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 h=
ard 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
