Does this part have the flanges on both ends, so it is a bolt on installation? ( Brian, 03/23/2023 )
Hi Brian, those do have flanges and are a bolt-in application. The gaskets are :

Re: PN W0005092.
Is this the correct converter assembly for LH/RH sides of a 2005 W20 8.1L chassis? (2005 Winnebago Voyage WFF31W, VIN 5B4MP67G653399866)
If yes:
Can you tell me the approximate flange-to-flange length?
Cost per converter assembly?
How long to ship two (2) converter assemblies to CA zip 91701?
Thanks...

The correct catalytic converter for your VIN is W0007169: https://www.ultrarvproducts.com/W0007169-Converter-exh-Asm-Conv-1-Per-Asm

I don't have the length of the converter flange to flange but it is the correct part # per your VIN.

The cost is $1354.16/ea and it would take approx 5 business days to ship to your ZIP.

Yes, that is the correct catalytic converter for both sides on this VIN.
