I have two flowmasters with very low miles. Too loud for my taste. One is a american thunder duel 3" in and single 3" out
The other is a Force II duel 3" in and single 3.5" out.
I also have the tail pipes for these.
I had both of these on my truck and they both scream at WOT. the bigger forceII is quieter at cruise.
Email me and I can send pics, make me an offer, they are just collecting dust in my garage.
