Banks Speed Brake

[Alberta Rhino]

Looking for input on the Banks Speed Brake for the Duramax? Does the Banks system as they advertise have more holding power than the Pac Brake ? Either system cost wise comes out to about the same price since I believe you need to purchase at least a 4" exhaust to run the Pac. I have no other mods in place. Which would be the best bang for the buck. Thanks

If i remember right, the speed brake uses your factory VGT turbo as an exhaust brake. The pac brake is a actual exhast brake. I would think both would work well. If your towing big loads you will want the 4 inch exhast anyhow. I can tune your ECM to use your VGT turbo as an exhaust brake, plus side to that is I can throw in a bit more power, and kill your EGR.
