Let me know how you like your Airdog when ya get it installed.....

 

I will, waiting on taxes now and bandageing mine to make it work.

 

Yes, if your friend just got one and it is still loud, then he bought it from someone that had old inventory on hand. I have a few customers that had them on older trucks, and have recently put them on newer trucks, and they can't believe how much more quieter they are now.
