2008 Exhaust?

husker · 05-10-2010, 02:48 PM

A friend of mine bought a 2008 cummins and he is wanting to put an aftermarket exhaust on it. A few of the exhaust shops around here are saying that it cant be done. Really? Is that true? They told him there is some kind of filter in the down pipe. I know nothing about these truck and I told him I would ask the pro's. Thanks.

You can do a exhaust but you will either need a tuner to disable the codes, CEL and regen from the removal of the exhaust or go old school and use sims to keep it from regen mode.

I'm assuming that will void warranty? What kind of tuner?

Unless his dealer gives it the green light than chances are yes it will void the warranty.

Tuners from H&S Performance or MADS Electronics (Smarty) would do the trick.

Will the exhaust make the truck perform better? Or is it a waste of time. The truck is still stock.

In my own belief, it is the best thing you can do for the truck period. Increased mileage and you reduce the risk of having any of the dreaded emissions related issues on the 6.7....clogged DPF, sooted over turbos, soot or sludge in your engines oil, etc.

It's definately "not" a waste of time.

It want burn as much diesel.But if you do that you need to let it breath too.Like a s&b cold air.James has all of the stuff.

So, is there a way to do this without the warranty being messed with? Or do you just put the stock stuff back on to go in for service? Can they tell if the programmer has been installed?

No what his truck has is a DPF or diesel particulate filter catches all the soot/black smoke then burns it off when it gets full. (in short)

u can take all that crap off, loose warrenty, and get a programmer like said above or do a DPF back exhaust kit which basicly is taking off the muffler or swaping the muffler for a different aftermarket one.

Unless your service dept. is cool with mods being done you're probably going to lose your warranty, (it's worthless anyway). Yes they can tell if a programmer has been installed.

from my experience and from what i have read on here. your going to run into more trouble if you leave that stuff on then if you take it off. I was always throwing codes when i had my exhaust, now that james hooked me up i have not have one bit of trouble
