How To Find An Exhaust Leak With Smoke Machine

In this video I demonstrate how to find an exhaust leak on an automobile using a smoke machine. Using a smoke machine is one of the fastest, easiest and most accurate ways of finding an exhaust leak. In the video I literally find my exhaust leak in under 5 minutes using a smoke machine. My leak was coming from a hole in the side of my muffler. However, an exhaust leak can exist at any given point along the entirety of the exhaust system including manifolds, gaskets, flanges, unions, resonators, flex pipes, etc. etc..

(By the way... I know, I know... I didn't need a smoke machine to find this leak. I've actually known about this leak for a few years now. It's a demonstration video folks. Hope it helps)

Note: The exhaust system shown in the video was a "single" exhaust system. Vehicles equipped with a "dual" exhaust system may require that each exhaust system be tested separately. If the "dual" exhaust system is equipped with an H-pipe or some other means of unifying both systems then the outlet that does not have the adapter hooked up to it will need to be capped off.

Also, as mentioned, some things that are a part of the exhaust system can leak and it can be normal for them to leak. I only mentioned a few things in the video. It is possible that other components not mentioned have "normal" leaks as well.
