observation from listening to exhaust vids vs real life

Hey everyone, I recently bought a 1993 F150 and I've been listening to a lot of exhaust clips on YouTube which can get frustrating and it reminded me of when I was doing the same thing for my Mustang and I realized something. Maybe this will help you out when deciding on what something "sounds like". I remember hearing some GT500 muffler videos and thinking it sounded pretty loud but everyone was saying they are too quiet. Well, same thing w/ the F150 clips. I heard a couple that people say their exhaust is quiet when to me it sounded kinda loud. Here's the thing, if they put the mic,camcorder, go pro etc right behind to next to the tail pipe it's going to sound much louder than if you were standing 10 feet from it or if it was driving by. I know that seems obvious, but if you are watching exhaust videos and the exhaust itself it's hitting the mic, forget about it, no way that is a good representation of what it sounds like. I've learned to ONLY pay attention to the ones that are pretty far away from the mic or a drive by is even better.

Anyways, that's all and hopefully this helps someone out who's out there listening to exhaust videos trying to figure out what sounds best. Thanks for reading

It's very difficult to record accurate exhaust sounds. If the mike gets too close, you'll hear the 'wind' of the exhaust, and too far, you don't get much sound at all.

People have to keep in mind, too, that we're all limited by our sound cars and speakers. Most computers are NOT set up for fantastic sound quality, so often we end up with no bass tones, etc.

A few of my cars have been recorded for exhaust promo/tech videos, and even taking a dvd and putting it in my surround-sound system, none sounded anything like they do in reality.

Another issue is that many people record their vehicles in neutral, revving the engine. That is the WORST an engine will sound! They all sound far better when under load. The best method that I've seen is taping a high quality mike to the rear bumper between the tips and then driving the car. Ideally you won't get road/wind noise, but you will get the actual exhaust sound.

I've been lazy and haven't put up my new exhaust vid, but I recorded a before and after. For each portion I placed my mic right next to the exhaust, but also walked away to about 50 ft. The reasoning behind that was to give some sort of visual cue to how far away you can hear this exhaust. Which hopefully translates to a somewhat reliable way to interpret the loudness of the exhaust. Honestly maybe I'll put up a dB meter, I think the best way to measure is to actually show the people what dB it's at.

Videos do a horrible job at portraying sound, unless you have some amazing and expensive recording hardware and software. As an example, I'm glad AM has a lot of videos for most of their exhausts, but I can't really trust any of them. They all seem to be the same in loudness, and the only audible things I really can decipher are how many burps or gurgles does the exhaust get me.

The best comparisons are when people compare to stock. I think it's the best bet at getting something kinda accurate, because more than likely the person listening has your car and is stock and is also looking for an upgrade. Otherwise it's still kind of a crapshoot.

You also have to be aware of your proximity to things that can absorb/reflect the sound. You have to find a piece of road with no foliage or buildings. I've seen guys make videos while the car was in a garage, next to a building, in a car wash stall, and all kinds of other stupid places, and it makes it impossible to determine what the exhaust really sounds like. Add to that the varying quality of microphones, and how your own viewing device is configured, and you quickly realize you actually have to lay ears on a given exhauist to get a true notion of it's sound.

Chasing exhaust is a pain in the ass, and I've come to the conclusion that the only place it matters is in the cockpit.

Yeah very true on the revving in neutral thing JBT. Most people do that but it's not what it sounds like under load at all. Plus these videos on these older F150s is usually younger kids so when something is "too quiet" watch out, it's probably pretty loud just doesn't rattle windows so it's "quiet" lol

I'm very grateful for the videos, they helped me tremendously deciding on the sound I was looking for!
