Why do that when you can ask MFR to do the same thing?
You also have other exhausts like the Morton Inferno's that not many of us have, you can see pictures of them in my album, I don't have the link to the website here at work but if you look at my pictures and want the link I can post it when I get home.
If a set from MFR are your 1st choice that's what you should do. I spent a ton of money on mods that I skimped on then gave away or sold them cause it wasn't truly what I wanted !! I have a set from Mike & when I tire of them I hope he'll build me another set
