Car people and bike people sometimes overlap, and sometimes don't. And the same can also be said of mods for their vehicles. Take, for example, switching out your exhaust.
Assuming you live in a place where you can legally modify your vehicle (some places have more restrictions than others, so it's always a good idea to be up on what's allowed where you live), maybe you want more power. Maybe you want it to look better than the stock exhaust, and sound better, too. I mean, if the end result isn't going to be more appealing to you than what came on the bike (or car), why bother?
The question posed here by the guys at Brick House Builds is a simple one, on its face: Which motorcycle exhaust is best on BJ's Porsche 924S? Unlike so many people who might have similar questions, BHB is a motorcycle shop. So the good news is, they frequently have a few spare motorcycle exhausts lying around. That makes the job of comparing and contrasting them on the Porsche a much more attainable task than it might be for anyone who didn't want to shell out a bunch of extra money for three experimental exhausts.
So, for science, you should probably put on your headphones before you watch this video. You're going to want to hear how they all sound, aren't you? Of course you are!
In one corner, we have not one, not two, but THREE motorcycle exhausts from Two Brothers, Delkevic, and Yoshimura. And in the other, we have a Porsche 924S with an unfortunate rattle in its muffler. It's a nice example, but a shame about that rattle.
Sure enough, when BJ takes the old exhaust off and shakes it out, we see exactly why it's making the noise that it is. The debris that pours out of it is big and chunky, and there may even be enough of it to register a weight on a scale if you put it in a cup.
Motorcycle exhausts are typically smaller than car exhausts, which seems totally logical since motorcycle engines (and motorcycles in general) are much smaller vehicles. Plus, bike exhausts, like car exhausts, are typically supplied from manufacturers to fit specific applications.
That doesn't mean you can't make an exhaust meant to fit one bike fit another instead; it just means you're going to have to put in a little bit of extra work. And the same is true with cars. You can make it happen if you really want to, but you'll probably have to do some welding and/or fabrication to get the two things to work together.
Luckily, this is BHB, and that's what they do. So, in the interest of science, that's exactly what they did here. Don't worry, you get a nice, well-miked recording of a short, spirited test ride with each exhaust installed in turn. There's a clear winner, but the one thing this video can't adequately express to those of us not in the car is how loud each exhaust actually sounds in the cabin.
And that's a significant concern. You want a good sound, and you don't want it to be too quiet. But you also usually don't want it to be so loud that everyone in your neighborhood hates you when you drive somewhere at 2 a.m.
