This is a little overview of the second and final step of reducing noise project in my STi. Thus, after covering my hatch area with brownbread material, time has come to complete everything with a layer of Ensolite wherever possible:
"So what is the result?" — some may ask. On a scale of 1 to 10, I'd rate this result as probably 5. The deep base did not diminished significantly, but did to a point where I can live with it and don't need to install OEM catback back. However, in the future I do see a quieter exhaust, something similar to MadDad Whisper.
