I'm not a fan of catless combined with Corsa Extremes or Roush. It's not only loud but harsh. Sounds like metal grinding together.

Corsa Xtremes sounded great when stock but got way too trumpety when adding long tubes in my opinion. A pair of Vibrant 1794s helped that some but ended up chopping off the Corsa mufflers but kept their double x and added AWE Touring mufflers. Screams up top, no trumpet tone, and has more character in the lower rpms than the Corsas did.

The MBRP Street the previous owner put on this, with its H pipe setup, sounds real good. When it starts up cold it's pretty neat. Went through a small tunnel recently with the windows down and boy did it sound rowdy.

Out of curiosity, what's the Coyote firing order? And how about the GM LS/LT 6.2L engines, and FC HEMI 6.4? The HEMIs sound really nice for being pushrods, so they have to have different firing order than the GMs. But curious what the Coyote is. There're probably just 2 different firing orders in this EPA times.

1-5-4-8-6-3-7-2 ~ 5.0 coyote
1-5-4-8-6-3-7-2 ~ Ford flathead V-8
Cylinder # (both coyote & flathead)
~ Pass side from front 1-2-3-4
~ Driver side from front 5-6-7-8

So if you ever heard a Ardun Flathead at full boogy, that's exactly what a coyote will sound like.

You have the driver/passenger sides swapped.

Modern hemi's use a more traditional V8 firing order 1-8-4-3-6-5-7-2. Old small block and big block chevies use that order, as do all mopar V8's from the old LA series small blocks, to the 426 hemi

Thanks guys. The Coyote sounds nicer, but the Hemi sounds similar IMO. That's crazy how that can be with such different firing order. And how the Hemi and LS/LT GM engines sound so different with the same firing order, and very similar exhaust systems. Interesting. Thank you again.

The coyote sound (vs others) is firing order, header design mostly. Also being 4V per cylinder changes it vs. other American V8s.
I was thinking the multi-cam and 4 valves per cylinder were a factor. However the early 2000 Cobras and Mach 1’s were multi cam/valve and smaller displacement, yet they had a deeper exhaust note.
