You won't really get performance gains out of the axle back, because the factory midpipe is too much of a constrictor. Once you open the midpipe, then you will see the gains. As far as sound goes, it will definitely give you a louder exhaust note.

I'd jump on that new axle back...
I did enjoy the short tails with the s-line mid pipes, but did get loud and a tad annoying
when i just wanted to cruise with music on. lol

But it is out of my price range, would love to do some sound clips since
i have the Mid pipes and CAI from AAM. :D

Any updates on the 3inch system?

Also with the G37 sound clip, what other mods are on it?

I'm curious how loud this would be on my z with long tube headers...

We are working hard on getting the videos completed and posted. We will have a video of a G37 with long tubes, our s-line midpipe and axle back and the thing sounds amazing. I will post them as soon as they are done. Hoping to have them posted next week for you guys.

Put the new AAM axle back on today.

Sound clips coming soon.

It is true to their word, no drone, not loud, but enhances the stock VQ sound a bit, especially under load. Cruising off throttle etc it basically sounds stock, till you get into the throttle and it makes some nice noises. But again, it is not loud. I am going to pair it with a mid-pipe soon :)

Install was a breeze, and there is about 3lbs of weight savings, for those that are curious of those kinds of details.

Vids coming later this week.
