04 and 06 exhaust?

[Texas Bulldog]

Will my 4" Bullydog Exhaust transfer over from my 04 LLY 3500 LWB SRW CC 4X4 to a GMC of the same design, 06 LWB CC single rear wheel 4X4?

If you are doing full system then yes. If cat back you will liklely need to do some adapting as the 4 bolt flange is no longer used.

Texas Bulldog,

If your 2006 is an LLY it'll bolt right on, if it's an LBZ the cat/front pipe is a different length and uses a butt joint and band clamp to connect the two pipes. You can take any LLY/LB7 complete front pipe back system and it will bolt on an LBZ but the ability to re install the factory cat will not be functional. If you're confused call us we'll be glad to help.
