Revolution 86 / BRZ Exhaust manifold catalyzer set

Car Make: Toyota
Model: 86 / BRZ MT / AT
Product code: RZN6-ECS

All stainless steel 42.7-50-54φ, exhaust manifold without the first catalyst.
Replacing the exhaust manifold, which is the bottleneck of the exhaust system, will increase the torque from 2500RPM and reduce the valleys at 4000RPM.
The power rises by about 12 to 15 HP to the peak, and you can experience the effect after replacement in combination with the engine response.

The genuine first catalyst is abolished, and while achieving high exhaust efficiency, it complies with the strict exhaust gas regulations of recent years.
For installation, cut the genuine second catalyst part and use a genuine silencer.
The rear muffler can also be used with products from other companies that have passed the acceleration noise test.

* This product cuts the genuine second catalyst, but uses a special exhaust band, so it can be returned to genuine by bolt-on without the need for welding.
