🔧 PPE 117000600 Performance Parts and Miscellaneous Accessories Review

I installed this with an upgraded turbo so the cab was already removed which made the installation of my 2012 Duramax easier. Fits well and fits as it should. Pleasant sound of the changing tone of the exhaust. The item appears to be of good quality. Does not come with plugs if you remove sensors during installation so be aware.

Exhaust gas was leaking at the turbine outlet due to the deformation of the sealing surface. Disassembled, cleaned and new clamps fitted, but it didn't help. Then I even tried the exhaust assembly paste, but it still let the exhaust into the passenger compartment when stopping. I finally gave in and reinstalled the stock downpipe and the leak was gone. Many, many hours of wasted time and a large pocket of money. Very disappointing.

High quality product, excellent workmanship, fit, finish and performance! Arrived in perfect condition, very well packaged. Aside from the PPE stainless steel tubing, I've had absolutely no issues with spacing or anything else fitted to my 2013 Silverado LML Duramax cab. Very slight change in tone (slightly rougher), no change in volume, but definitely more turbo can be heard on my emissions compliant truck. Only driven a few hundred kilometers but so far very satisfied.
