Let'* try to keep it practical from now on, or CLEARLY state your intentions from the start.
We can learn more by starting with overgeneralized ideas and narrowing things down to what we want to know. Why get mad over this? It'* absolutely impractical to put a fan in an exhaust pipe, but I asked about it in wanting to know about exhaust flow.
If we need to keep everything practical to keep the thread moving so I can figure out some more things, that'* fine. It'* not too tough to get some use out of my crazy posts, though. rrounds had quoted Scott Stutler, and Paul added some info and quoted rrounds. Considering that, I asked:
"Well, does that mean I can put a 4" straight pipe out of the back of my catalytic converter?"
That may not be a yes or no question. It seems logical, though, to try to explain the effect of 4" piping out of the catalytic converter, if there really is one. I had read earlier both before and after I mentioned 1337ssei'* 3" catback exhaust, about why not to do that until you're in the low 13s or so. Is it just money and weight with a forced induction car?
