this is what happened to one that was removed

 

Oh, OK, I wasn't sure if the 5.9's had them or not

Well.... there ya go !! Ya got the green light to straight pipe your 5.9 andkick the cat whileyou're at it

 

Hehe

I think I will stick with the MagnaFlow

 

Something no one has mentioned. You already have a 4" diameter exhaust from the turbo all the way back. You don't need any more, just do a muffler replacement, like mine or if you like magna use theirs, and then you can decide if you want to eliminate the kitty or not. I opted to keep the cat for now. BTW bigger exhaust with no engine mods = loss of low end torque and lower mileage.

 

You are correct. I am looking at just adding the muffler and tip but being new to diesel I'm not sure if there will even be a sound or mileage difference just doing that. What ya all think?

 

STACK IT!!!!!!!!!!!!!!!!

 

My 6.7 smokes like an old lady in a casino.

 

*sigh* do I need to vid my truck smoking

think of what sharx did. . .but a bit darker and lasting longer

 

I just did the muffler, and it is pretty quiet until you put a heavy load on it, then it talks pretty good. I did not notice any loss or gain in mileage with the muffler change.

 

My 6.7L emitted no smoke or soot until it hit about 1,500 miles. Now it does every time I accelerate. If Iset my Edge unit to "3" or higher the smoke billows out like ten old ladies in a casino!
