Best catback system for MS 6?

[hotknife]

Hi guys,

does anyone have any experience regarding the gain of HP and torque of the dual ss cat back system for MAZDASPEED 6?

cp-e claim round 30 HP if replaced against the serial system.

What about GHL or corksport? Increase of power is IMO more important than sound.

Thank you.

Take care.
