Pipe Question

[Philmunsterman]

Guys,

I have two Pipes I can try on the Saw Eagle w/ CMB 100 this weekend. They are both 67 size the steel one has an internal stinger the aluminum on does not. What effect does the Stinger have ? More Back pressure ?

Sorry wrong forum. Can someone move this to the Outrigger forum. Thanks

I've found no difference running internal stingers for 10 years now, the extra length makes no difference that I can see, only the I/D.
