2002 saturn sl exhaust system its located under the manifold but above the cadilitic converter... It looks like a stainless steel mesh and flexible, its 2inch pipe by 8 inches long


guessing you are referring to the flex section of the exhaust pipe that allows engine movement separate to moving the exhaust system
it is a stainless steel convoluted section enclosed insulation by the mesh and are subject to failure from work hardening of the stainless steel section from improperly maintained exhaust system mounting rubbers ( broken)
can be replaced by any accredited exhaust repair shop

How much does it cost for the exhaust


Most after-market exhaust companies offer four types of components:
  1. Cat-back exhaust systems - anywhere from $300 to $1200 - The final cost will depend on steel thickness and type, as well as muffler quality.
  2. Axle-back exhaust systems - same as above
  3. High performance mufflers - $75-$300 - The quality of the muffler's materials inside, as well as the type of steel and thickness used, impact the final price.
  4. Exhaust system tips - $25-$150 per tip - Almost all cat-back or axle-back systems include a quality exhaust tip. However, if you're building your own system, you can purchase an exhaust tip to "dress up" your factory pipe.
The schematic below shows where the "cat" (a.k.a. catalytic converter) is in relation to the engine. While many companies sell high-performance catalytic converters, they are fairly expensive and usually don't restrict exhaust flow too much, so we're not going to worry about them here.
alt="Exhaust system schematic with notes">

This is a stylized schematic of an exhaust system.
On some vehicles, the muffler is mounted behind the rear axle. In this case, exhaust manufacturers sell "axle-back" systems. The only difference between a cat-back and an axle-back exhaust is the length of tubing - both include a new muffler. Therefore, there's not a lot of cost difference between the two. Both cat-back and axle-back systems include tubing, a muffler(s), and then all the hardware needed to mount the new system in place of the factory system. Most of the time, these systems use the factory exhaust hangers to make install as easy as possible.
Since a high-performance muffler is a part of a cat-back or axle-back exhaust system, buying a muffler by itself is usually the least expensive option in terms of parts cost. Keep in mind, however, that mufflers have higher labor costs. They're not necessarily less expensive by the time all the labor costs have been accounted for.
Muffler Only vs. Cat-back or Axle-back The biggest advantage in purchasing a full cat-back or axle-back system is that install is really simple. Many of these systems can be installed at home with basic tools. Conversely, installing a muffler at home may not be so simple - cutting and welding may be required. What's more, some after market mufflers require significant re-routing of your stock exhaust tubing...and that can get expensive very quickly.
The other advantage in a full cat-back or axle-back system is that they are often tuned to your specific vehicle and the included muffler(s). All things being equal, a cat-back or axle-back system will perform slightly better than a muffler only.
Stainless Steel vs Aluminized or Galvanized Steel The main difference between a stainless steel exhaust system and an aluminized or galvanized system is durability. Stainless systems will last a lifetime due to their ability to resist corrosion, with 200 300 series stainless systems being more resistant than 300 200 series systems (only the difference is slight). Some manufacturers will try and convince you that one type of stainless system (200, 300, or 400) has better sound quality than another, but there's no evidence we're aware of to support these claims. In fact, stainless steel tends to be slightly thinner than aluminizied steel. If anything, an aluminized system may have better sound quality.
Having said that, the muffler itself is the biggest factor in sound. The steel used in the system isn't as important as some make it out to be (at least in terms of sound quality).
When it comes to choosing between stainless and aluminized systems, it's important to consider your local environment. If you live in an area where corrosion risks are high (such as cold-weather areas that use salt to de-ice roadways), stainless steel may be a reasonable upgrade because it will resist rust. On the other hand, if your local environment is dry and the corrosion risks are low, the only reason to buy a stainless system is for looks.
Exhaust Tips There are probably thousands of different exhaust system tips available. Generally speaking, you get what you pay for. Stainless steel tips are very resistant to corrosion, but they don't shine up as nicely as chrome. Also, stainless steel tips are more likely to "blue", or change color during use. Titanium is also a material used to make exhaust tips - it's incredibly corrosion resistant, but just like stainless it's prone to blue during use. If you like the blue coloring, titanium is probably your best choice. If you want the shiny look, chrome is the way to go. If you want a tip that you can shine up every once in a while - but that's also resistant to the elements - stainless is a smart choice.
Exhaust System Labor Costs If you purchase a cat-back or axle-back exhaust system, labor costs are often very low. These systems bolt-on and use the existing factory hangers. In fact, many performance shops will install a cat-back exhaust system free of charge if you purchase it directly from them.
If you decide you want to purchase a muffler only, you'll want to get an install estimate from your local exhaust shop BEFORE you buy that muffler. Sometimes, installation is very straightforward and the cost is as little as $100. Other times, fabrication is required and the cost can be as high as $300 (or more). If the installation requires a lot of fabrication, you may be better off buying a cat-back or axle-back system instead.

My toyota echo 2000 is in great shape but if start it run or accelerate it then its too loud.... but we check the muffler has no leak...


check for a crack in the manifold to exhaust pipe connection
to allow the engine to move ,there is normally a flexible piece of exhaust pipe in a stainless steel braid that cracks and allows exhaust sound out especially on acceleration
could be even broken at the manifold connection at the flange

1998 Cadillac Deville exaust cross pipe replacement


1) Take it to a muffler shop unless you are a good welder.
2) Procure the new exhaust pipe material.
3) Make the necessary bends in the new pipe to correspond with the layout of the old pipe with a hydraulic tubing bender.
4) Use a band saw to cut the new pipe to lengths using the old pipe as a template.
5) Weld the pieces to form the crossover.
6) Using a cutting torch, cut both exhaust pipes to the length you made the crossover.
7) Weld in the new crossover you just made.
8) If you can't weld with a torch, have no access to a tubing bender and have no way to get the correct exhaust pipe material....take the car to a muffler shop.

Stop leaking?


There should be rubber hoses at either end of the metal pipe to allow for engine ,movement. It would be black steel pipe and it rusts out from lack of coolant conditioner.. A final fix for this would be to take it to a muffler/ exhaust shop and have a new pipe bent to shape made out of exhaust stainless steel tubing

Tailpipe is hanging very low


Hi. Under or near the tailpipe, there are rubber and sometimes steel hangers that are placed onto the sides of the pipe structure. These move with the assembly to provide little flexibility during travel. These hangers also are there to keep the pipe/muffler assembly from dragging or hanging to low. When the hanger assembly becomes unstable or damaged, it will allow the tail pipe assembly to hang low or sometimes drag the ground when you hit a bump. The necessary actions are to raise the vehicle high so that you can inspect the exhaust tail pipe assembly for broken hangers or steel bracing devices. replace any rubber hangers that may be snapped or missing form their respective locations. If you are uncomfortable with raising the vehicle, i would take the unit to a local muffler/exhaust shop for the inspection.

Took my expedition to a tranmission repair shop for a leak. They they inform me I need a totally new exhaust system (cost over $800.00), but when I brought it in, the pipe connected to the muffler had...


You can remove just the rusted sections, Usually the exhaust system from the engine back to the converter,is what is called 409 Stainless Steel. It gets a little rusty but never needs to be replaced. On some vehicles, you can remove everything from the converter back,as you believed was bad. That would be a pipe,then the new muffler,then the new tailpipe. Those three are carbon steel and rust,not Stainless. I would go to a close by repair shop and not a big franchise or chain. There pitch men. Not that they don't do good work. The $800.00 is the Ford parts price for a whole new system,end to end,which you never need. Some cars are all welded,so that's for another day. Yours should be clamped on at the converter. Most of the time the vehicle owner does not understand the terminology used and the people explaining it, are so used to abuse, from the motoring public,that they fail to educate you,on any level. The mufflers is about $100.00,the pipes about $35.00 ea, $250.00 Total,with labor.

Possible cracked manifold


Take it to a muffler shop, they work on exhaust problems all the time and may just need a new gasket from the collector flange which would not be that expansive. Almost all of them will inspect for free since there looking for your business.
I have not sean exhaust manifold go bad before the whole car or truck and the exhaust pipe is stainless so good chances are that it's the flange gasket or the bolts may have broke due to time and vibration.
Good luck and keep me posted.
