However I can tell you all this:

- Secondary cats are basically in the same spot as the M50 (no surprise)
- Resonator has armor/ heat shielding/dampening around it - cannot tell if X or H pipe
- valvetronics are mounted in a good spot - up under the rear bumper well
- exhaust tips are mounted/attached to rear bumper (not ideal)
Based on the layout in place the shop recommended the following for a good sounding solution:
- pay ~$4-$5K for an axle back/catback system with install
- Have a custom exhaust built - also not cheap. TBD, ballpark of $2-$3k.
- Leave main resonator (X/H Pipe), delete muffler and add a high flow resonator on each exhaust by the tip in place of the stock muffler. Approx $400.
Doing this last option they recommended keeping the stock muffler so as to be able to return to stock if I want.
This is the first S68 they have seen so they cannot give me an idea of what it will sound like, but given the added resonators creating a more refined sound vs straight pipes. All in all they felt like it would sound very close to the M50 with a muffler delete. The resonators are basically a safety net to prevent:
- A fart canesque noise
- Too loud of an exhaust, especially on start up
By not removing the X/H pipe I will lose additional burbles that typically come with an aftermarket X pipe. IMO I am ok with this because I do not want an excessive amount of burbles that sound awful AND I by keeping the stock resonator I will not have to worry about drone or a bunch of extra cabin noise.

Wow, this is great information and thanks for taking the time post.
I am sure that there are others here who will be interested also.
Choice #3 above looks very appealing.
What are you going to do here?
