I'm looking to unclamp the tail section of my oem 08 FX4 Screw exhause and replace it with just a muffler and a turn down. I am going to use the Dynomax Ultraflow round muffler in 23" length because I have used them a couple times before and love their sound.

What is the stock pipe size? Any other suggestions on materials?

Thank you in advance!

 

2.5", stainless steel clamps and a hanger and you will be good.

 

Awesome. Thank you sir!
