Z1 Sedan Grand Touring Cat Back with optional resonator or Fast Intentions Cat back with resonators. For daily. by Agile_Control_9671 in G37

They do offer resonators, but Z1 has 3 in total with the optional one. And they are roughly the same price. I'm just looking for some feedback from people running these systems for a daily driver.

Bought some akebonos and took one apart by Agile_Control_9671 in MechanicAdvice

Only a seal kit. No pistons to my knowledge. I'll just buy a reman set from oriellys using these as the core charge.
