Type IV exhaust stub pipes

[CactusCurmudg'n]

I took a look at StaggsRacing's stub pipes. They appear to have a very heavy
wall thickness. Do you know what the dimension is? Since one of the
advantages to a stub pipe system is increased gas flow with a pipe ID that
is less than the factory item, a very thick wall for the stub pipe defeats
this. If we can get some more details I would be interested in participating
in a group buy.
