Flex pipe replaced four times within five years

Hello again,

As a general rule, flex pipe doesn't have the life expectancy that regular exhaust pipe has. This is do to it's nature, it is flexible, so in order to make it flexible, thinner materials are used. Thinner materials with multiple joints that enable the pipe to flex is not going to withstand the constant heat of a vehicle's exhaust as a thicker solid piece of exhaust pipe. It's just the nature of the beast. I would recommend seeing if there is any way of getting exhaust pipe bent to the specs you need and give that a try.

Thanks,

Good evening,

Just wanted to add to Alex response.

A lot of the times, those flex pipes fails from too much movement from the engine. Weak motor mounts will cause the pipe to flex way too much and it fails.

The reason for the pipe is movement of the engine. Since it sits sideways, it moves and if they did not have a flex pipe in the system, a pipe would actually fail.

There are several motor mounts on the engine. You have 3 mounts on the transmission and 1 one the engine. Any one of them with too much play can cause this issue.

You are welcome.

Always glad to help.
