Invidia N2 sounds sooo good! I can’t get enough of it! Definitely increased the sound, but not overly loud. Gives kind of a mellow clean drone. Loud but reserved. Leans closer to a higher pitch. Idling can sound really loud at times but that was expected. When windows are up I can still take calls through car play and noises aren’t a bother. The exhaust is lightweight and looks great. Burnt tips looked nice with the Subaru emblem, and a fan of the welded Invidia plate on the split of the dual exhaust. Great purchase! And was delivered fast.
