| Quiet 4" turbo back exhaust
Can anyone tell me which of the 4" turbo back systems will produce the LEAST amount of noise. I want the advantages of the 4" but not the loud rumble.. Any suggestions? |

| Just about all of them will be the same. My 5" with a muffler isan't that loud at all. The only time you can hear it is if you are getting after it pretty hard. Even a straight piped duramax isan't that loud inside the cab.

| I agree with Big Red, I have not heard a load Duramax around here. Mine has a little rumble but it is really not that loud.

| Will I need an EGR false code eliminator or will the PPE Economy take care of that?
Also, if I get a code and clear it with the PPE, will it reappear or is it gone forever? | |

| I have heard of an exhaust change setting a code but mine has not. I hear it only happens with some. I guess it senses the backpressure drop off and sets a code.

| What model truck do you have? If you get the code the PPE will reset it, but it can come back. It will not affect the performance at all. Mine gets the code but no SES light. I would just wait and see if you get the light and then go from there.

| If you want quiet get the diamond eye turbo back system with the quiet tone front pipe. With the quiet tone front pipe and a muffler they are pretty quiet!!
