Hello,
Can you please tell me what part number Flowmaster Super 44's you used for you exhaust install? If you do not know, do you maybe know the factory exhaust size for our 3.9 engines?

Thanks in advance for your help!!

p.s. Your exhaust sounds AWESOME ! Hopefully soon, mine will sound similiar.

 

What your going to need is 2.25" inlet/outlet dia. and it's offset inlet and center inlet

 

or just upgrade the piping ot 2.5" much better flow... and better to spend the money now then to redo it later.
