Cobra Sport Review

Cobra Sport have worked hard to secure a first class reputation amongst BRZ owners and tuners both in the UK and worldwide. Building upon this success, Cobra Sport are pleased to announce the launch of their latest development for the BRZ, consisting of a 4-1 de-cat manifold.

The de-cat manifold has been designed with unequal length sections with optimised lightweight pipe lengths and angles. This precision engineering improves gas flow efficiency by removing the catalyst at the most important part of the system for overall performance improvements. This improvements in flow dramatically reduces the effects of torque dip experienced by many BRZ owners and is optimized for further power increases through engine tuning. During testing, the BRZ passed the MOT emissions test with the Cobra Sport manifold fitted as long as either the standard cat or Cobra Sport high flow catalyst is in place.

The Cobra Sport BRZ manifold produces a deeper more aggressive exhaust tone. The acoustics of the de-cat manifold have been finely tuned to complement the tone of the extended Cobra Sport range for the BRZ offering the ultimate upgrade in terms of possible power increase and pitch perfect exhaust tone.
