If you are racing cars it's very important.  For our purposes, this doesn't
seem to make a big difference.  I had a 1.75" headers into 2" collector
which worked pretty well and sounded like music with a cherry bomb glasspack
(for about 5 hours).   I use a 1.75 to 2.25 on the 20B.

On the Renesis it is almost literally a non factor due to the lack of any
I/E overlap.
