I can't find 1 reason why people are going to go to a DPF BACK exhuast. (Other than for looks obviously). It doesn't even change the "Tone" as stated.

What I can not understand is how NO ONE has been able to create a DPF system, that will allow allow more aggressive sound (if one wanted too) and still be capable of affiliate the emission compliancy.

I did hear however, their was a MAJOR breakthrough with SPEED OF AIR TECHNOLOGIES. Company that has made these particular pistons to help reduce drastically the amount of emissions that are being put out by so called (diesel) trucks. That is more reliable then the DPF system themselves.
