Gallardo exhaust
3 doors down from where I live is a 2009 Gallardo (blue). If it has a V10, the Viper has a V10 and our sharks have a big V8, how come the Gallardo sounds so different (high pitch) when on the run? I can hear it accelerate all the way on to the highway ramp about 1 1/2 miles away.

These scale engines each have their representative sound types:
First, a V-8:

Then a V-12:

Then a R-14:

The diameter of the exhaust pipes and the way they merge together has a huge affect on the sound. Your 928 is rumbly because of the dual exhaust. Mine has a Y pipe and also is fairly high pitched.

I know I'll get boo'ed for this comment but I prefer the exhaust noise from my Spyder with sport exhaust much more than the 928's noises. It sounds incredible but not overbearing. I've found that with the 928 the nice sounding exhausts are often overbearing which is one of the reasons I never modified my GT.

The Gallaro V-10 is a 72 degree V which with five crank throws results in an even firing order. So you are hearing two five cylinder "engines". The Ferrari V-8 sounds like a "Ferrari" because although a 90 Degree V-8 it uses a flat crankshaft and runs as two four cylinder engines. Most V-8s including 928s are not even firing they must bang off two cylinders on one bank one after the other.....which with dual exhaust is the hotrod V-8 sound, the burble. As noted if you run your odd fire V-8 into a loud Single exhaust or use a couple Y pipes it smooths out the sound giving a higher RPM sound. The V-10 Viper using a 90 degree V also has an ODD exhaust note due to the firing being uneven. The classic Harley sound is becuse it is a V twin with one crank journal and fires Bang bang then has a long pause as the crank goesthe rest of the way around and bang bang. So no matter what you do to the exhaust it is largely the spacing of the bangs that determines the overall note. The Gallaro does have an active exhaust flap which opens up more when you wish to make noise.....Short answer is a 6,500 Rpm V-8 is never going to sound like a V-10 or V-12 or a Harley You can however easily make it sound like a Mustang or Camero......
The more cylinders you have the more bangs per minute at the same RPM....4 cycle fires the cylinder every other RPM. So the Harley bangs 3,000 times @3,000 RPM, V-8 bangs 12,000 times @ 3,000 Rpm, V-10 is @15,000 times.....so no way to make 12,000 bangs sound like 15,000 or 3,000 ! now a 12 cyliner @ 3,000 RPM gets you a magical 18,000 pulses per minute.

your GT was modified at the factory with the smaller resonators and the smaller rear pumpkin with dual tips,
thats why the GT exhaust is a better sounding unit than the S4

The redline is 8,100-8,500 as well so it doesn't just SOUND high RPM it is ! A V-8 would need to spin 12,000 RPM or so to get close to the sound. It is not going to happen with a 928.

Exhaust note on the Gallardo and Murcielagos are also high pitched due to the piping diameters chosen on these cars. Shockingly, I think the Gallardo's factory piping size is no more than about 2 1/4" for each bank.
Aftermarket mufflers now such as the Capristo, Tubi and Larini have a baffle which tweeks the sound into more high pitch "F1" style tones. See the video below with a Ferrari 355 with a Sound Level 3 (Loudest you can buy) Capristo exhaust. This is also the reason why I am willing to bail on Porsche any day of the week. If you're mechanically savvy and have the factory workshop manual (download it online now), a 355 can be a little more maintenance friendly.

I know my 87 sounded better with the H and a RMB than it does with the X.
The X makes more power so it will stay, but it is louder than with the H, and that is with big resonators.
