Everything I was expecting and more. Installation was a breeze, the only thing I was missing is the three screws for the top cover. But overall it looks great and sounds even better when you need that extra power.

After only a few days and on my first empty road trip egts are down about 100 degrees but the ambient has also dropped. After running hard for 3 hrs cool down to 350 from 625 was much quicker but again it is only 30 degrees out. Once back into summer and rv season I will be able to better compare before and after.
