So far, I've owned both the MAP and JLT and rode in an Airaid equipped car. The MAP is the loudest by far. Between the metal piping and filter placement in the fender, it's very audible and loud. That's not saying that it's a bad thing, but some prefer not to hear the induction noises as much as others, lol. The JLT is semi-loud, I guess you'd say. You can still hear it under throttle, but while cruising, I don't much notice it anymore. When you punch it though, you'll hear it, but it's not overbearing. The Airaid is the quietest I've heard and that's probably because it's inside a completely sealed box whereas the JLT seals against the hood. On a ten scale rating for loudness, I'd rate the MAP around a 8-8.5, the JLT around a 5-5.5, and the Airaid around a 3.5-4.
Not that I've seen. Unless you had a really good microphone mounted close to the hood or was under a decent amount of throttle, I don't know that a microphone would even pick it up. It's very quiet when you want it to be and can be louder than stock, if desired (by throttle input).
Hmm... Anybody in SE lower Michigan have a CAI installed that I can listen to?
No, you block off the port where it would re-circulate to make it louder. Or you can use your stock recirc hose and its a bit quieter. I would post up a vid, but all you can hear in it is my exhaust and the BPV venting to atmosphere. JLT really just sounds like more air wooshing into the turbo, which you cant really pick up with a vid from inside the cabin. Would have to have a microphone under the hood or something.
If you are capping it off, you are supposed to. It's just unneeded tubing that is getting in the way
I ran it for a day with it off. Now trying it with it installed. There really isn't much of a difference in the sound. Maybe just a bit quiter on the release with the tube installed.
What did you go with in the end? On or off?
It's still installed right now. I have a service appointment coming up so I decided to leave it on. It sounds good either way.
