I'm confused as hell now. Are you saying that the PHYSICAL cylinders fire in the same order yet have different #s on them, or that the #s are the same 18436572 but are #d different in the block.

 

YES

 

I don't think any of you hit the nail on the head here. Have you ever looked to see what the diameter of the pipes are on the Mustangs. They are 2" which with a smaller diameter pipe it speeds the velocity of the exhaust and therefore it sounds better. Not to mention I saw a show on TV a couple of years ago with an engineer from Ford saying why they do this. They engineer the cars to have that sound to help sell them.

 

Yes to which question I asked, why are you yelling?

 

i have a theory on why the stangs and camaros have a better exhaust sound than the vette.

ill start by asking a few questions.

1. what does the exhaust on a stang and camaro have that vettes dont have?
2. why does a trumpet sound richer than a cornet?
3. why does it sound throatier humming through a paper towel core compared to a toilet paper core?

answer: the tube//bell/pipe is longer

ever noticed how short our exhaust pipe is after the muffler? it is only about 8 inches long. now look at the exhaust pipe after the mufflers for a stang or camaro. much longer than a vette. this gives it an added vibration, kinda like a tuning fork. the air/exhaust passes through the longer exhaust pipe much like a pipe organ. ever notice how the longer/bigger pipes on a pipe organ produces the deeper/lower sounds?

in order for us vette guys to achieve similar sounds from our exhaust, we need to lenghthen the exhaust pipe after our mufflers. we cant do this with current vette mufflers since our cars would look funny with 2' of exhaust pipe sticking out the back. the only way to achieve this is to relocate the muffler. my guess is, we need about 30" of straight pipe after our mufflers.

this also partially explains why the elim pipes sounds better, but the flaw with elims are, they bend. the bend alters the vibration in the pipe and changes the pitch in the exhaust note again. the straighter and longer we can make the exhaust, my guess is the better the exhaust note will be.

just my $.02

 

I'd have to agree with you... I won't own a Mustang because I used to work on my friend's sisters GT and my dad's F-100... I hated the way everything was laid out on a Ford engine, but that's another rant... :D

I've heard quite a few exhausts, but IMO I have not heard one that sounded more "perfect" than a Mustang's exhaust, both stock and aftermarket... Stock for stock they have a better sounds, and even aftermarket vs aftermarket (GM Flowmaster vs Ford Flowmaster systems) the Ford's always sounds better to me...

Although I love their sound it's not enough to get me to swing over... They can have that little win... I'll take my Vettes and F-Bodies any day...

 

Well.. to even things out.. at our marina I've listened to many different engines in our shop and most have had nearly the same exhaust (water jacketed, short runners, though the transom... basically open exhaust) and there is a distinct sound difference between a Ford and a Chevy. Doesn't matter if it's a big or small block.

 

Theyre loud because Ford designed them to be that way.

 

The Ford and Chevy in question fire in the same physical order...meaning they start with the DS front, PS rear, PS second from front, DS second from front...etc.

 

My '87 with a CompCam #501-8 camshaft running through straight pipes after the main cat will outrun a Mustang GT SVO (friend has one) and sounds better too. Maybe exhaust sound is in the EAR of the beholder.

FWIW,
BIG JIM

 

:iagree:

 

The only Mustang that i have heard that i fell in love with the exhaust was the 2000 Boss Mustang ...it came stock with side pipes..it was also a concept car not all that available. :cool: :D

 

The only Mustang I've heard or seen that I would like to own is a lat 80s Saleen with a cam. A kid in the area had one with the Stage III cam and head work. That one sounded sweet.

The Chevy 350s sound deeper because of the bigger displacement. The Rustangs can go with louder with megaphones very easily, but deeper they can't get. But nothing matches a mid-year 427 with the high compression engine and side pipes.


A new Cobra convert just went by my house getting on it. Loud yes, deep no.

I wonder if it has something to do with the resonator. I put the exact same mufflers on my 96 that I had on my mustang, and it just doesn't sound the same. It pretty much goes silent above 1500 rpm, and the only thing I can hear at full throttle is the engine accessories. I plan on cutting that sucker out this week.

And there's not a damn thing wrong with admiring mustangs, people. They're good cars, and a lot of us started out hot rodding these things. Just because we've moved up doesn't mean we have to ignore what got us here.

 

I must being the minority here, because I think v8 flowmastered mustang sounds like poopie and no I am not a mustang hater either (I came really close tor buying one myself and my frineds had a few). The is nothing beefy about a resonating mustang with an airy sounding exhaust. IMO they sound good under WOT, but not in everyday driving. The reason they resonate so much is rear crossover is in the wrong place.

 

Ahh, the sweet sound of ALL BARK AND NO BITE!!! :yesnod:

 

no
their cylanders are just numbered
15
26
37
48

vs
12

78

its due maily to thier H pipe

 

actually-
the viper fires like 2 indipendant 5cyl motors
thats why it sounds like rats butt :rofl: :lolg:

 

it is the length of the pipe after the mufflers, and the motor itself.

 

no, technically, it's:

51
62
73
84

different #1 location as compared to sbc. the firing order is still the same, though.

also, note that for a 90 degree crank, there's only two possible firing orders. the other possibility is what ford used in the pre '81 302. later 302s (and modulars) use the SBC/351W firing order.
