You claim you don't get answers.

You haven't answered my question regarding what hasn't been answered. You had one other thread here and it was answered with replies that were on topic. You started three identical topics within minutes because you either didn't like or understand the answers you got in the other thread. Why didn't you pursue the other thread if that was the case?

How that is not being argumentative, I don't know.

This is done. Good luck with your exhaust build.
