Do you have a different kit if I have a PTO and bumper winch ?

Willys Jeep Parts Tech:
Sorry, that you will have to modify.

Will this kit also work on the M38 a1 ?

Willys Jeep Parts Tech:
649869K is what you want for the M38A1

Willys Jeep Parts Tech:
No, but we have all the exhaust for your Jeepster available.

Will this exhaust clear a side shift trans.

Willys Jeep Parts Tech:
I think you will have to bend around it a bit.

will this fit a 1968 cj5 with the dauntless v6 engine in it

Willys Jeep Parts Tech:
No, the V6225 is different.


Willys Jeep Parts Tech:
This kit would work - you would just need to extend the long pipe 18"

Will this exhaust fit a 1946 CJ-2A column shift?

Willys Jeep Parts Tech:
Yes, this will as well.

I bought exhaust kit # 641856K , do you recommend painting it, I noticed a little rust forming around the crimped ream of the muffler and it has only been about 150 miles on a new build. If so, what type of paint?

Willys Jeep Parts Tech:
We never paint them but I suppose you could use some high temp engine paint if you wanted. They are plated.

Does this kit come with all the needed exhaust clamps?

Willys Jeep Parts Tech:
The exhaust clamps are different depending on vehicle. They are a separate item.

Hello, I have a cj5 1969 with F4 134. (in France Normandy) My fuel tank is rear on this model. This Kit work for this configuration ( i see another kit for front fuel tank) ? Do you have diagram for installation (my actuel exhaust is complety différent from the original) ? Thanks for yours answers

Willys Jeep Parts Tech:
Depending on where they mounted your rear tank you may have clearance issues.

Do you need to weld these pipes together, or is the overlap and hangers enough?

Willys Jeep Parts Tech:
You could do either. We typically just use the clamp.

hi! what is the weight of the shipping? item+box? i need send it to another country. thanks!

Willys Jeep Parts Tech:
It goes in 2 boxes. They are approx 18 pounds 24x12x8 and the long pipe is 8 pounds 65x8x4

Do you sell the muffler separate for a '57 CJ5?

Willys Jeep Parts Tech:
641878 is the part number.

I got this system from you only to find that I may need to modify it. There is a Bumper Winch connected to a PTO. The PTO drive runs over the cross member at the same spot that the exhaust pipe is designed to go. What is the appropriate fix? Thank you, Marfk

Willys Jeep Parts Tech:
If you have a PTO then they used a different long pipe to accommodate. You'll have to modify the long pipe if you want to keep the PTO off the back of the transfer case. You can call and ask for Mike M. if you have any questions.

Does this fit the FC-150?

Willys Jeep Parts Tech:
It does not, I'm sorry. You will have to get all the pipes made up locally. Thanks!

Does the "complete exhaust system" come with all clamps, hangers, etc.? My CJ 2a 1946 system is missing so I don't know what is needed.

Willys Jeep Parts Tech:
No, I'm sorry they don't but we do sell them separately. We sell a universal set, part number -2A0402 and a more original kit, part number - 641874. Thanks!

What is the recommended modification to allow this system to clear the PTO drive? Do we bend the pipe to go below the frame?

Willys Jeep Parts Tech:
The driveshaft for your PTO will go in same spot. You will have to run the exhaust pipe to the outside of the frame rail to work.

I bought this system from you and find that I have a PTO going to the winch up front is in the way over the first crossmember. What is the fix (other than removing PTO) Thanks

Willys Jeep Parts Tech:
If you have a PTO on there then the stock exhaust system has to be modified to fit for clearance or the PTO removed.

I have a 1968 jeepster commando with a hurricane (4 cylinder -134) and T90 transmission. I'm told this is the original setup. Is this true? I need the complete exhaust system......is the 641856K the correct kit?

Willys Jeep Parts Tech:
Yes, the Jeepster Commando did have that as an option. However you will have to have the exhaust system made there locally for it.

I have a stock CJ2a it needs a new 12 volt starter and this exhaust kit. Do you have the starter for the 134L engine 12 volt and do you combine shipping?

Willys Jeep Parts Tech:
If it is the original starter than the correct 12 volt starters will be: AA4113-12V as an original replacement and A1245-12V as an after market replacement. Both will work. Thanks

I have a 1969 CJ-5 with the 225 Dauntless V-6. Will this exhaust system work on it. I am having a hard time finding a new exhaust system for my Jeep.

Willys Jeep Parts Tech:
The V6 in the Willys used a number of different manifolds so the pipes changed. You will have to make it at a local muffler shop.

I've got a 1960 Jeep Willys FC-150 that was converted to a horrible vertical stack through the truck bed. Would this kit work with my truck to take it back to stock? It's an F-head. Thanks, Brian

Willys Truck:
Really this will only work for the vehicles listed. I would have your FC exhaust made locally at a good muffler shop is your best bet.

will this exhaust work on a cj2a with P.T.O on the rear ?.

Willys Tech:
If you have a pto in the rear then you will have to re-route your exhaust around it.

Hello. I have a 53 cj3b f head is this the kit I need. THANK YOU!!!!!!!

Willys Tech:
Yes, this is the proper kit above.

I have a 46 cj 2a with a rear pto do you have a complete system for this vehicle or will this system fit? Thank you

Willys Tech:
If you are running a PTO then you will have to make your long exhaust pipe there locally.

Will this exhaust system be clear of a foward-running PTO/driveshaft?

Willys Tech:
If you have a PTO the exhaust system is different.

Do i need some seals between the 4 different parts ?

Willys Tech:
No they clamp together like original. This kit does come with the front pipe to manifold gasket.

I am looking for a complete exhaust system for a 1970 CJ 5 with the V6 - 225 engine. Any thoughts?

Willys Tech:
I would have your local muffler shop make this for you.

Does this kit include the Clamp & Hanger kit needed to install ?

Willys Tech:
That is part number: 2A0402

your kit #641856-k do you have the kit for the 1969 v-6

Willys Tech:
This is for 4 cylinder Willys only.
