No need to delete emissions to make power!
Many people looking to make more power with a 2011 - 2016 LML Duramax think an aftermarket exhaust is required to make power. This is simply not true! Countless people reach over 500 RWHP with just the LML SPADE and a lift pump.
Above you can see the dyno graph from our DPF ON sled pull truck. Named #DTCleanSweep because this truck has "swept away" plenty of deleted trucks on the sled pull track. It sounds quiet, it runs clean, and it kicks some ass! This 2012 Duramax makes great power with the emissions equipment still working. While this truck has a few more upgrades than your normal street truck, it does definitely proves you can make power with the stock exhaust.
Keep in mind this truck came to us deleted, and was returned to stock. We had a chance to test it with both setups. Truth be told, the deleted version made less than 5% more power. Not enough to notice from the driver seat and obviously not enough to cost us anything at the track.
