Hey I installed my V4 plenum and loved the sound it made but but now if seems that it has died away and I know its not me because i have a video of it when i installed it and now and you can deffinetly tell that the sound has died down. I would like to know if thats the way its supose to be or do you guys think somthing is wrong with mine.


thanks,
Josh

and also do you guys think the screw might have came loose?

 

not supposed to change sound. You sure it's not sensory adaption?

 

better check with the Doc!
