How to make your exhaust loud

how to make your exhaust loud

When it comes to driving, you want your exhaust to be loud.  You want to hear that distinctive roar from your engine as you speed down the road. You started modifying your car because you wanted more power and now you’re getting it, but how do you make sure everyone around knows it?

In this article we’ll tell you everything there is to know about making your exhaust system as loud as possible for maximum performance gains. Just follow these three guidelines.

1) Upgrade Your Exhaust – You’ll get a big increase in noise by simply installing a new aftermarket exhaust, especially if yours is stock. This will be obvious right away and give a great kick of satisfaction when driving your car for the first time with the new exhaust. But  you can do more.

2) Use a High Flow Catalytic Converter – The catalytic converter is designed to reduce noise coming from the exhaust by forcing unwanted gases through a series of catalyzed reactions that break down harmful pollutants into less noxious elements. However, this process makes your car very quiet and reduces performance. It also doesn’t work if you don’t have one. Plugging off your cat will make your car loud, but it’s highly illegal and could land you in court with stiff fines if caught.

3) Remove Your Exhaust Restriction or Install Straight Pipes – This is usually done at the shop when an aftermarket performance exhaust system is installed, but it can be done easily enough on most cars at home. Removing the rear catalytic converter and replacing it with straight pipes will result in a significant increase in volume, but you’ll have to consider that your car will emit higher levels of poisonous gases into the atmosphere.

4)  Test Drive Your Car – This last tip is something you can do yourself. Just get in the car, drive it around for a bit and see if there’s any difference in noise level.

These are all great ways to make your car louder, but they are not the end of the road. There are plenty more options to explore that will help you take your system to maximum volume potential. We recommend checking out this guide on how to build an exhaust pipe . It’s packed with tips and tricks for increasing power while also making your ride noticeably louder. You’ll be proud of it when cruising down the street or carving up country roads. That being said remember that too much loudness is not enough so enjoy your new setup!

5)  Get an aftermarket muffler – This is the simplest and easiest way to get your car sounding great. Just pick out one that sounds good to you and install it on your existing system. We recommend getting a straight through design because it enhances the sound quality of your engine and gives you a deeper bass than most stock mufflers.

6) Install dual exhaust – Dual exhaust means more back pressure which means louder noise so we know what you’re thinking, “dual exhausts are loud AF”. We agree but they’re also pretty pricey. Not only will they make your ride look like a muscle car (and be heard from miles), but they’ll add extra power as well by freeing up some air flow restrictions. Don’t think speakers can’t help you out either. They can be packed with wattage that will let your sound system go toe-to-toe with the best of them, but make sure to install high quality speakers because it’s all about quality over quantity here.

7)  Get a performance muffler – This is the next step in aftermarket exhausts. It does everything that dual exhaust can do except it’s usually easier to install and fits more vehicles. So you get all of the benefits without any of the drawbacks.

8)  Install header-back exhaust system – You guessed it, this is even louder than an aftermarket muffler but also costs quite a bit more so we only recommend this for dedicated car enthusiasts who enjoy loud cars.

9) Make your own system – We don’t recommend messing with this if you haven’t done anything like it before because it could damage your engine or set your cabin on fire (seriously). But if you’re willing to put in some hard work and effort then  go ahead and build your own exhaust system. It’s actually not as hard as it sounds and you don’t need to know a thing about engineering or welding. Just get a few tips from an expert then pick out some pipes that will fit your ride perfectly. We highly recommend going with a straight through design because they’re easy to construct and improve the sound of your engine by removing all air flow restrictions.

10) Remove catalytic converters – This is illegal in most states so we don’t recommend doing this if you value being able to drive freely everywhere without fear of being caught by police officers. But hey, if you have nothing to lose then go right ahead and get rid of those pesky catalytic converter(s). Your car will be a little louder, a little faster and emit lots of bad stuff into the air (but that’s not your concern).

11) Use stainless steel pipes – If you’re looking to build the loudest car in town then don’t even waste your time with mild steel pipes. Get some high quality stainless steel ones because they’re lighter, stronger and produce way less back pressure than their weaker counterparts. Just make sure you use high quality welds when assembling them or they could rust out over time. Stainless steel isn’t cheap but it’s worth every penny because it will give you maximum performance without sacrificing durability .

12) Buy an aftermarket H pipe crossover – This is basically two Y-shaped exhaust pipes combined into one so having an extra one underneath your car’s undercarriage won’t hurt. It’ll make your ride sound deeper and more aggressive, plus it costs a lot less than installing two Y-shaped exhaust pipes because you only need one for this to work properly.

13) Install aftermarket headers – Made from high quality stainless steel, these will last a lifetime if installed correctly and without any air flow restrictions. Unlike H-pipe crossovers, headers don’t have that deep throaty sound but they’re better at producing mid to low end frequencies which makes them ideal for revving out . They also reduce back pressure which lets the engine breathe easier and perform better in the long run.

14)  Use circular saw blades as mufflers – It may look like something a mad scientist would come up with but a circular saw muffler will reduce back pressure by improving the airflow coming from your engine’s exhaust manifold. They do make aftermarket ones but if you have a lot of circular saw blades lying around then those can be used too. Just cut out some cardboard to make a cone, drill some holes in it and mount it on your car’s muffler as an improvised aftermarket muffler.

15) Buy a new muffler – Replacing your stock muffler is the simplest way to sound more aggressive without having to use anything too crazy. Most cars come with cheap steel ones but high quality stainless steel ones are much better for improving performance while reducing back pressure at the same time . They’re also lighter and won’t rust out in a few years which makes them an excellent choice if you want something better, louder and more durable.


Car exhausts aren’t very complicated but they do affect the performance of your engine in a big way. If you want to get rid of back pressure, gain more horsepower and sound aggressive all at once then go with an aftermarket H-pipe crossover. But if you’re just looking to reduce back pressure then replace that stock muffler with something better like a stainless steel one. Either way, following these tips will take your car’s performance to the next level while sounding better than ever before.
