(Make sure the alignment marks are far enough away from the repair area so that while cutting out the rusted pieces you wonвЂ™t damage or destroy the marker lines)ДЄfter I have all my measurements down I began to cut off the old repair by using a cut off wheel on an electric angle grinder to cut off the rusted patch piece then a grinding wheel to smooth out any rust or metal that is still remaining. This is very important because without these marks as a guide it is nearly impossible to make the repair and maintain the correct angles so the hangers will line up and the exhaust tip will sit square and even in the bumper cutout. Not shown in this shot, I also drew lines on either end intersecting the first lines I then measured the distance between each of crosses and wrote them down for use later.

I then used a metallic permanent marker and straight edge to draw lines the length of the area that needs to be replaced. As you can see here the rust is very bad and in order to properly fix it the entire section must be cut out an a new piece of pipe will need to be welded in.Д«efore I started cutting away the rusted pieces I clamped the resonator down to my workbench and held the broken pieces together in the correct orientation. With the pieces on the table I was able to get a much better look at the condition of the pipes as well as figure out the best way to fix the problem. This was done be removing the factory band style clamp which is in front of the resonator and also by two hook style hangers which were holding up the muffler and exhaust tip. To tackle this exhaust repair I first had to get the rear portion of the exhaust system out from under the car.

When working on cars its always best to take your time while doing repairs because when a repair is done correctly it will never appear again allowing you to be worry free when driving your car. Fixing your exhaust system like this may work temporarily, but in the long run it will always come back to bite you. Once the weld from the original patch job broke a band style clamp was put over the pipe to reconnect the pieces but neither repair was a success. In this article I will show you step by step how you can repair a damaged or rusted out exhaust system so it will be able to withstand the elements and be able to drive without the worry that sooner or later you will need to fix your exhaust system.ДЄs you can see here this exhaust system was not mended once but twice, both times improperly. The fix was done very poorly and slowly but surely it rotted away, leaving the muffler suspended by the hangers, completely disconnected from the rest of the exhaust system. At some point one of the previous owners must have installed an aftermarket exhaust system in place of the stock unit and when it was time to sell the car a quick repair job was done to re-attach the factory muffler. The car slowly became louder and louder until eventually it sounded as if there was no muffler on the car at all. The seller was not lying because it did have the factory exhaust but what made itself very apparent is that the factory installed muffler spent some of its life off of the car.

I encountered this issue when this car was purchased claiming to be вЂњstockвЂќ. It is tough to know everything that has been done to a car by the previous owner/ owners.

You may also encounter exhaust issues when buying a used car. These welds can hold for years but eventually, like all steel does, it will rust out.

The exposed steel welds become much more susceptible to rusting once they come in contact with water, salt, mud, or anything else you may drive your car through. are done with mild steel welding wire and are not treated to resist corrosion. The tubes themselves do an вЂњokвЂќ job of resisting rust but more often than not the welds joining the aluminized pipes to mufflers, resonators, flanges, etc. From the factory many cars are equipped with what is called aluminized steel exhaust tube, this type of tubing is much better than mild steel tubing because the infused aluminum helps resist corrosion and rust from forming. Nothing is worse than the constant ticking sound that is the most apparent symptom of a damaged or broken exhaust system. Unless your car has a factory stainless steel exhaust tubing it is only a matter of time before the elements compromise the integrity and functionality of one or many parts of the whole system.
