The point that I was trying to make is that while it is possible it isnt practical.  In parts alone you are in the 5-10K range this is before you find someone that could put it together and more importantly STAY together.  That is part of the reason for the very short maintenance intervals ie major service every 25k miles.

Besides if sound is your motivation, save yourself some agony, buy the real thing.

People get so caught up in trying to make the replicas "EXACT" why, that defeats the purpose, especially when they follow up these expectations with questions like.... can you send a .wav of the car engine (that no one else that they know of has heard) or pics of details that they cannot reproduce cost effectively.

So I guess the message is....

Build it first, then add the bells and whistles


my 2 cents

I totally disagree with this. For some of us buying the real thing isn't an option, but that will never stop us from longing for one. I'm currently awaiting the completion of the AD-LP640 kit. This kit is promised to be an exact replica in every way. I'm not one of thoughs guys that plans to build a kit and then present it as a kit I just built. This will forever remain my secret, or at least until it's time to sell it. So for me and probably a lot of others' that are building or planning to build, the sound of the finished car is just as important as the look. And as the saying goes "you never get a second chance at a first impression." That said, to build it first, and then add the bells and whistles would be a dead give away. These kits cost too much money and take up too much time just to fail at what you set out to do in first place, "have everyone believe that your cousin in the Air Force stationed in Italy got you an incredible deal on this Murci LP 640."  Grin

I believe the best thing to do would be to check ebay for the OEM and then make them fit into the fiero.

You know, I have thought about this for months.  I was thinking along the lines of "tuning" the exhaust pipe like you tune a horn (trumpet, etc.)  At low rpms it wouldn't have enough force to make any distinguishing sound, but at high rpm if you could generate enough flow...you just might be able to hit that Italian note, or something close. Undecided

There isn't any solution for the sound. It is in the mechanical design of the engine. maybe you could download something for an iPod that would work through your headphones?

Hi Dave

so the good sound of the extreme replica is just a coincidence? because I see his video in youtube, and I really like how it sounds.
http://www.youtube.com/watch?v=OKyxAvOVpuk

My cousin has a 406 coupe, (no 360 replica) and his original peugeot engine with peugeot oem muffler sound like any car, that engine has no titanium parts or high revs. that´s why I´m confused about this.
hear the difference:
http://www.youtube.com/watch?v=pLL149JFqf8&feature=related

Extreme just added the muffler to the exact same car and the sound changed a lot, to match a Ferrari, in my opinion, maybe you have better audition, and that´s why you think different, (the music teacher told me that I have artillery soldier ears!!).
I will try it, and will be able to tell you in December, when I go and pick the 360 muffler I just bought in USA.

what do you think about how extreme resolved it? am I in a complete different situation?

Sorry but if you think anything on a lambo build is or will be a low budget you need to really reconsider your budget.  I am sure a ferrari muffler is not going to be low budget either. I see all these threads regarding trying to replicate the sound of the real thing.  These cars take so much time to build and so much money that I wouldn't worry about such trival items as engine sound.  You will never duplicate the sound of a V12 as mentioned many times before. it is the 12 engine pulses that makes the exotic sound not the muffler. I would be more concerned by getting the entire vehilce mocked up, before I would care about the exhaust note.

When you have to build your exhaust you may find yourself making a selection based on what muffler actually fits the space and not by how it sounds.

Mike

Thanks Mike

I want a closer sound to a Ferrari 8 cyl. that´s why I´m asking about the ferrari muffler in a v6 or v8 engine,
I´m asking this because of the way how extreme resolved this, and got a nice result, he is my idol!!

I made some test like 10 years ago with my shifter go kart, they all sound like Rc cars or planes, so I took one of the mufflers from my gsxr and fitted it to the kart, it sounded really nice when it was in higher revs, not the exact sound of the GSXR bike, but sounded like a sport bike for sure. I´m not expert in engineering or something like that, after testing it, I got a conclusion, that it needed more airflow through it to get the sound, I´m maybe wrong, but got that impression after testing that.

About the price, I just bought one 360 muffler in perfect shape for $200, that fits my budget  Grin, got lucky on this. but since I´m not in a rush to finish it, I have time to research and ask people like you guys here that have the knowledge and more experience than me while building my project.
Maybe it seems rushed to you, but I just want to have the information and the knowledge for the time this issue needs to be resolved, I will have plenty of space for it, i´m not worried about that, I´m more worried about the sound note.

As soon as I got the muffler here I will test it that way, I wanted your oppinion, but I think this topic turned other different way after each post
If you guys have any other feedback on this, please let me know.
I bought the muffler, and I will try it in my Honda Accord, and in a cadillac. but that may happen in december or january, when I travel to US and Canada, and then pick it up and return to Mexico.

Best regards

The 360 replica in the first video sounds good but not exactly ferrari like.
