I still dont see how a flex pipe is gonna help anything if i bottom out, considering the flex section is horizontal mainly and bottoming out would be verticle....and how much does it really matter if its ribbed or not inside

I don't know, I was only referencing from first hand experience with the supra. I came to a logical conclusion from my own experiences trying to help someone out, wasn't trying to start an argument or anything.
i guess by eliminating ANY movement. i already have a 3 inch flex section (SS),and the turbo flange by Lipp. I just need to find a full 3' Dp.drumminforev said:
fozbo is correct if you think about it...the tranny doesn't flex seperate from the motor, and the stock dp is bolted to the turbo and the tranny with the flex section in the middle....there shouldn't be any flex between the motor and transmission. I don't have one, no problems getting the dp on or off and I haven't cracked the turbo/manifold.
In conclusion. I'd say that it's all preference. If you think something might happen to where you'd need a flex section then get one, if you don't want one then don't. If you get a smooth flex section it's not gonna hurt power at all, just costs a little more.

i can only guess not by much...but after i dunno 5 years or so u might see a big diff.
just get it to be on the afe side.
your alrdy dumping so much money into your engine etc etc (saw your list), why not spend a couple more bucks on this particular matter.
Typical flex pipe found at any autoparts store, or at summit racing:
This is the truck type used on heavy duty applications and over-the-road semi's:
(i can see how you guys couldn't find it... it took me like 20min to track this one down)
too bad it comes in a 5' roll though...

Well if its 50 bucks then it doesnt sound worth it.oscolivar1 said:
Where can i find some smooth ones like this
BTW that coil of shit doesnt look anything like the flex pipe section right about it.
This is what you want:
http://cgi.ebay.com/ebaymotors/3-St...0QQihZ002QQcategoryZ33633QQrdZ1QQcmdZViewItem
Note the inside has the solid flex...the outside is a mesh reinforcement.
This is what you don't want:
http://cgi.ebay.com/ebaymotors/3-x-...8QQihZ003QQcategoryZ33633QQrdZ1QQcmdZViewItem
The inside is the same mesh as the outside...not good for flow or allowing gas to escape...it's cheaply made.
You will not see any gain or loss from using a flex...HP wise, it's neutral. I use one because I do not want any chassis vibration or movement to be transferred to my turbo/exhaust manifold. Like I said, it will stress the hardware and we have enough trouble with the studs holding the exhaust manifold loosening up as is without adding additional stress from the chassis. What it comes down to is do you think this is important...as much $$$ as I have in my motor, $50 is noise level. A downpipe will work well if there is no restriction, has quality welds, and hugs the bottom of the car...regardless of flex or not.

I see the diff, why does the first one even have the mesh on it since its gonna expand and contract anyway?
Are you saying the vibrations from the tranny would stress the manifold without the flex pipe, if not where are the vibs coming from because the rubber hangers would absorb all that come from the chassis

The mesh is there mostly for looks...it does provide some additional support, but not a whole lot. I wanted you to see what not to get.
Yes and the rubber hangers also allows the exhaust system to move when you hit bumps in the road. Or if you happen to bottom out the downpipe. I use a flex for the added insurance...you don't have to use one.
Most quality downpipes (cooleze, BIC, etc.) either come with a flex or is an option.

that's pretty funny. I made half an exhaust for my winter beater (91 cavalier) out of that roll of flex crap. $50???? I bought a 6' long piece 2.5" inner diameter for like...$11?
The stuff I linked to is stainless, and 3"
But yeah, I know what you're talking about. That stuff rocks for making a "custom" exhaust for a beater.. lol
my brother's chevette had nearly an entire exhaust made out of it.
