Running the 40s as well? I only ask, because from my experience we had to turn the volume up louder than before and had to talk much louder than before to make the conversation entirely audible.

 

Yes with 40's and 2.5 pipes with longtubes just like i said in the beginning.I didnt change it in one day.Im not saying u can whisper but u can definitely talk

 

I'm dumping my Hooker Aero Chambers in front of the axle and it's not too loud. I'm not a fan of Flows though, they sound ok, but everyone has them and their performance sucks compared to some of the other mufflers
