How to legally boost your ride's volume
Want to make your presence known from miles away? Look no further! Whether you're aiming to enhance your car's natural rumble or give it the growl of a high-end sports car, we've got all the modifications to make your vehicle roar. While loud cars are attention-grabbing, be sure to check local regulations and consider your neighbors. If you're still keen on elevating your ride, read on to craft the car of your dreams.
Key Points to Note
- Drilling small holes in your exhaust pipes is a legal method to increase your car's volume – it's a safer alternative to removing the muffler.
- Polishing and cleaning your exhaust pipes can enhance the sound of your exhaust system.
- Upgrade to a dual exhaust cat-back system to add horsepower to your car and produce a powerful roar.
Steps to Follow
Enhance your exhaust pipes with drilled holes.
Drilling holes in the exhaust system enables more sound waves to escape. Utilize a 0.38 inch (0.95 cm) cobalt drill bit to create 6-8 small perforations on the pipe situated between the muffler and catalytic converter. These perforations allow sound waves to exit prior to reaching the muffler, resulting in a more aggressive car sound.
- Ensure these holes are drilled downstream of the catalytic converter to convert exhaust fumes into non-toxic emissions. Failure to do so may lead to harmful gases entering your vehicle cabin.
- If you're unsatisfied with the sound, additional holes can be drilled or experimenting with a larger drill bit is an option.
Revitalize your exhaust pipes.
Eliminate sound-dampening carbon deposits from your exhaust pipes. Accumulated debris within the exhaust system diminishes both engine performance and sound quality. Purge the buildup by washing the pipes with soap and water, followed by application of degreaser. Employ steel wool to scrub off the residue, and finish by applying metal polish to the exhaust tips.
- Alternatively, opt for a carbon cleaning service to elevate your vehicle's sound. Costs for professional treatment vary from $125 to $325, depending on your vehicle and engine type.
Install an aftermarket exhaust tip.
Enhance your car's sound with an exhaust tip attached to your tailpipe. Whether you desire a subtle purr or a fierce roar, these small yet powerful components enable you to customize and amplify your vehicle's volume. Opt for a larger tip for a deep, robust sound, or go for a smaller one for a more aggressive rasp.
- Exhaust tips range from $25-150, depending on material quality.
- Many auto enthusiasts prefer double-walled exhaust tips for a richer sound compared to single-walled ones.
Upgrade your muffler.
Choose a straight-through muffler for optimal sound. This muffler type facilitates easy exit of exhaust gases and sound waves, enhancing both volume and efficiency of your vehicle. Experiment with muffler placement to achieve desired sound: while most are positioned near the rear, moving it closer to the engine yields an even louder roar.
- Avoid s-type mufflers with many baffles as they tend to absorb sound.
- Replacing a muffler typically costs $160-240 on average.
Eliminate your resonator.
Decrease muffler effectiveness with a resonator delete. Similar to a muffler, the resonator minimizes engine noise by absorbing sound. Typically filled with sound-absorbing material, the resonator is connected directly to the exhaust system. Removing it reduces muffler efficiency, forcing it to dampen more of the engine's raw sound.
- A resonator delete transforms your vehicle's sound to a deep, smooth roar.
- Professional resonator deletion costs $100-220 depending on your car's make and model.
Opt for larger exhaust pipes.
Upgrade to larger exhaust pipes by 0.5 inch (1.27 cm) for a significant roar. The exhaust system encompasses vital components like exhaust pipes, muffler, and resonator, contributing majorly to your vehicle's sound. Switching to bigger pipes enhances gas flow and facilitates easier sound exit.
- To avoid excessive back pressure, limit pipe size increase to 0.5 inch (1.27 cm) to 1 inch (2.54 cm).
- Replacing exhaust pipes, including parts and labor, typically costs $835-860, depending on your vehicle make and model.
Go for a straight-pipe exhaust conversion.
Swap your muffler for a loud straight-pipe exhaust. This alteration involves replacing the catalytic converter, resonator, and muffler with a single straight tube. The design of the tube facilitates easier sound transmission, with some systems producing over 120 decibels.
- Driving without a catalytic converter violates noise and emission regulations in most states. Verify local laws to avoid fines.
- Professional straight-pipe installation costs around $1500 on average, while DIY replacement ranges from $75-200, depending on your car and skills.
Upgrade to a cat-back exhaust system.
Opt for a dual exhaust cat-back system to enhance torque and volume. This modification alleviates pressure on your engine, enhancing airflow and sound. Dual exhausts produce the most aggressive noise, but if you're on a budget, consider a single exhaust cat-back system–light, affordable, yet still roaring.
- Stainless-steel cat-back exhaust systems typically range from $150-400, while there are more budget-friendly aluminum versions.
Upgrade with a turbocharger.
Enhance combustion sounds with a turbocharger. By increasing airflow into the engine's cylinder, a turbocharger boosts overall performance and power. For a louder sound, pair it with a cold-air intake; colder air contains more oxygen, resulting in larger combustion in the engine.
- Alternatively, add a turbo whistle to your exhaust pipe for a similar effect as a turbocharger.
- Turbochargers typically range from $500-5000, depending on your vehicle's make and model.
- Cold-air intakes usually cost between $30-100.
Run your car with open headers.
Remove your entire exhaust system for an intensely loud ride. This method involves eliminating the muffler, exhaust pipe, and catalytic convertor. With easier exhaust gas exit, open headers significantly boost horsepower and sound.
- With open headers and a larger engine (e.g., V6 or V8), your car might even produce flames when revving to higher RPMs.
- For proper open header operation, visit a shop for tuning, with prices typically ranging from $200-500, depending on the extent of tuning needed.
- Due to their loud noise and emissions, open headers aren't legal in most states, so verify local laws to avoid fines.
Enhance your engine.
Switch to a V6 or V8 engine for a powerful, resonating sound. More cylinders mean more power and noise. V engines, unlike inline ones, pack cylinders densely, often found in high-performance sports cars.
- For a smoother exhaust sound, opt for an inline engine. Inline-4s are common, so upgrading to an inline-6 increases noise.
- Engine replacement is costly and time-consuming, so it's not a common approach.
- A new V8 engine can cost around $7000 (excluding labor), so consider your car's age; if it's older, buying a new vehicle might be wiser.
Install engine-enhancing speakers.
Amplify intake and engine noises with an exhaust microphone. Some specialty shops attach ceramic microphones to exhaust pipes, boosting vehicle volume. They may even add music to mimic these noises for extra roar.
- Some can distinguish between fake and authentic sounds, so if you prioritize sound quality and authenticity, avoid this method.
Helpful Hints
Important Cautions
- While removing a muffler is a popular method to increase car noise, it's illegal in all 50 states. Additionally, it may void your warranty if it damages other parts of your car's emissions system.
- Each state has its own regulations concerning exhaust modifications, so ensure to review local laws for potential restrictions. Violating regulations could result in fines ranging from $25-500.
- Vehicle modifications can pose risks, so always prioritize safety: wear protective gear like safety glasses and gloves while working, and ensure the vehicle is stationary with the brakes engaged.
