Frequently Asked Question

If your vehicle gets considerably louder as you accelerate, it might be time to get a new muffler. The noise alone isn’t enough to identify the source of your problem but it’s enough to let you know that you should have your vehicle checked out.
If your vehicle was manufactured in the 90s or later, its muffler is probably built from stainless steel. The newer your vehicle is, the more likely it’s being controlled by computers that make it easier to gauge the progression of your muffler. On average, you can expect it to last for years or even the entire lifetime of the vehicle. Of course this varies on where you live and the overall condition of your vehicle, but if you want to be sure, contact one of our professionals.
This is completely normal. It’s likely water condensation draining out of your car’s tailpipe. However, if you are still concerned, feel free to bring your vehicle by for an inspection.
If the damaged muffler causes some sort of obstruction in your vehicle’s exhaust system, you may notice a decrease it its MPGs and performance. If it continues to worsen, your vehicle may cease to start.
