Correct, the "mid-box" is an x-pipe and "sound tuner" all in one..

wouldn't it be more h-pipe?

It's neither. The midpipe is closer to a baffled chamber.

Is that what the rubber flap is for? It's only on one side not the other.

Looking at the photos again, it would appear so, in which case it will be a smaller piece that has to be loosened and dropped.

When doing the exhaust on my 2010 I found that staggering the mid mufflers decreased hollow and drone. I think that resonator does the same thing. The path of one exhaust is different than the other this helps keep sympathetic frequencies from reinforcing one another.

Interesting, so what is the actual purpose of the resonator box?

Is it put in place to change the sound of the exhaust like some sort of tuned exhaust device?
Or is it supposed to change the torque curve in some manner like H-pipes & X-pipes are supposed to do?
Or is it just to quiet the exhaust by acting as some sort of pre-muffler and allow the car to be quieter than it would be without the box?

By looking at the patent diagram the design looks like some sort of silencer, similar to what is utilized by firearms to lower the downstream noise level. To me it seems to be the most likely because the patent document specifically mentions "expansion chamber".

interesting. thanks!

isn't that what resonators are for anyway? (well decreasing pressure or something?)

Resonators are for sound only. The current 5.0 is very raspy and loud w/o them.

Worse when the cats are removed.

Would that resonator account for the distinct bark we heard in Goodwood when the 5.0 with the FRPP axleback was making its run? I've never heard an H or X-pipe setup sound like it before on any S197 with a Coyote. The exhaust pulses sound more... trumpet-like for lack of a better word.

wait, have we confirmed the use of the FRPP axleback at goodwood? also isn't a catback?

I just went back to that CJ vid. You're correct, he said it was the FRPP catback. I just assumed it was muffler + tips. They sound a little different, but one's under load and the other is at a standstill.

That would be a lot more easy that taking that whole under shield off. It doesn't look like it would tilt down either and actually looks like it may be attached to the front splitter as well.

I thought so, an axleback would require a saw

Just like the challenger. This is the best bang for your buck everyone asks what cat back I have and they are stunned when I tell them It's just the Reso delete.

Pretty much a SLP Loudmouth. Two simple cuts and two clamps or a weld.
