Has anyone heard a 289 with the Flowmaster 10 Series mufflers on it? I'm trying to decide between 40 series and 10 series. I've heard 40's on a 289 but not 10's. The 40 is a two chamber muffler and the 10 is a single chamber. Any suggestions or links to a youtube video would be great (i couldn't find any 289's with 10 series on there).

Flow master 10's are loud, I honestly think they dont do anything at all. Its kinda like having open headers but I believe the 10's make it street legal.

Im a fan of the 40's, it screams muscle!

I have numerous people say my original 40 series are too loud.

The 10 series are not street legal and are race mufflers. However, some inspection places don't care.

It will be obnoxious and you will attract alot of attention from the cops. I wouldn't do it.

What have you done to your 289 to warrant a race-only muffler?

The single chamber is going to be wicked loud. I have a freind who put one on his 1974 Alfa Romeo GTV with 300 horse power and it was loud. The 40 Series are plenty for a street car.
