Modern Vespa

So I have these 3 ALLSTATEs. 1-55 2-57. I picked up this new exhaust and thought it was for an Allstate.

Let me explain, I got this widebody book (kinda expensive, could've been done better, bigger pics less ads, etc)

Then I bought this NEW exhaust and seller and I thought it was for one of my Allstates as can be seen in this ALLSTATE book

But when compared to an older exhaust I have it does not match up

And all of my engines are VNA2M. and the cylinders are all the same. Like as described in the Widebody book by Sticky. Which doesn't cover Allstates or earlier 2 port cylinders that have the Intake and Exhaust right next to each other.

The book doesn't cover the earlier 2 port. Any ideas when the change was made. I am thinking 53. Sticky says all 2 ports can be identified by the exhaust coming out the bottom with the curve in the exhaust, but this can't be true.

The new exhaust fits this kind of Cylinder which is from the Earlier Allstate book. Notice the ports are next to each other.

Notice that it is two-transfer-port engines while your new exhaust seems to be for single transfer engine.

Know how to weld and have an angle grinder?

This is real easy- you have bought the wrong parts manual for your bike. The tri-fives are very different from the 100-105 series.

Sticky is 100% correct in respect to the exhaust existing on the bottom for 2-port engines and from the side for 1-port engines. There are also a host of other differences as well, and to the folks that have this knowledge, easy to identify by just looking at the outside of an engine.

Yes I have Miller Synchrowave 250 TIG and Millermatic 250 MIG - that is the plan, cut and patch then weld a bend. I've built some custome exhaus ton cars, so this shouldn't be a big deal, just takes time.

Thanks for the comments. I was given the parts manual w the tri fives, I don't think the seller realized it wasn't correct. I didn't purchase it.

I wonder why he didn't include information on the earlier engines as they are also included in "Wideframe" models.

albeit that would get confusing with the VNA2M stamped engines that were installed in the largeframe VNA bikes. . .

Why not return it and buy the correct one??

What's wrong with the original exhaust?

So you are looking for another one like your original, and you have THREE motors to equip? I think I have one like that i could let go fairly cheep...

Yes, plese send me a DM. I appreciate it.

Because the seller has supplied me with a lot of parts I need and I told him I would work with it, he's a good guy and just didn't realize it was for earlier models only.

I need 3, so was trying to purchase more

I'm also looking for an Allstate cowl door if anyone has one to sell. Thanks
