I just bought mbarrad's coupe midpipe and installed it on my sedan. The coupe pipe gives it a slightly more aggressive, slightly louder sound than stock. From what I remember of the coupe's sound, I'd say my sedan sounds just like it now. It was exactly what I wanted, not too loud or obtrusive but just a bit more growl. I'm not getting any of the droning that Mike was getting. It could have been due to his HKS muff that the combo didnt sound so great. There is a slight fitment issue in that the coupe resonator is right up against the heatshield below the driveshaft. Bending the hanger might do the trick. Interestingly enough, the contact didn'tt cause any adverse vibration. Attached is a link to before and after sound clips while running thru the 1st 2 gears. You will need to set up an account if you don't have one. I had my son in the trunk doing the recording. It is somewhat hard to tell the difference with the recording but it is.

Now I'll be pulling the pipe back off so I can do a baseline dyno, install all my planned mods and rerun it...Not til spring unfortunately.

Maybe a little...very tough to tell by the seat of the pants. It seems to rev a bit more freely.
