Headers and sound

[MustangMental]

How does the sound change with catted headers and an aftermarket resonator delete and exhaust compared to catless headers? Also are the horsepower gains the same or different?

From my understanding there is very minimal difference to power or sound but I cannot truly speak to that as I have never done headers of any kind before this car and I went catless

Running E30 kills any smells for me.

Yeah I have heard people say that E85 will actually smell sweet. I live in Canada though so E85 doesn’t exist besides straight E85 in a barrel which for a HPDE car doesn’t make sense for me because it would cost like a grand a weekend in fuel.
