Tell me what removing this ring is suppose to do for performance other than make the old CTD moan?

 

prevents surging at light load situations

 

is that true? About preventing serging

 

yes

 

Dunno...but it gives me another reason to say I did it other then to make it sound good.

 

I helped my buddy get up the nerve to remove his cone of silence tonight. He as a 2003 3500 srw with auto. this is the first thing he has done to the rig since he got it 2 years ago. He has some catching up to do.

 

I made my intake pipe out of 2-4" PVC couplers and a 5" piece of 4" PVC pipe works really good

 

that does work, but the stock pipe is 5.5" across, so you are asking a lot of the rubber to compress to seal against the smaller size... maybe someday check and see if you are getting any dust into the intake from there...
