This is the same muffler I run on my 306, but the poor tbi can't quite make it scream. Gave it a very deep tone, not too much louder than stock. ROG2 is not a good phone for video so the quality isn't great, I'll probably take another video once the muffler's a bit broken in.

It's getting a bit louder as it breaks in, but it's not as loud as the one I have on my F250. That's got a Blueprint 306 with long tubes and 3.5" pipe, plus it can rev a lot higher than the TBI can.
