Has anyone tried this combo out on the S55?

Post a video if you did this!

Stock exhaust is pretty much a straight through when the valves are open. I've seen a customer with straight pipes and downpipes and it was extremely loud and raspy imo.

Here's an example of their Signature Kit with valves open (muffler bypassed), connected to ER Sport Cats.

The only way you could run a straight pipe setup would be to use resonated catless DPs, the AA Single Mid (but ask for resonated extensions), and then the straights (maybe with resonators there too). It's gonna be crazy loud, but double or triple resonators should take the rasp out.

Too raspy in my opinion, I recommend you use a quality muffler for the best sound

That's what I thought too, maybe with the single midpipe it would be deeper, but maybe not so much. I had the EL and Rear section from AA ordered through you guys, but got tired of waiting almost 4 months and thought I'll just leave it as is for right now.
