I am curious is it worth getting a flex pipe when you make your downpipe?

 

yes, definitley worth it man..

 

ye sif not the downpipe will break like it did to me twice

they are right the pipe might break for street use it would be smart, but in my personal experience my friends drag ek had problems w/ the flex portion. it kept comming unraveled internaly and resitricting the exhaust even more, but that was under high psi we used an eliminator pipe and worked fine

Either the downpipe breaks or the manifold cracks which is worse.

 

yes, it will help with those large vibrations but the ones of higher frequency that tends to loosen bolts etc.. a flex pipe won't do much for it.

 

agreed. Flex pipe has a lot of advantages over a solid pipe. I am going to use one on my LS-T

 

I didn't like the idea of a ribbed flex section, so I made my own ball and socket that is true 3" and uses off the shelf parts

 

i never had a problem and didnt use them . Exhaust hangers alow the exhaust to move with the motor. That should be enuff.

 

it wouldnt hurt to have one

 

Why dont you like the idea of a flex pipe? It way cleaner than that mess you got going on under your car.

 

Yes a flex pipe or when your moto torques you might crack your downpipe!

 

wow...i didnt know a flex pipe was this important....currently build a turbo setup...where can i find the flex part of it?....i already have a revhard downpipe

Easier maybe, but not any better. The assembly in the photo is about 6" long total, very compact, I can un bolt the whole thing if I want, the gasket is replaceable, and the inside isn't ribbed like your flexjoint, which I already stated in the previous post.

It is a very well engineered piece that will never break, or rot. If you want to call that a mess, whatever...

 

the motor torques front to back on a fwd car it's needed. On a rear wheel drive it's not need because it torques side to side

 

I bolted my downpipe to the backside of the block, so that ****** is rock solid. I did put a flex pipe on the opposing side of the clamp where it clamps to the exhaust though just for safety's sake.

I think that setup is pimp!

thats not a mess at all, maybe a little rust, but a great mechanical design peice in my eyes...

 

would it matter if the flex pipe is on ur exhaust piping instead of it being ON the downpipe?

 

go to kteller.com for the flex piping

 

as someone else mentioned, i would think the hangers would be enough to flex with

 

I am using an 8" flex pipe on my downpipe... I just wanted to be sure that I wasn't going to crack anything... plus I got a good deal on one, only $10!

I am not using spring bolts to connect the downpipe to the cat so I wanted to make sure that there was a little room for movement...

Whether you use a flex section or spring bolts I would recomend making sure your engine has at least a little room for movement other than the exhaust hangers... it's pretty cheap insurance against cracks if you ask me...

 

Damn Jan...that's an interesting piece of work there.

 

I wouldnt exactly call that engineering. And yes a flex pipe wont exactly be smooth on the inside but neither is yours. Everytime it goes from flange to pipe to flange to ball joint to whatever theres going to be a small interuption in flow too.
