I'm not a big fan of removing kitty's, but why not if
you don't have to have them.  I an exhaust upgrade is
a must, I've said this before, I just had a glasspack
put on my car to reduce noise.  Well the shop decided
to put the 2" version on since they were too lazy to
order the proper three inch and hope I didn't notice.
I lost 2-3psi of boost and spool up sucked!  I went
back and demanded they replace it, sure enough back to
normal.  Just shows you what a little restriction will do.
