Exhausted Question

[Funmart6]

What is the purpose of the flex pipe on our cars?

it has to give somewhere am i correct unless u have solid motor mounts

It is to allow for the normal movement of the motor without separating the exhaust and causing leaks.

The reason I asked this question was because I wondered why older vehicles didn't have flex pipes? Is it a "technology " thing? I have a 1968 Dodge truck with 60,000 original miles, completely original, no flex pipes under that thing and never an exhaust problem. Had an '89 Taurus GL a few years ago and it didn't have a flex pipe either, so I was just curious as to what the flex pipe is there for?

front wheel drive vehicle have the engines set in side ways compared to rear or most
4 wheel drive vehicles. the twisting movement of the engine in these vehicle is all taken
up in the exaust hangers usualy made of rubber. it is more of a side to side torque put on the exaust system. on front wheel drive it is a up and down movement. if the pipe wont flex at the stress point it will break. i dont believe they are crucial my two shos dont have a flex pipe either but the point after the y pipe where it joins the single pipe going down the middle of the car the flang has worn out has holes in it. could of been a problem that ford fixed

my shos are 89,92 mtx
