[mrdodgeram1999]

what happen if we dont delete the DPF???

[Carbonexpress97]

Were u on high idol ? Sounded kinda weird

[pj1091]

that sound ok but did you put a DPF delete kit in casue you can have engine lock out without the DPF

[xxHILLBILLY44xx]

Did that avoid your warranty when you put that on. cuz when i asked GM they said yeah it avoids it.

[VPRAM09]

sounds like total shit get a cummins

[jd9520T]

Hey what size is the tip on that. Sounds great btw

[tractor1123]

what the f##k is that noise

[puckerzzz]

That whistling noise you hear is the Turbo. It's called a Variable Vain Turbo. EFI live tuning could fix that.

[Farout397]

have you had any problems with the straight pipe? and hows your warranty work with no muffler? just curious because i have a 07 lmm.

[626smd]

none at all. My milage has gone up from 14 to just under 21mpgs. No warranty work as of yet. I have almost 18k miles since i did the switch and no proplems or check engine lights. It has paid it self off with just what I save in mileage. and the power is awsome.

[Farout397]

nice! that's awesome. thanks!

[BoeingXtremes]

Are they hard to swap or do you need a car lift??Also what do you do with the sensors??

[BoeingXtremes]

Do you have a dealer that works with you??

[smdpornstar]

what do you mean works with you

[BoeingXtremes]

They let you keep your warranty.

[buntcakemadness]

Do you realize that engines need back pressure to run correctly? retards

[626smd]

i guess you dont have a diesel. The turbo provides the back pressure you idiot.

[buntcakemadness]

sorry man I forgot duramax are turbo diesel. not really into the whole truck thing....

[1dirtybum]

Yeah dude its a diesel i run a 5 inch turbo back straight MUFFLERS SUCK

[BoeingXtremes]

Did that kill your warranty???

[BoeingXtremes]

so what happened to the other stock exhaust pipe the five inch diameter one????

[626smd]

what do you mean, what happen to the other 5in one???

[Abdullah57]

what kind of programmer r u running with no dpf?

[626smd]

efi live 100 horse tow tune very good egt's and very little smoke

[chevyburnout1]

Nice sound. Kinda reminds me of the ol straighpiped 7.3 Powerchokes with the turbo noise, just more badass sounding! lol

[Slackerjr92]

What kind of piping did you use?

[smdpornstar]

its a magnaflow 5in turboback system. Deleted the muffler, cat and DPF. 19mpg now that the dpf is off. All the hangers match up but one. Very nice and inexpensive kit

[s172mch]
