High Flow Connection Pipes.

They feature KOOKS GREEN catalytic converters with a high concentration of precious metals to ensure effective emissions control, even in forced induction setups. The finish is a clean, natural stainless steel look designed for longevity and aesthetic appeal.

Installation. Installation requires compatibility with KOOKS long tube headers and the use of specific adapters to connect to OEM exhaust systems. No drilling is necessary, but professional installation is recommended to ensure proper fitment and seal. Clamps are not included.
