Trust me something is off. I wish I had a gopro to post a sound clip. The rasp is only present during accelaration, so making a sound clip of me reving my engine in my driveway wont explain it. lol
I think if i go back to stock mufflers it'll go away, but it's only a theory and I'm trying to get some other opinions. At this point i'm not so much looking for loudness just a more refined tone. I appreciate your help
