Best Muffler & Exhaust Services Near You

If the rest of the pipe still has metal in it, welding in a new section is the sensible repair and it lasts. If the system flakes when you tap it, patching one hole just moves the leak along a foot. Ask the shop to put the car on the lift and show you, because rot is easy to see and hard to argue with.

Something opened up. A rotted seam, a cracked flex pipe, a broken manifold stud, or a converter that was cut out of the car while it was parked. Loud with a fume smell inside the cabin is the urgent version, because exhaust gas under the floor is dangerous. Get it looked at rather than driving with the windows down.

A rotten egg smell, a warning light for converter efficiency, sluggish acceleration as if the car is breathing through a straw, or a rattle from inside the converter when the ceramic breaks up. Converters usually die because of something else, so a shop worth the money finds the misfire or the oil burning first. Otherwise the new one goes the same way.

They sit in the pipe and tell the engine how much fuel to add, and a second one grades how well the converter is working. A lazy sensor costs you fuel and can throw a converter code even when the converter is fine. They also seize into the pipe, so an exhaust shop often ends up replacing one during other work.

Yes, and the good ones will tell you what you are trading away. A freer muffler adds volume everywhere, including at a steady cruise, and that drone is what people regret. A resonator tames it. Removing emissions equipment is a different matter: it fails an emissions test where one is required, and no reputable shop will do it.
