HKS SUPER MANIFOLD with CATALYZER GT-SPEC GR86 BRZ 33005-AT010

SUPER MANIFOLD with CATALYZER GT-SPEC

 

Highly efficient metal catalyst and 4-2-1 equal length layout provide excellent exhaust efficiency

 

 

■ Features

• Unlike the fine-mesh ceramic catalyst used in the factory, this product uses a low-density metal catalyst, which significantly reduces exhaust resistance.
• Although it uses low-density cells, it optimizes the ratio of precious metals and complies with the 2018 exhaust gas regulations. It has been certified by a third-party organization.
• Adopts a 4-2-1 isometric layout. After extensive consideration of the layout of the four sections, a completely isometric layout has been achieved.
• The head side flange has been redesigned to improve the step at the pipe insertion area, and a newly designed flange has been adopted.

■ Output comparison

↑
At 4300 rpm, the power output difference with the standard vehicle is at its maximum,
with power output increasing by 10.2 kW (13.9 PS), and torque increasing by 22.5 Nm (2.3 kgf･m)
Both　are improved by approximately 11% .

 

 

This is a comparison of the power output of different manifold and muffler combinations.
When this product was combined with Hi-Power SPEC-L II (32016-AF101), an improvement in power output was confirmed across the entire range.
The difference was particularly large in the mid-range, and the drop in torque around 4000 rpm was significantly eliminated.
When comparing a stock vehicle with an HKS manifold and muffler combination, the maximum power output increased by 10.2 kW (13.9 PS) and 22.5 Nm (2.3 kgf･m) at 4300 rpm.
