Flex section in down pipe
Well I have been meaning to put new springs on my car to address the low ride height, to little to late! A speed bump pulverized the flex section on my down pipe.
Im about to send the car to the muffler shop to have the flex section removed for a solid pipe.
So the question is how important is this flex section? FM doesnt do it so I assume its not necessary..

Not saying anything against manufactures but they all have reason for all that they do.. from my observation BEGIs manufacturing Specs seem to be alot looser then FMs. I assumed that they used the Flex section for that reason.
But of course I have never read of a cracked BEGI manifold like I have of FMs and I read that not having one can put extra stress on the manifold so Hmmmmm????????
I really am just looking to hear from people that ran with and with out one to see what are the benefits.

I've tried both ways... 1st the stock Greddy downpipe mated to stock Mazda downpipe, then an upgraded 2.5" replacement downpipe.
Neither of the above had flex sections and I ran the car that way for well over 2yrs with no problems.
Just got another downpipe recently and this one DOES have a flex section in it.
I don't know why but I feel better knowing the exhaust has the flex-pipe in it now.

I am not quite sure how to phrase this w/o sounding like the ah that I tend to be.
Maybe this:
Is the system better with a flex joint?
Are vibrations likely to be less?
Is it easier to line up the fit?
If your intentions were to build the best parts, would you put a flex joint in the dnpipe?

i bought a "turbo" flex pipe for my miata. previously i used normal flex pipes on my dsm's and turbo honda's. the turbo version has a flexible steel sleeve inside that's smooth when straight, but opens up when it flexes. think of your dad's or grandpa's watch band. the kind that would pinch your skin. yeah, like that. supposedly they are quieter and last longer than standard flex.
