit chrome and rubber bumper models.
Fits directly to (and is included in) Rimmer Bros’ stainless steel sports exhaust systems without modification; will work with most other MGB exhaust systems, but probably with some degree of adaptation - anything from simply shortening the exhaust front pipe to finding a sleeve joint to use between the manifold and centre box - to fit it.

Product Description

MGB Exhaust Systems - Sports Stainless Steel with Bomb Centre Silencer - 4 Cylinder
Also including the RP1407SS tubular manifold are Rimmer Bros’ two sports systems with bomb centre boxes. The ‘bomb’ centre box offers not only a sportier exhaust note - further accentuated by the tubular manifold - but also improved ground clearance, particularly on chrome bumper cars where the exhaust is naturally so close to the ground.
