no, it would require a different controller. The aurora 5000 really sounds like a jet getting ready to take off. If you were to do a twin set-up it would sound good too. It has been discussed on other forums about trying to take a LLY turbo and put it on the LB7. From what I read, it wouldn't work and from what guys are saying, the fixed vane turbo is less complicated and less things go wrong with them.

Also, the duramax does not have a silencer ring like the cummins does.

If you really want a load whistle just disconnect your exhaust from your down pipe. You will hear nothing but turbo whistle all day from idle to red line.

You may also try putting on an aero Turbine muffler they work awesome and they give alittle more power and mileage.
