Ok ya'll. See sig line before you reply . Didn't like the sound of the flow pro muffler so I took it off and straight piped it. The truck is a little bit louder when normal driving, but put the hammer down and I have the most bad *** sounding truck on the planet. The 6.7 has got to be one of the coolest sounding trucks ever. Just sayin............Love the sound.

 

have you heard one without the vgt turbo o ya even better i have twins on order for mine im ready to get that vgt gone

 

i had to get a guy a muffler. it was too much drone for him.

 

Thanks Tony, the muffler stopped the drone. Hate that it quietened it down some but couldnt take the drone.

 

i thought you might chime in.

 

How hard is it to swap the vgt for something like a silverbullet 66..could i just yank a factory 5.9 manifold and bolt it all up?

 

ya im using a 3rd gen manifold on mine for my twins and you will have to plug the coolant line and think you need the 3rd gen elbow also there is a thread on here some where but im fixing to do my twins here in the next couple weeks they are in shipping right now and be here early next week and i will find out what all we need and how hard it is think its going to be a fairly simple job im going to take pitures like they did in the other thread and do the same thing

 

Ive heard a couple with a Silver 66 and think they sound pretty awesome

 

Im not looking for big power making in my truck or to really tear anything up, but i tow alot of heavy loads and really like the exhaust brake. Im thinking about just putting the industrial injection hybrid vgt in there to keep the exhaust brake

 

i have heard the price of them are rediculous
