A straight pipe is an exhaust system without a catalytic converter or muffler. It gets its name because it’s essentially a “straight shot” from the exhaust manifold to the back of the vehicle. However, a downpipe connects the exhaust port (the opening where exhaust steam escapes) to the exhaust system’s start.
How long does it take for a downpipe to cool down?
It takes an exhaust at least 20 minutes to cool down enough to touch. Of course, if it is a hot day or if your car is overheating, it will take a little longer. Parts of your exhaust can get up to 1600℉, so it is really good that you are being careful!
