Interesting... I recently added a stock LB7 front pipe to my LLY exhaust... no problems... perfect fit.

OneSmokinDuramax,

As you found out it fits great, but you should really consider a cat back system too as the factory 3.5 inch pipes and muffler are very very restrictive too! Call us if you have any questions etc.
