lol pipe guy it is

 

2 ½” Inlet/Outlet Hooker Max Flow 521 CFM, I might have to try hooker Max Flow. How does it sound?

 

You'll find out Saturday, I'll post vids after system is installed

 

They should see what the CFM is on the Magnapacks and Bullets, seeing as they are the new hot items these days.

 

I'm hearing good thing about Bullets, who makes the Bullets? Does it sound loud?
