Max-Flow Up-pipes are a good replacement if your stock up-pipes have blown out or you are just looking to add a little power.  With 53% greater flow over the stock GM Up-pipes you will notice a gain in power and reduced back pressure.  Constructed of heavy duty 304 Stainless Steel this set of up-pipes will not blow out like the stock bellows or even other aftermarket up-pipes.  The Bellows use an extremely strong fish scale type round welding around the ring to prevent any damage to the bellow outlasting the competition.  These Up-pipes include high quality gaskets for both sides.  The Full Flow drivers side manifold is a must have upgrade for any Duramax owner. The factory driver side manifold is very restrictive due to the steering column relief. The Full Flow manifold does not have any restrictions so your motor will breath easier which helps turbo spool up and reduces EGT temps. 1/8" NPT bung is pre threaded so connecting an EGT or Drive pressure gauge is easy.

Quality pieces from Dmax Store. These bolted right up, I did have to modify the factory heat shield to fit the new manifold, but that is expected since the manifold is different that the stock LBZ. This setup along with a 3" PPE downpipe and 4" exhaust (no muffler) really deepened up the tone and is surprisingly quiet. My turbo spools much quicker now (64MM) but I didn't notice much change in EGT. I am happy with the purchase.
