Changing from stock mufflers

[scrinch]

Will keep those RPM's up there.

I gather you are saying that the TFI would not be a bad investment no matter what. so when my SS checks start coming next month I am on it. Then I can also go back to my other mufflers that I love the sound of. Quiet is OK in Church and the library but not on a Harley

I think you'll see a difference with the added fuel the TFI gives you.
