I'm in love with the bubbly sound that cobras make from the Windsor motor. However, I am not sure as to why they do this?

I have a guess as to why it is. Is it a combination of 1-4? Is there something that is more definitive?

1. Firing order
2. X pipe
3. Mufflers
4. Displacement

 

The firing order is why it sounds mellow and smooth... I think it's the best thing ford could have done with an engine. :0)

 

i also love the bubbly motor...thats why i have a mini version of it, i call it a WOTT sound but bubbly works...mine does it when she idles.i love it

 

its more of a warble or a burble. Not a bubble. lol bubble just sounds ghey. But its because of the cams. The stock grind of the 03/04 DOHC mustangs(Mach's included) sound amazing.
