Sound for 328

well, you get a 355 if you want its sound.

 

I am not a big fan of any of the aftermarket systems and any of the good ones are expensive. Considering the fact that it really cannot be seen I think a good exhaust shop that make really good custom systems could do better for far less I would go that way. If they weld in flanges for a muffler you could try several and find the sound you want and still be ahead.

 

A 328 with a stock muffler still sounds pretty impressive when you wind it up. No, not like the 355, but still rather nice without being overly harsh on the ears. Maybe I'm just easily impressed.

As I've said to others, I actually took the Tubi muffler off my car and replaced it with a stock can and couldn't be happier - still have the Tubi adorning my garage wall.

Brian is probably right: A good exhaust shop is probably the most economical way to go, though you'll likely have to iterate different setups. Did this on my ol' autocross car.

OR you could leave the 328 as is and enjoy it for what it is. Besides, your ears will thank you in the long run.

 

I'm with you.
My driving gets enough attention, I don't need to be making a lot of noise too. When I had loud cars my driving record read like the vehicle code. With quiet cars I have not had a ticket in a lot of years and I don't drive any different.

 

One of the reasons 355's and 360'second sound so crisp is because of the engine itself. Having 5 valves/cylinder is a game changer for these blocks.
There isn't a lot more you can do to get that "wookie in a coffee can" sound. If there was, it would be a sticky thread already.

 

Wookie in a coffee can? That is priceless!

All you have to do is listen to the rally 308s that basically had nothing, or what amounted to a short cherry bomb for each bank, and you would know very well that Wookies once roamed the forests of Europe.

 

You could try the Borla or Capristro but I heard the Capristro is similar to Tubi, except at low rpm.

Anybody knows how the Larini sounds on a 328 ?

the stock exhaust is dead at low rpm or when revved, it sounds good when driving exceeding 4000 rpm though..

 

I had a Bartoli on my 328 GTB and the sound was excellent at low RPM and fantastic at top end, with a great output too.

The PD Gough/ Nuvolari muffler my car came fitted with is in my shed and stock one fitted. I greatly prefer it. I have never really understood the loud exhaust thing, its like going around shouting.
The sound doesnt get any more pleasant when its loud and simply making it louder will not come close to that of, for example, a 430 Scud which is sublime even when its idling.

 

I like the sound of the actual machine, meaning the engine itself, too much exhaust drowns it out.
I once made the mistake of fitting a 'sports' exhaust to my Countach, it sounded great when you started it up and on idle, but once you wound it up between 3000- 7000rpm all you could hear was exhaust and none of that lovely mechanical meshing of the engine itself.
Whilst we are on the subject, does anyone have a cutaway of an EU QV exhaust can, I just wanted to see how it was 'plumbed' inside the can. Cheers, Bell

 

Agree with your thought about the "mechanical" side of the acoustics -- I've called a stock US TR "a glorious sewing machine"

However, I think that you guys are ignoring in this discussion how the intake side can be a huge influence -- i.e., a K-Jet 308/328 (with a single throttle plate) is never going to sounds as yummy as a carb 308 (with eight individual throttle plates).

Here's a partial cutaway drawing of a 308QV euro silencer/muffler 118353:

And here's an actual opened-up 328 euro silencer/muffler that another FChatter posted (and my guess would be the 308QV euro is the same/similar construction):

I have a Larini on mine and I think it sounds good at higher RPM's. It is very loud compared to OEM and the resonance can be annoying at cruising speeds.

It was expensive and in retrospect I probably should have left the original muffler (minus the cat) in place.

 

Thanks John !

cheers

I have a new Nouvalari 328 exhaust that I am no longer going to use for my project. I'll sell cheap if someone is interested. It has non-stock tips……stock looking tips could be welded on. Shoot me a PM if anyone is interested.

 

Paul Newman has both my 308 and TR. one item I requested Paul to try to make 'better' was the exhaust sound of the TR. The carb 308 sounds so much better at most revs. It is only when you wind up the TR that it sounds somewhat okay, but On its own, even with 4 less cylinders, the 308 sounds much better. The only sound better than the carb 308, in my opinion, is the 12 cylinder e-type.....my kids would say they could hear me miles away with the warbling sound and they would know which curve I was in on the way home with the popping sounds.

 

That's also what I have heard from different owners who had fitted their cars with one. And even louder, with even more resonance when the whole exhaust line has been fitted (headers, intermediary pipes, and exhaust). I am of course speaking about "euro" cars here so no catalytic converter or "test pipe" in question.

I could have been interested in one because I liked the look of the welds, the small exhaust box, etc, which seem to be high quality work, but I am not interested in the car making MORE noise, only a more musical note.

The rear header on my GTB looks rather "somewhat tired", and when I shall have to change it, I'll probably give a thought to a full Tubi line (with the "normal" exhaust, not the "loud").

Yes Steve: I did post that pic a few years ago, and yes the QV exhaust is identical.
Note that of "Euro" cars, German and Swiss 328s (the first Swiss cars without the catalytic converter) have a silencer with slightly different "innards" to satisfy a more stringent noise legislation, so it sounds slightly more muted.
Standard "Euro" QVs use 118156, Swiss QVs (non-cat) use 120640
Standard "Euro" 328 use 127942/1; German "Euro" 328 use 129131; Swiss "Euro" 328s (non cat until mid 1987) use 129407.

Hi Steve, thanks for posting that picture and diagram that's very useful. I did wonder if the gases between A and B cylinder banks were mixed in the can. What happens if you don't mix them and put separate silencers on each bank without mixing the gases? Does it sound odd? Cheers Bell

 

It is easy to see that the silencer/exhaust box mixes the gases from the front and the rear banks even without opening it, as one side of the exhaust box usually discharge more gases than the other, at least at idle: I don't recall if it is the two right pipes or the two left.
On your question, I defer to the engine technicians, but my answer would be that it should be perfectly feasible for a flat crank 90° V8 as this one, because on principle a flat crank 90° V8 functions exactly as two independant in-line four cylinders paired only by the crank.

The Larini is a beautiful piece. It's easy to see why they are so expensive.

I've never ran mine with the cat installed. I wonder if that would tame the sound a little bit.

 

Hi nerofer, yes it should run fine as 2 separate systems but it is an X flow engine and so would the siphoning of gasses be effected adversely by not mixing across the banks? The Countach standard exhaust mixes the gasses in the can like the Ferrari, but the sports exhaust doesn't.
Question 1. Has anybody ever dynoed a standard exhaust mixed in the can ie factory standard vs a non mixed exhaust?
Question 2. Does a non can mixed system ie separate exhausts for bank A and B just sound awful?
Cheers Bell.

 

I have a Larini with the cat. It is louder than stock, but not much louder at idle. Sounds nice when running up thru the gears. It does drone a little at cruising speeds, again not horribly so. I kept my stock muffler, so it's an easy switch, but I'm going to keep the Larini on there for the near future. I was lucky to purchase it from an F Chatter who removed it from his 328.
