Sounds like an old school V8 like the amg 6.3.

The thing Is, the mustang has the cross over right after the cats when the pipes converge.
The Camaro has the cross over at the end of the exhaust system so all that vibrating straight pipe is ocilating the rasp.
I dont know why Chevy did that, maybe packaging purposes?

My best bet is for resonators where the secondary cats are, and an h where the factory x is.
I kinda got used to having these 2 cars sounding different, I have an h pipe laying around but idk if I want to take away the camaros Nascar sound at higher revs.

I agree, they should have put the X-pipe after the cats....
