Yep it was about 800 for me after they were installed and exact same issue, maybe they make our 40th's extra difficult lol. I'm glad you like it man the art pipes just make it so much deeper and louder, is it a lot louder for you? Still no drone? That's a nice setup man. I basically want/ have the same thing, only difference is I'm thinking about doing the AAM midpipe or going crazy and getting the Motordyne shockwave omg have you heard it?
