ANSA exhaust system for 3500GT Vig???

Ciao Tutti,

Does anyone has by any chance bought this exhaust system and installed it ???
ANSA for some time used to supply Maserati for its exhaust systems... Am just looking for some precise measurments info...

Molto Grazie

I purchase and installed the rear Ansa muffler for my Vignale Spyder 20 years ago. I had to modify the exhaust tips as they were too wide. As you know there are at least four different exhaust configerations for the Vignale Spyder. I believe this rear muffler was gernic and was designed to fit 3500 coupes, Spyders and early Sebrings.

 

I agree that its a kind of generic made, and agree that the rear tips are not the ones I am looking for, too wide apart and diameter of pipes are too big... I just want to figure out how accurate these are built versus the original ones, especially the diameter size of the pipes running from the headers to the mid section, and then the diameter of pipes of the mid section to rear muffler... Hard to find the info...

quicksilver of the UK shows one for the Vignale and late 3500GT

I have had great experience with them.
If there was someone who has an original system for measurements that would of course be the best.

Yes, quicksilver also builds a quality generic model, but have heard they are quite a pain to fit in either a 3500GT or vignale... And also not built to 100% original specs...
Luckily I am in possession of the original tec designs of the mufflers system from Maserati Modena for 3500GT Vignale and I can affirm that none of the generic ones, quicksilver, ANSA, come even close to originals.... It is my endeavour to built a system totally to 100% original specs, which is rare if not none existant nowadays... No one really cares about originality, a shame since it is like erasing history... Not the case for me as I am rebuilding lost history...

Would you by any chance know the four different exhaust configurations for the Vignale Spyder by years???... I found that quite difficult to establish since back in time, Maserati would fit an exhaust based on what parts were available in stock and this would change all the time, thus super difficult to figure out what configuration is correct to what specific Vignale.... a pain...

Ciao

I do not know that Maserati was consistant in making the exhaust by years. I agree with you comment that they used what was on the shelf when the car was built. Part of the problem is that cars were not finished sequencely for example car 981 date of production was 10/Nov/1960 and there were 20 -25 cars with later serial numbers that were built befor that date.
When I replaced the muffler on my car # 1119 30 years ago I was fairly sure it had the original muffler on it at that time, so I modifyed the Ansa muffler to replicate the original.

 

Interesting...

Great decision you took about replicating the original, I am working on that, not easy but really worth the trouble IMO...

 

Gene, did you ever pick up my original system, from the exhaust shop, to copy?

 

I have an original rear system and an NOS original "aftermarket" ANSA rear system.

If you want photos or measurements let me know.


Ciao and best!

Hi Trev,

That would be of great help, here's please what I need:

1) lenght of rear ANSA system, just the muffler

2) Photos and lenght of the 2 small central mufflers

3) If you can, the measurment of the OD of the pipes that run from the headers to the central exhaust system (the one that has the 2 small mufflers)

Many Thanks for your precious help

Yes Mark I did pick up your old exhaust system. It does look original and has the correct center mufflers which is what I needed to get correct measurements. Thanks again for saving this as the old correct systems are becoming more rare. It looks like the down pipes have been replaced since they do not have the flex pipe welded in, but they is enough of the original pipes left that I can get the measurements. The rear muffler for this system was not the cross muffler that Carlo needs the measurement and in this case did not come with the system.

 

Gene, I'm glad you got the old system. The down pipes looked terrible....looks like someone took it to Midas for some custom work. I wish that the rear muffler on my Quicksilver system was tucked up and out of view like the original one was.

 

Carlo,

I'll get you the measurments of what I have as soon as I can. Maybe today or this weekend.

Ciao and best!

Per your request attached is a drawing of the center mufflers and the pipes.
The mufflers are 40cm long 15.5cm wide and 8.7cm thick. The header pipes are 5cm as are the exhaust pipes. Note the center conection pipe is slightly eliptical. I hope Trev gets the same or similar demensions

Many Thanks eogorman for your fast response for this precious precious info, this is very helpful... This is original...

Just wondering how the connection is made if the OD of the header pipes (to be 100% clear;
header pipe = the pipe with a flex section running from the headers to beginning of the central mufflers) are 5cm OD and so are the inlets of the central mufflers, any thoughts??

Interestingly my header flex pipe has a OD of 4.5cm which must not be original, therefore I must replace it as well...

Hereunder marked with a red cross the header flex pipe which I am talking about...

Also second picture measurements of the ANSA system from a ANSA dealer, except for the rear muffler exhaust pipes, measurments seem original...

There are many sections of the header pipes that have been replaced so i can not answer you question. The header pipes on my car measure 46mm and would slip inside the 50 mm pipes. I am not sure my header pipes are original. Maybe when Trev responds we will get the answer.

 

Yes, what a puzzle... Maybe the 45-46mm is original after all...?

Here's the measurments on my side, as you can see the beginning of the header measures 50mm, the flex section as well 50mm, but after the flex section, the pipe is reduced to 45-46mm, I strongly suspect this part to have been added and not to be original, someone must have welded the last part on... The weld seems too nice for it to have been made in the 60s...

Eugene, wonderful work on the layout for the 3500 GT exhaust.

My original system is the same as the one on your layout.



Carlo,

Per your request, here is all the information I can give you from what I have. I believe my front section from the exhaust header to the muffler has been replaced. The "center" sections, with mufflers are original. And the rear muffler LOA is from the NOS ANSA system.



1) Center mufflers are 40cm. each muffler, LOA. As per Eugene's layout.

2) Rear muffler, LOA is 74.1363cm. (single muffler) not including any pipes


I hope this is helpful. Sorry about the plastic on the NOS ANSA section, I didn't want to unwrap the original plastic.

Let me know if you need anything else, but it looks like Eugene's efforts got you most of what you needed.

Good job Gents!!


Ciao and best!

Many Thanks Trev, this is very helpful and getting me closer to my goal...

Just needed to ask you if your ANSA rear muffler has a flat surface (as mine) or has it grooves that go in or out as seen on the hereunder ANSA's photo description, I cannot tell because of the plastic wrap???

Many Thanks
Ciao

Hi Carlo,

My NOS ANSA does not have grooves, and or ridges. It is flat. Apparently, they changed the design after the original issue in the early 60's. ???

Let me know if you need more help.
