The exhaust is not louder than the intake. The exhaust has a smooth deep sound, and you don't hear it inside like most.
phish - I pm'd you back.
But for everyone else around these parts...
What JB said is correct - the exhaust is not louder than the intake. The Gibson gives off a slight rumble and no drone. In my opinion, it's perfect.
Oh, and I don't know if I'm just imagining things, but I swear the Gibson exhaust actually made the Injen CAI quieter!! I put the Injen on about a week before the exhaust and could have sworn it was louder before the exhaust.
Good luck phish - let us know how you like it.
