I need a 4.5 to 3" or a 4.25 to 3" silicone reducer and i cant find one anywhere...

 

Pull your charge pipe and weld a reducer to it to fit the coupling. I saw your build thread. If the coupling is 4.5" to 3.5", weld a 3.5" to 3" reducer to the pipe and the coupling you have will fit. I'm not sure what you are running right now.....

 

its actually the coupling off of my fipk filter i had on it, it has a reducer sleve in it so its sealed

 

Oh ok. Sorry about that. It just looked like it wasnt sealing all the way.
