Due the the way the exhaust pulses fire, a V6 is NEVER going to have an "old school muscle car sound", only a V8 can make that sound.
The V6 has an exhaust pulse every 60 degrees of rotation, while a V8 has the pulses every 45 degrees, which is what gives it that choppy sound.
A V8 sounds like a RRRRaaaapppp, while a V6 sounds like Blaaaahhhhh. (Best way I can describe it without sound clips!!)
You have to be satisfied with only getting a deeper tone than you have, and putting on a system with that big suitcase muffler isn't going to get you anywhere near what you want. Try looking around for a Cat Back system like DynoMax, FlowMaster, Pipes, etc.
Love the sound description! :bigthumb:
However, it's a bit more than you stated. The tone comes from the frequency (rate of the pulses per second rather than pulses per revolution) and the amplitude comes from the amount of volume being pushed in each pulse (much more important for a deep sound) in the exhaust tube.
When at idle, the rate is determined by the number of cylinders (since idle speed is generally the same for a V6 and a V8, but at higher RPM it's about pulses per second. A V6 at 2500 RPM can sound exactly like a V8 at 2000 RPM IF
the pulse volume and exhaust tube diameter are identical.
In other words a 8L V6 with a 3" exhaust will have the same tone at 2500 RPM that a 6L V8 with the same exhaust does at 2000 RPM.
The V6 pushes 0.6L per pulse. The 5.7L V8 pushes 0.71L per pulse, the 6.1L pushes 0.76L per pulse and the 6.4L pushes 0.8L per pulse. This is where the diameter of the tube comes into play to change the tone of the pulse.
Think of the exhaust as a musical wind instrument....like a Tuba vs a French horn vs. a Trumpet.
It's about frequency, amplitude, tube (diameter and length) and modulation. Frequency is determined by the engine cylinders and RPM, amplitude is determined by the pulse volume, tube geometry is just that, and modulation is about the mufflers and resonators.
