The Benefits of Custom Exhaust Systems: Unlocking Sound and Performance at Select Speed Shop
When it comes to upgrading the performance of your vehicle, few modifications have as profound an impact as a custom exhaust system. Whether you’re looking to improve power, enhance the sound of your car, or fine-tune its overall performance, a well-crafted exhaust system is key. At Select Speed Shop in Lowell, MA, we specialize in creating high-performance, custom exhaust systems for all types of vehicles—from Porsches to Nissan GT-Rs to Mazda RX-7s. Our expert team is committed to delivering top-tier exhaust systems that meet your needs and elevate your car’s performance and sound to the next level.
In this blog, we’ll explore the benefits of a custom exhaust system, dive into popular setups for some iconic performance cars, and show you how Select Speed Shop can help you achieve your dream exhaust system.
Why Upgrade to a Custom Exhaust System?
A custom exhaust system isn’t just about making your car louder (though that’s a big part of the fun for many enthusiasts). The right exhaust system offers a range of performance benefits, including:
1. Increased Horsepower and Torque
One of the most significant advantages of a custom exhaust system is the improvement in engine performance. Stock exhaust systems, while sufficient for daily driving, tend to be restrictive, reducing the flow of exhaust gases from the engine. By installing a high-flow exhaust system, you can increase the flow of exhaust gases, which helps the engine breathe better. This translates into more horsepower and more torque, especially in turbocharged and naturally aspirated engines.
2. Enhanced Exhaust Sound
A custom exhaust system is also a great way to personalize your vehicle’s exhaust note. Depending on your setup, you can achieve anything from a throaty growl to a high-pitched scream. If you’re after a deep, aggressive tone like the one you hear in Porsche 911s or a banshee-like scream of an RX-7, a custom exhaust will give your car the personality and sound it deserves.
3. Improved Fuel Efficiency
By reducing the restrictions on your exhaust system, a high-flow setup allows your engine to expel exhaust gases more efficiently, which can actually improve fuel efficiency in certain situations. When the engine doesn’t have to work as hard to push out exhaust gases, it can focus more on producing power in a more efficient manner.
4. Weight Reduction
Custom exhaust systems are often lighter than stock systems, particularly if you opt for titanium, stainless steel, or aluminum materials. By replacing the heavy, stock exhaust with a lightweight system, you can reduce overall vehicle weight, improving acceleration, handling, and fuel efficiency—particularly important for track enthusiasts.
5. Better Engine Cooling
A high-performance exhaust system helps manage heat more effectively, which is crucial when pushing your engine to its limits. By improving airflow and reducing backpressure, a custom exhaust can help keep engine temperatures in check, especially during high-performance driving or track days.
Popular Custom Exhaust Setups at Select Speed Shop
At Select Speed Shop, we’ve had the privilege of working on a wide range of performance vehicles, each with its own unique exhaust needs. Whether you drive a precision-engineered Porsche, a legendary Nissan GT-R, or a rotary-powered Mazda RX-7, we know how to create a custom exhaust system that brings out the best in your car. Here are a few popular setups we’ve worked on:
1. Porsche 911 – Aggressive Yet Refined Sound
Porsches are known for their precision engineering and distinctive exhaust notes. When it comes to custom exhaust systems for Porsche 911s, we focus on balancing performance gains with the refined exhaust tone that Porsche owners love. One popular setup is a cat-back exhaust system that includes a custom muffler, resonators, and high-flow catalytic converters. This setup not only unlocks extra horsepower but also gives the 911 an aggressive yet refined sound, perfect for those who want a performance boost without sacrificing the iconic Porsche exhaust note.
Popular modification: Fabspeed Motorsport Exhaust with a custom tune for performance and a more aggressive sound.
Benefit: Increased horsepower, reduced backpressure, and a deeper, more commanding exhaust note.
2. Nissan GT-R – Unleashing Power and Aggression
The Nissan GT-R is a powerhouse, and to match its incredible performance, a custom exhaust system is a must. With its turbocharged inline-six engine, a custom exhaust system can significantly improve the GT-R’s power output and turbo response. We often recommend a full turbo-back exhaust system with a larger downpipe and high-flow catalytic converters. This setup minimizes turbo lag, increases exhaust flow, and creates a louder, more aggressive sound that suits the GT-R’s aggressive nature.
Popular modification: HKS Hi-Power Exhaust System with custom stainless steel piping and upgraded downpipes.
Benefit: Improved turbo spool, more power, and a menacing exhaust growl that turns heads on the street or track.
3. Mazda RX-7 – Embracing the Rotary Engine’s Unique Sound
The Mazda RX-7 is a car that truly comes alive when paired with a custom exhaust system. The rotary engine has a unique exhaust note, and with a custom exhaust, we can amplify that high-pitched, screaming wail that RX-7 owners love. A popular setup is a two-rotor exhaust system that includes lightweight piping, aftermarket headers, and a custom single or dual exhaust system to reduce weight and improve engine breathing.
Popular modification: Apexi N1 Exhaust or custom FD3S exhaust system designed to handle the rotary engine’s specific exhaust flow characteristics.
Benefit: Boosts exhaust flow for increased power while amplifying the rotary engine’s signature scream.
4. Subaru WRX STI – A Rumbling Boxer Sound with Performance Gains
The Subaru WRX STI is known for its turbocharged flat-four engine, often referred to as a “boxer engine” for its distinctive sound. A custom exhaust for the WRX STI typically focuses on enhancing both sound and performance. A cat-back exhaust system with a turbo-back setup can give the WRX a deeper, more aggressive rumble while improving turbo spool and exhaust flow.
Popular modification: Cobb Tuning SF Intake and Cat-Back Exhaust System, paired with a custom downpipe.
Benefit: Increased horsepower, faster turbo response, and a throaty exhaust note that’s perfect for rally-inspired driving.
5. Honda Civic Type R – High-Revving and High Performance
For performance-focused drivers, the Honda Civic Type R is a favorite due to its rev-happy K-series engine. Custom exhausts for the Civic Type R are all about maximizing the engine’s potential and increasing exhaust flow for higher rpm levels. A 3-inch exhaust system or titanium exhaust setup can help extract every ounce of power while producing a crisp, high-pitched exhaust note that screams through the rev range.
Popular modification: Tomei Expreme Ti Exhaust or Greddy Spectrum Elite.
Benefit: Maximum airflow for top-end power and a distinctive, high-pitched exhaust sound.
