Hi, I'm new here. I have a f master 40 with 2.25 piping and 3.5 inch tips, this may be a stupid question, but, it doesn't have that growly sound I was hoping for. Is there anything I can do to make it have that?

 

Mine had the same problem when I first had it done... has 2.50" in and 2.25" out I cut the pipes off going to the back and ran dumps much deeper tone and more throaty than last summer had all 4 cats removed and went with 2 high flows just to be safe that's what made the real difference so if I were you I'd gut the back 2 cats, at least big difference in sound
