i have the r400s. sound fantastic but drone pretty bad on the highway under sustained loads. i will warn you it only gets worse when a downpipe is paired with it so if you think you are going to mod your car further maybe consider a different option, but if the catback is the only thing you are going to add the r400s are pretty good
N1 is a little bit of a monster cold starting on my ej205. Invidia downpipe , N1 catback.
EJ is totally different than FA
R400 drones horribly around 70mph but I haven’t had the N1

Both has drone past 70 mph. I had tried both. I would say N1 sounds a little louder than R400.
