LOL! One of those "doh" moments with the JBA mid pipes...they were a total waste. They would make a nice set of off road pipes if I cleaned out all of the cat media that is broken internally. Double check to make sure all of your connections both electrical and air intake related are snug and correct. Take it off and reinstall everything there if you aren't sure to double check. Check out the rpm limiter to make sure you aren't bumping into the 6K-6.2K rev limit. Sounds like the same sound when the PTM engages which happens in PTM 1,2,&3 especially. Any check engine lights?
