3" down pipes

[2013blacksho]

Has anyone tried 3" down pipes or do they not fit well.

They do fit, at least on a Gen 4.1, and here are the "adjustments" you may need to make:

Does your SHO have the Performance Package? That makes clearances tighter.

Fit fine no adjustments needed here for noncatted

No non pp and great. Just trying to line up what mods I am going to do in future. Had a dsm back in the day and ran 3" as long I am a hydronic engineer by trade and deal with flow all day everyday and know that while 2.5 may do just fine the less restriction on a pump the better and the turbo being a pump I just want to make sure that the bottle neck is at the inlet and outlet of the turbos not in any piping. I'm going to work on custom intake and hot pipes with a friend that is a master at welding stainless and see what happens. Of course all will be based around a tune for sure.

They quit making them in 3" awhile ago. I originally ordered them but was told that 2.5" would be made from now on because of fitment issues with the larger downpipes

OK cool thanks for the info!

I didn't know you can still find 3inch ones.
