The newest addition to our Signature exhaust range is the 4-1 Sports Manifold. Designed as a simple replacement for the original item and re-using the original heat-shielding, the Signature BB is aimed at those looking to further reduce back-pressure in their forced induction system. It’s careful design means that no modification to the subframe, mounting points or other exhaust components is required.
During performance testing, we found significant improvements in torque between 3800rpm and 6000rpm and peak power increases at around 8250rpm by as much as 15bhp when used with our Signature Sports Catalyst.
Compatible with OE Catalytic convertor or Signature Sports catalyst.
