New 8 Lug magazine DPF-LESS Exhaust system
Look at the new issue, Even though it's on a DMAX, there's hope. New exhaust system, turbo back, no DPF!!! Pretty cool for OFFROAD trucks only

From reading the Ford and D-max forums it seems that they are not having the clogged dpf's or the reduced hp after removing the dpf. Not sure how but a D-max friend of mine mentioned that the tuner software for the Chevy's is more sophisticated and is able to ignore the sensors. Something to do with a program called something "live".

Yep, it's RBP. They are plugging all the sensors right back into the exhaust stream. I wonder what would happen if the computer decided to dump some diesel into the exhaust and it was straitpiped. That might be pretty cool if it would ignite, put a switch on it. Instead of smoking people out, you could barbecue them!

Instument guy at work got rid of his DPF on his 6.7.....he measured the clean DPF and there was 3psi drop!!!!!, so he wired in a resister simulating the 3psi drop, so he always has a clean dpf!!!

Measuring the kind of flow these engines put out is not a trivial task. How was the 3 psi drop measured? That seems way too high. If all you need is a 10 cent resistor to simulate the voltage difference that is awesome. According to what I have read there are 3 oxygen sensors and 3 egt sensors in the system. Seems there is a lot going on beyond the pressure sensors.

there was a total of 5 PSIG drop accross the whole system, 3 being in the DPF the remaining 2 accross 2 catalysts and a muffler.
I will talk to him at work and find out exactly what went into this and see if he will hook me up with a drawing.
