Your go-to spot for information on the exhaust system, as well as mufflers, catalytic converters, pipes and sensors. Walker is your one-stop exhaust shop, offering a full line of mufflers, pipes, hardware and accessories. Secondly, the only real way for my to insert the coupler into the flexpipe side, is to slightly bend the flex pipe, a pipes-width width so the I can slide it in. Keep in mind that the bolts holding the flanges together are completely rusted over. With the flex pipe the exhaust system can move a bit, ridged mounted it will break welds, flanges or worse headers. Because the muffler and the piping have been held together with the exhaust clamp for so long, they may not come apart easily once the clamp is removed. Spray some rust penetrator where the two pipes meet and try to work them away from one another until they slide completely apart.If the pipes are rusted together, you may have to cut the pipes apart. Sandpaper will remove any last bits of dirt and debris stuck to the pipe while scoring the steel surface to better stick when you apply the patch. Rub 80 or 100 grit sandpaper back and forth along the exhaust pipe around the leak you intend to seal.
Be careful not to drip acetone in your eyes or mouth while cleaning the pipe with it. If you are using exhaust tape, make sure to scrub the top of the pipe as well. Scrub the pipe all around the leak, including the top side if you can reach it. Keep your hands away from any moving parts while working beneath a vehicle with the engine running. Rust can cause serious exhaust leaks if allowed to penetrate all the way through the steel. Never jack up a vehicle on an uneven surface or the car may fall off of the jack.
Most shops will be limited to bolting on OE-style parts. An exhaust shop, on the other hand, would have more options as far as fabricating or adapting cheaper universal parts, if state regulations allow. This post is all about how to fix exhaust pipe without welding. I understand welding or getting a new exhaust could be quite expensive. But this method I have just highlighted won’t get you to break the bank. The process is also quick and straightforward, as you can see from the explanation. It will buy you some more time to save up for a new exhaust or do other repairs on your exhaust pipe.
Exhaust Flex Connector Extension Pipes FORTLUFT consists of four layers. The outer and inner layers are made from the weaving stainless wire. Between these layers, there is a double layer bellow, also made of stainless steel. Standard Caps with connectors are installed on both sides of the exhaust flex pipe. They securely fasten all four layers and allow them to integrate this spare part into the exhaust system by welding pipes or clamps. Our Verocious Motorsports Universal Exhaust Flex Pipes are your solution for cracked exhaust pipes. Whether repairing damaged OEM exhausts or building a custom exhaust, our high quality stainless steel flex couplers are more than capable of handling the job.
Be very careful not to drip acetone into your eyes or mouth while wiping down the pipe with it. If you are using exhaust tape, make sure to scrub the pipe all the way around with the sand paper. Scrub the entire portion of the pipe around the leak, including the top side if you can reach it. Cracks in the piping are another common cause of exhaust leaks. Slide a scissor or trolley jack below the vehicle at one of its designated jack points. If you are unsure where these jack points are, refer to the vehicle’s owner’s manual to help you locate them. With the jack in the correct space, jack up the car until it is high enough to safely work beneath it.
Moreover, there is no need to remove the whole exhaust system. Only to cut out the failed exhaust flex pipe and install a new spare part using the welding method or clumps instead would be enough. I fixed my problem by purchasing a Nickson Flat Band Exhaust Clamp at Advance Auto, along with some Hi Temp exhaust sealer putty. Nobody carried the diameter clamp I needed, so I purchased a large one and cut it down to size. After grinding the rust off the cracked exhaust pipes, I coated it liberally with exhaust putty and installed the clamp. The 2 pipes are totally separate, but right next to each other. My exhaust pipe in my 2007 maxima has a crack about an inch outside of a flex pipe, and the repair cost is more than the car is worth to me. My engine and transmission are mounted on poly bushings.
If you can’t find the leak in the exhaust pipe with a visual inspection, leave the vehicle jacked up and start the engine. With the engine running, you should be able to quickly and easily identify the source of the leak. If you aren’t able to easily identify the leak in the exhaust pipe, use the vantage point you gained jacking up the vehicle to visually inspect the piping and muffler. Look for signs of damage that may indicate a leak such a deep rusting, cracks, scrapes or holes. Detach the exhaust pipe from the exhaust manifold from beneath your Volvo. The exhaust pipe links to the manifold with two bolts, which can also be taken off with a common wrench. Next, pull out the exhaust manifold and detach the exhaust pipe’s hanger.
I had never welded before, but it wasn’t as hard as I thought. It was $100 or so, but now I have a welder, and a car that sounds good. Note that you might still need something to put over any holes. It’s near impossible to patch more than about the thin side of a quarter. Personally, I’ve never had much success with any type of bonding compound. Since the exhaust heats up considerably, the pipe will expand and contract, which tends to foil any plans relating to compound. Here are a few other methods that I’ve found to work better though. There are a couple hack-y fixes for exhaust problems, especially since the exhaust system isn’t a crucial part of the car and the world won’t fall apart if it breaks again. FWIW, on my truggy I’m running all V-bands and my exhaust is hung, but it’s a steel strap – so not much give.

After installation, the exhaust flexible element should be checked for any damages and the exhaust system should be checked for leakages. In addition to the exhaust flexible pipe an inner metal lining can also be used instead of an inner braid. Such a rigid lining also prevents the corrosive exhaust gases from damaging the metal flexible bellow.
Brush the sand and other particles off your exhaust, but ensure you are wearing eye protection before you go underneath the vehicle unless you don’t mind having some dirt and grease in your eyes. However, if you are dealing with a broken exhaust pipe, then you need to try something different. So, yes, you can fix your exhaust pipe without welding it, and it would last for a considerable period. Our comprehensive range of flexible tubing suitable for use in exhaust applications, electrical conduit, and for transit of flour, grain and ash. The manifold itself had flexible expansion bellows between cylinders 1-2 and 2-3 but not 3-4. That would only help if cracks are caused by leverage from the downpipe. Well in fact a flex is often used by several OEM’s, but if the car isn’t designed for it it shouldn’t need it. Might have something to do with those cats built into the manifolds on those early years. Walker offers various types of pipe and tubing like our premium pre-bent pipe with OEM routing and hanger positions, flex tubing that provides leak-free applications, to ALS and LCS straight tubing.
In a state that has snowy winters and uses road salt, rust will most definitely shorten the lifespan of the flex pipe, along with much of the rest of the vehicle undercarriage. Front-wheel drive vehicles and most all-wheel-drive vehicles use a flex pipe in the exhaust system. The flex pipe is necessary to allow the forward and backward rocking of a car engine on starting and acceleration. It’s not always easy to notice a flex pipe exhaust leak or even when it starts to break down in the first place. Here are some tell-tale signs that your exhaust flex pipe is leaking. It’s a flexible piece of pipe that creates some flexibility within the exhaust system. They are typically made out of forged or stainless steel. Forged steel 150# flanges are rated for pressures up to 285 psi at 100 degrees Fahrenheit, according to ASME B-16.5 flange specifications. The allowable pressure is reduced to 65 psi at 850 degrees.
The biggest issue with an exhaust leak is its terrible sound. The leak will also affect the performance of the car as a result of loss of back pressure if its large enough. With the piping seated properly, slide a muffler clamp over the area where the muffler pipe overlaps the other. If your muffler was welded in place, you will have to cut the pipes apart. Wrap exhaust tape around the leaking portion of the pipe. If you are using exhaust repair tape, wrap it all the way around the part of the pipe with the leak. Continue to wrap the tape around the pipe for a few inches to either side of the leak to ensure there is a good seal. Different kinds of exhaust repair tape will require different application methods, so be sure to read the instructions before you get started.
