That was well said. I agree completely

Ok I think I'm starting to understand what you're saying about the exhaust tuning. In the past, I was thinking it was due to the small displacement of the Ferrari V8, or that it had some wacky firing order. When I bought a 96 Taurus SHO a while back, it had a 3.4 liter V8, so that threw my first theory I had about the Ferrari's V8 sound out the window.

I think the sound as stated has nothing to due with the exhaust but the angle of the block the v dub vr6 has a 40 degree block I believe that's why it sounds the way it does the GM 3.8 has a 90 degree block that's why it sounds like ****

The VR-6 is at a 15 degree angle, with staggered cylinders. It's barely a V, and it only has one cylinder head. The top of the block where the head mounts is flat as a board. It also has an interesting firing order.

now thats cool thanks for the info interesting stuff
that must be why they sound the way they do

Even the venerable VW flat 4 will wail like that with a ("Bag O' Snakes") 180deg. tuned exhaust. Compare that with the "Cessna" exhaust sound of a Subaru without the benefit of 180deg. headers.

It really has more to do with the firing impulses. A 4stroke engine only fires 1time for 2rotations of the crank. That's why 60/120deg. tuning works for 6/12cyl engines. The exception being those with unequal firing sequences I.E the GM 90deg V6. The VW VR-6 does a totally different thing by being almost an inline 6 and uses the same firing order.

Actually; You're right about the wacky firing order! Ferrari V8's use a unique flat-plane(180deg)crank and 1-5-3-7-4-8-2-6 firing order. Vs. a conventional V8's(90deg)crank and firing order(s).
