It could also be a result of rusting, which would weaken the strength of the exhaust pipe and cause it to break easily. The reason this is important is due to the natural laws of physics. When the metal piping of an exhaust system and headers heats from the hot exhaust gasses passing through it, that metal expands. In the reverse, after the engine is shut off, that piping cools, and the metal contracts. Exhaust flex pipe sections are widely available at automotive stores in a variety of lengths and diameters. To answer my own question, while flexpipe does flex, it is not meant to be flexed more than a very minimal amount, enough to compensate for any vibrations in the exhaust system. I tried very gently to flex it and it only moved a drop, so I went another route because I din’t want to bust the pipe.
On some engines, the flex pipe may use slip joints with a clamp at one or both ends; requiring the need for some exhaust tools to replace well. The flex pipe usually fails by breaking internally, which then, causes an exhaust leak and noise. This engine is a V-6 and the flex pipe is part of a sturdy y-pipe that joins the two exhaust banks. This is less suitable for a cheaper aftermarket universal flex pipe that could be welded in. The labor time to replace the flex pipe is estimated at 0.8 of an hour.

Make sure to coat the perimeter of the patch with epoxy at the least to ensure there are no pinhole leaks. Make sure none of the leak extends beyond the sides of the patch. Apply the epoxy to an area surrounding the leak that is equal size to the patch you are applying. Wrapping the can or patch all the way around the pipe will provide the best seal. If you purchase a patch kit, make sure to read the directions to assess the size of a leak the kit can fix. If the area that needs to be patched is larger than about three inches, that portion of the exhaust will likely need to be replaced. Different types of epoxy have different curing rates, so read the instructions on the package to know how long to allow it to sit before driving the vehicle. If you are using epoxy to seal the leak, mix the two parts together using a wooden dowel. Once the two parts are mixed, it will begin to cure immediately, so apply it to the leak quickly.

Volvo is still manufacturing quality driven and superbly designed vehicles. You Volvo’s exhaust pipe is mainly in charge of transitioning and pushing out the noxious exhaust gases created by your engine away from the inside of the vehicle. Basically, they keep the harmful gases out of your lungs and keep the interior of your Volvo safe of fumes. Exhaust pipes also work to redistribute the exhaust gases through your Volvo’s muffler in order to quiet down the noise created by the gases. In most vehicles, they redistribute exhaust gases through a catalytic converter, which is developed to reduce your Volvo’s emissions. When a faulty muffler or catalytic converter has broken down and needs replacement, the first step is to take off your exhaust pipe. The first thing to do is to lift up your Volvo with a floor jack and place the weight on the jack stands. Use a wrench to take off the exhaust manifold from your Volvo’s cylinder head. The exhaust manifold is attached to the cylinder head with a few bolts.
Acetone will ensure the metal is clean and free of anything that could interfere with the seal created by the exhaust tape or epoxy. Acetone is the primary ingredient in nail polish remover, so you may use nail polish remover for this step if you’d rather not purchase acetone strictly for this project.

Use a steel toothed brush to scrub away the grime, being careful not to get any in your eyes. Once the exhaust is cool enough to work on, slide a scissor or trolley jack under one of the vehicle’s rear jack points. Once in place, either lift and lower the handle or turn the handle to jack the car up. In order to repair an exhaust leak, you will need to jack the vehicle up to locate it. Always jack vehicles up on flat, level surfaces to ensure the jack won’t topple over as you lift the vehicle. It is also important to ensure the surface is sturdy enough to support the weight of the vehicle beneath the jack.
A factory replacement part is about $477, and a Walker replacement part is about $141. The total cost to complete the job would be about $597 using factory parts and about $261 using aftermarket parts. The labor time to replace the flex pipe is estimated at 1.3 hours. A factory replacement part costs about $231, and a Walker part costs about $79. The total cost to complete the job would be about $362 using factory parts, and $209 using aftermarket parts.

A factory replacement part costs about $1312, and a Walker CARB compliant part costs about $295.
Just get a flex pipe that can pass through the exhaust pipe. And there should not be too much space between the flex pipe and the exhaust pipe after fixing the former. Also, after setting the flex pipe, you can now attach the clamps and tighten them. just make sure the exhaust system is well suspended . Automotive engines move slightly during operation, whereas most exhaust systems are fixed from the mid-section back. Flex pipes allow the engine to move and not crack or rupture what would otherwise be an inflexible metal exhaust pipe. Flex pipes are typically found where the exhaust manifold meets the downpipe or mid-section of an exhaust, which is closer to the engine than to the exit tailpipe. The main purpose of the exhaust flexible element is to absorb vibration and to provide expansion compensation for the exhaust system.
