Due to the recent "which muffler sounds best" threads, I started thinking more specifically about the 4.0 and exhaust sound.
My question is, what makes the 6 banger supercars sound so damn good, and how can you make the 4.0 sound similar?
Mainly for street guys I guess cause I doubt the trail rigs really wanna sound like Porsches.
So what is it? Valve configuration? Valves per cylinder? Tuning/timing? Compression ratio? Genereal head design (size/shape of ports, valves/springs, combustion chamber)? Stroke ratio? Header design? Exhaust design? Or is it all of the above?
I was very please with the way my jeep ended up sounding after my exhaust job. I honestly can hear a hint of "supercar" in the tone. Maybe I'm crazy but nevertheless I think it does.
It always thought that a two valve, pushrod motor could never sound very good unless you added two more cylinders but I have a little bit of hope now. So can anybody offer any insight?
