What year did dual tail pipes Start

[85GTTops]

personally speaking, I don't think most people even knew there was a difference in horsepower between the manual and AOD cars.

That's certainly true if the people buying the cars only knew how to use an automatic. But one would think most would have noticed right away the differences, including the hefty $545/$700 premium for the transmission along with a night-and-day test drive of both. We're talking a 30% difference in power.

Add the single exhaust hanging out back and it surely paints a picture of a saggy sales situation of early 85 AOD cars, because,

according to ... "Job #1 plus 60 days" (it ended up being Job1 + 90 days)

... it took an additional 30 days to get rid of all the extra stock.

Not sure if we have the sales stats broken down that far yet. It would be interesting to see.

I know in the instance of Tony's old car, the original owner purchased it with an auto so his wife could drive it too. It was fairly stripped down and the original owner paid extra and waited for it as well if I recall correctly.

Sales were very close between the CFI/AOD and 4V/T-5 convertibles. The difference was less than 8% of total 5.0L convertible sales for the model year.

aaron......you see this??

Yes, Do you also Notice the Metal fan??? which would make this a Early 85, also, looking at the valve covers, they may have been added to the car as early 85's had the Metal Valve covers, or am I wrong about this to! I know one original 85 AOD owner who had finned valve covers installed on his 85 AOD coupe after he bought it new from the dealer.

Im just saying, unless you bought the car new, who knows how it actually came, Like my 95 Cobra, I bought it new it only has the CD Radio in it. Everyone who sees it says they all had cd/Tape in them. Mine did not.

Not trying to argue, who knows what people added to these cars after they bought them.

good points, but, most folks that wanted the AOD cars for some reason or another didn't even think about test driving a manual car, so it would have been real hard for them to notice the differences.
for folks that really wanted an automatic car, the new AODs that were introduced in 85 were actually something people looked forward to. I believe they put this same tranny in the turbo thunderbirds. In the case of the original owner for my car, he ordered it in I believe maybe Jan and the car didn't even arrive at the dealership until June. Apparently there was a big backlog on the new and improved AOD trannys and the big luxury cars had first dibs over the Mustang orders. This is all second hand knowledge, but, what I was told. I agree big difference in power relatively speaking, but, for back in the day 180 HP was still pretty good for a very nice driving V8 mustang.

Aaron, the AOD cars had metal fans early and late. I don't know quite when they phased out the alum valve covers for the black ones for the AOD cars. They may have used them for the early and at the beginning of the exhaust conversion but haven't seen enough cars to be definitive on that one.
I know for sure the metal fans were early and late. I had a metal fan on my car...a late car.

The plot thickens. According to the master parts catalog, E55Y headers were used on 1985 convertibles, which were different than the E4ZZ headers found on the coupes and hatchbacks. This was a one year only header set. So the question is, did any 5.0 CFI verts have single exhaust and cast headers in 1985?

It is possible that 5.0L CFI convertibles weren't built until after the improved exhaust was implemented for that engine.

The only Deluxe (Marti) Report that I have seen for an '85 5.0L CFI convertible shows a three month delay between when the car was ordered and when it was "serialized" (assigned a VIN). The day it was "bucked" (bare chassis formed completely) was after the Nov. 19 CFI exhaust change-over.

That makes real sense. I don't see anything in the parts catalogs showing a split in production for 1985 verts, so having their special tubulars ready before production lines up. As mentioned to Ed, there was a split in the RH tubular header production in 1986 mid-year, but that's the only year I see this occurring.

I hope to post a picture of that header soon. Still recovering over here, so I cannot lift anything over 10 lbs.... Maybe I can persuade my wife to open the hood so I can take a pic...

My 85 McLaren is a late version with the tubular headers, 'dual' exhaust, and black valve covers. The drivers exhaust manifold is a different than the normal 4 in to 1 (all four exhaust ports meet at the collector). On mine, #1, #2 & #4 meet at the collector like normal, but #3 comes out and is welded to the side of tube for #1. I have seen this same manifold on a few other cars. Maybe this is the other part number.... I know there was a discussion a few years back about the various tubular manifolds.

My 85 AOD Twister II has the cast iron man. and had single exhaust that is missing, and I've been trying to find a correct taillpipe with no luck at all, If anyone has a correct new or used taillpipe I'm needing one!!

The oem had resonators in them similar to Hedman Hedders 17106

My Mustang and 85 LX had these dual tips.

This is an oem stainless pipe for an SVO bought at dealer back in the 80's.
The resonator tips rusted off long ago.

The date on tjgstang's Twister II door tag should be 10/84.

Thanks for the info, what a deal I was having real hell of a time trying to find this you hook me up, Thanks again!!

[gr79]

The assy i bought back on 6/1/85 was going obsolete and got a deal on it.
Bought it over the counter at Ed Schmid Ford, Ferndale, MI. for 115.15 List 143.89
According to my notebook records the assy P/N was/is E5ZZ 5230 EX
Note the E5ZZ prefix and the EX. Installed to 85.5?

Had to change over from the 79 setup to the later style hangers.
The later style dual tips are shorter than the early style, different hangers.
E3ZZ 5277A BODY SIDE TP HANGER BRACKET, 2 bolts
E3ZZ 5277B TP SIDE HANGER BRACKET, 2 bolts
E3ZZ 5F262A RUBBER DONUT TO CONNECT ABOVE
E2DZ 5277A BODY SIDE HANGER BRACKET FOR MUFFLER
E3DZ 5277A MUFFLER SIDE HANGER BRACKET

muffler, over axle pipe, split dual chromed tip, all welded assy.
The over axle pipe must be of ss as it has not rusted out. Bracket is fine too.

The chromed tips were welded on to this pipe.
Rusted out on both the assys i had, the factory one and the SVO one.

The end of the tips are not straight 90° cut.
Close as i can measure cut close to 11° or 79° depending on which way its looked at.

My GT has a build date of Sept 1984 and has the correct 85 dual pipes, my friend has a Sept build date 85 LX 5.0 and it has the 84 style tail pipes. Just facts..

Is yours carb/stick car or injected/auto car?

Yeah, that matters, because we are NOT talking about exhaust on the 4V/T-5 models.
