Exhaust Related FAQs


What is a rough idle?

A rough idle describes a vehicle's engine with spark plugs that are not firing correctly when the vehicle is in park, with no gas applied. Most vehicles idle between 600 and 1,200 RPM and should hold their idle speed consistently.

Can you put any exhaust on any car?

Not every exhaust will fit every car. Compatibility isn't just about car make and model; engine specs, optional extras, and even trim levels can influence the fit. Make sure you consider not just the make and model, but also engine details, fancy extras, and even trim levels before getting your heart set on a shiny new system.

Why is smoke coming out of my tailpipe?

The most common reason for thick smoke coming out of your car's exhaust pipe is the fuel to air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This is caused by a cracked or leaking fuel injector, a failing O2 sensor, or air filter that needs replacing.

Catalytic Converter FAQs


Can I drive with the catalytic converter light on?

A bad catalytic converter can increase your car's exhaust emissions, but it does not prevent you from driving. At Impact Auto we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Williamsburg, Newport News, Hampton and Virginia Beach. Exhaust gases will not escape easily and create an increase in exhaust gas pressure. The buildup in pressure can lead to high-cost repair bills in the future.

What can cause a catalytic converter light to come on?

A catalytic converter helps reduce harmful engine emissions from entering the air by breaking down the harmful byproduct of internal combustion into less-harmful compounds. If your catalytic converter isn't working properly the check engine light will come on. The most common causes for a catalytic convert warning light to display are a clogged, cracked or melted converter. Sometimes the problem isn't the catalytic converter at all but an exhaust leak letting gases out of the system before it reaches the converter.

What happens to your car after the catalytic converter gets taken?

Removing the catalytic converter has a dramatic impact on your vehicle's acoustics. A deep, loud roar replaces the engine's usual hum, intensifying as you accelerate. Additionally, expect rough transitions and sputtering sounds when shifting gears, indicating impaired performance and potential engine damage.

What Our Customers Are Saying

Amazing experience. I was visiting family and needed to get something checked out quickly. Marley was incredibly approachable, knowledgeable and willing to help when we couldn't find any other shop who would on short notice. If I still lived in town I'd make them my home shop! Highly recommend.

I called to make an appointment and when I described the issue they told me over the phone how to fix it myself. (It was apparently super easy). Other shops have charged me for the same issue in the past. This place did not. THANK YOU FOR YOUR HONESTY!!

Incredibly pleased. My husband recently inherited a 14 year old car from his grandmother that only had 47k miles on it. Needless to say, we figured it might need some work after being driven so little the last few years. Impact gave us an appointment for the same week I called, had a very friendly and knowledgable front desk staff, excellent mechanics who did the work, and didn't try and nickel and dime or talk us into needless repairs. They told us in order of what needed to be done the most and then did it the same day once we agreed. Couldn't be happier and would highly recommend them!
