Inside stock resonator

[AZ_Ryan]

Not sure if s550 or s650.

I think there were 2 versions on the S550. The 2015-2017s were larger and supposedly more restrictive IIRC. Not sure which one is in that picture.

I'm 99% sure the S650 resonator is the same one from the 2018-2023 cars.

Do you still have that pic?

Are the mufflers different then? A lot of people talk about how much different the S650 sounds

All I know for certain is that mine is different, since I don’t have active exhaust like the Dark Horse test mule in the more recent video. Nor do I have what ever other improvements a DH has to get 500hp over my 480hp (whereas active exhaust GT’s have 486). It’s so tempting to get the H pipe as I may feel not only the 10 extra lbs ft at 2800 but also if the Roush axle back gave me the extra 6hp missing from not having active exhaust. Without real world testing, can’t ever really know.

I really didn’t want the active exhaust, since it’s more electronically controlled mechanical bits that can go wrong. So instead of spending the $1200+ for that option, I figured I’d do exhaust upgrades, like axle back/res delete.

I believe so. The S650 active exhaust mufflers sound very similar to the M1 versions to my ear. Those were different to the S550 GT mufflers.
