[s-cars] Exhaust banging - APR snub mount

I had this problem when I first got my S4 (no Strumong), I had the exhaust
alinged and never heard it since.

F.Y.I.
APR Snub mount at APR $50
http://www.goapr.com/Audi/products/engine_mount.html
<http://www.goapr.com/Audi/products/engine_mount.html>
Or at ECS, same price:

Any other polyeurathane mounts available? Sure sounds like a neat little mod
!

	Hey eh Joe, where you gonna run to now.


	Man, when we talked about this last week, Joe told me he hit a speed
bump hard enough to crack the exhaust near the cat. Heard some ticking
noises and such. I suppose if that's true, he bent that unruly pipe, no?

	Recall Frank wrote about the snub mount last year, and reminds us
often. It provides a stiffer mount for the engine nose, to prevent excessive
twist, under load. This should be required for all of us, whether Stromung
or not.

	I've had some exhaust interference lately, too. Hit a
	bump and have had a loud vibration coming from the cat
	area ever since. I'm going to try putting the
	straight pipe on tomorrow (emissions tests be damned,
	I "know a guy") and see if that helps things. Tell me
	more about how this engine mount is gonna help guys
	like you and me with unruly PostoSport Exhausts?

	Thanks,
	Joe
