When I barely get on it, my exhaust will flutter (between 1000-1700 rpm's)....any ideas why given the mods in my sig?? And any way to get rid of the fluttering?
Thanks for any help!! I'm new to my Cummins!

 

try to explain the flutter a little more. make sure everything is tight if its more of a rattle

 

If you can post a video of it that way we can help you out better. It is always easier to hear and see something then reading it and trying to figure it out.

 

dalton.lenoir and H.R.D ... If youre just babying the peddle all the way up until it really opens up at 2k rpms, itll make like a shakey fluttering sound (like pulsating). Everything is tightened up in the exhaust system, and it seems to only do it in drive, or reverse, not in neutral.. any ideas?? ill try and get a video up here tomorrow so you can hear it for yourself, thanks guys!

 

mine did the same thing in my 94 and it was because of bad injectors
