This is first I'm hearing of this. Think it would change an Ecoboost with CB Roush exhaust? I feel I get a lot of noise from the Airaid intake. It's louder than the ram air intake I had on my Dodge Ram. Would it reduce the intake noise?It does not do much for the GT if you have a aftermarket exhaust..it does help the ecoboost version sound better inside the cabin. If you do decide to take it out ,would be a good idea to plug the firewall ,never know rodents could try to get inside or something.
