Hey Guys,

Does anyone know if a new exhaust side turbo housing is needed in order to clamp on a new 3.5" DP? The DP is a Diamondeye. I bought my truck with a DP already on going to stock exhaust. I have a buddy who wants to make the change also and he says he's read you need a larger diameter housing to make it fit?? I've never heard of this.

Thanks,

Brad

How hard is it to a install a 3.5" compared to a 3"? And is there a power difference?

I bought my truck with the 3.5" (measured it) and I'm not really sure of the make because I can't find anyone who makes a 3.5 online. This 3.5" is a two piece but its been welded together. Whoever installed it pressed the firewall in quite a ways to get it to clear. (I cleaned up the sheetmetal while I had the cab off)

All I know is the 3" I helped my buddy do was a real bear..pretty much no clearance on the OBS.

Not sure about a power difference yet, I'll update once the rest of his pipe is in.
