I've got the M Performance intake which maybe sounds a little louder than stock because it has an extra air intake hole in the bottom of the air filter box. (That hole faces forward.) I use a drop-in aFe Pro Dry filter. Now I'm curious to see if I notice any sound difference.
Please post before and after logs if you can. I'm very curious to see if you have the same increase in MAF readings and how much they differ from 5000 RPMs on up. I haven't recorded a log but I may give it a try so that I have some "before" data before my installation.

You may not notice much of a sound difference with the stock air box.. too much built in sound baffling.
Logs are above.. as you can see, my results were useless.
