Flex pipes

[GhostAccord]

hey foamy I wasn't referring to you when I was talking about people assuming things.

The Donut/Spring setup is essentially a "flex pipe."

It is what a lot of new Hondas use stock.

I'm not "assuming" or going off of other peoples thoughts.

Every production vehicle on the planet has one. I think it's kind of important.

But I am a wee bit What are you trying to say in these two posts? Is it that every new car has a donut/spring setup or flex pipe? I think you may be contradicting yourself in these two posts.

Its not so much the rubber hangers as much as even the welds on the headers even that would have a much larger chance of getting cracks.

If you buy a quality header that has the rear mount that connects to back of the engine block then you will never have to worry about the header welds.

why would you buy a brand new header and cut it up to get rid og the flexpipe? anyways unless you had to or something?

Ah, gotcha Ghost.

What I meant was that every production vehicle on the planet has some sort of assembly, whether it be the ball/socket type, or a flex pipe, that allows the exhaust to move independent of the engine.

Even if you have the braket that holds the header to the block which even the cheap ebay ones have........ It will just brake that off first. You need somthing because the engine moves way too much and the exaust doesn't so much. Just replace it with a larger diameter if you care so much about it "killin' maahh horsepowerz"

if you do not have a flex pipe or some other flexible joint you WILL damage either your header, exhaust piping or muffler. The only way it would not happen is if you run solid steel mounts.

or something that holds your engine sturdily without movement.

Yes you need a flex pipe, like stated above it dosn't matter what type as long as it can pivot and reduce stress in the exhaust.

If you look at a stock f22 they rock back quite a bit, polyurathane motor mounts cuts down on the rock giving a little more freedom when it comes to which flex pipe.

But as a word of warning, when i had my custom system built the guy only had flex pipes about half the size of stock, without me knowing he just installed that... and 2 hard pulls later i had tore the bottom out of the flex pipe... making my nice exhaust last a whole 2 days. so make sure its long enough to handle the movement of the engine.

I didn't run a flex pipe on my civic. Never had any problems.

you are aware that civics do not use them because they have a flexible joint between the header and the exhaust....?
