Can you give me dimensions? inlet OD, outlet OD, length and diameter of muffler. Thanks

Willys Jeep Parts Tech:
Length: 18", Diameter: 6 3/4", Port 1: 1 1/2", Port 2: 1 5/8"

What should be the correct clamp?

Willys Jeep Parts Tech:
Both clamp kits we sell will work for this exhaust. See parts 2A0402 & 641874. Thanks

Hello, Just purchased a 1961 FC-150 to restore. Would this be the appropriate muffler?

Willys Jeep Parts Tech:
This may work, but I dont carry the exact muffler for the FC-150.

I have a 1970 CJ 5 with the 6-225 dauntless. Do you have the correct muffler for my application? All I see you have for the year and CJ 5 is for the 4 cyl. application.

Willys Jeep Parts Tech:
I'm sorry, this will not fit the CJ-5 with a V6. To get the V6 exhaust parts, try a local Midas shop. They should be able to make it up for you. Thanks!

I have a 46 CJ2A. I don't see any muffler hanging brackets or for tailpipe? Do you have?

Willys Tech:
We have two kits available part numbers: 2A0402 or 641874

What are the inlet and outlet pipe sizes. I think my system may have been changed from standard sizes.

Willys Tech:
They are approx 1-5/8 o.d. and 1-3/4 o.d. on opposite ends just like original.

What are the complete dimensions of this muffler

Willys Tech:
The muffler it self is 9.5 and the overall end to end is 18 in lengh.
