Default Old OEM exhaust Info W/Pics

So I always wanted to confirm the info about the OEM exhaust, Prodrive components, Stromung, etc. Now I have and here are some pics:

First, any long downpipe or center pipe that ends with a donut has the following internal diameter...



The above happens to be the Prodrive center pipe.

Next, the OEM rear/resonator pipe has the following internal diameter at the outlet:



Then the Stromung rear pipe,2.5" has the following outlet inner diameter:



Enjoy my old Diesel Mercedes in the Background..

Then Stromung VS OEM, at the inlet:



The Prodrive Axleback has the following inlet inner diameter:



I think this is interesting info, even if it applies to old cars...
Next I will take a look to see if the OEM resonator is baffled or straight-through..

The OEM resonator is a straight-through design, no baffle.

Old means that the GDB cars are now old
And yes, it's just info, as some manufacturers give you 2.5" inner diameter in a 2.5" exhaust, some outer diameter and the info about the OEM exhaust was never too clear, if you ask me..

And thanks, more to come..

Cool! I'm running Syms Racing JDM length downpipe-->stock donut gasket-->stock JDM midpipe-->Prodrive oval tip. This combo fits perfect together and is very quiet!

Good stuff, thanks...
If you guys keep adding to this thread, I'm thinking to change the title into something like "exhaust inner diameter database".
