If you listen to @hockenheim_m2c on instagram it sounds pretty bad. I'm sure his was installed correctly....but if you listen to @am_m2c his sounds pretty good and clean.
Yeah.. exactly my point. I am not saying folks do or dont hear what they do.. I am trying to figure out WHY when my experience is different.

The single channel is and was very good, and now with the EL, I am very pleased so far. My observations are different than what others have reported in what appears to be a controversial subject, so the 'why child' in me has kicked in.

I will have a full, and I mean FULL video comparison setup as soon as I can..

It will be:

OEM everything - cold start, revs, driving
OEM DP, single channel, resonated and non resonated, stock exhaust - cold start, revs, driving
AA DP, single channel, resonated and non resonated, stock exhaust - cold start, revs, driving
AA DP, EL, resonated, stock exhaust - cold start, revs, driving
