[Shotimes] muffler shops and flex pipe

[Eric Keller]

The problem with opening up the exhaust too much is
you have to fill it with more exhaust.  Gutted cats
would also make downstream back-pressure more
important. As I understand it, the resonator is a
pretty important part of the exhaust performance, and
certainly has a large effect on the way the exhaust
sounds.
