Both the C7 Corvette and the Supra A90 benefit greatly from aftermarket exhaust upgrades. The goal is usually to amplify the car’s inherent sonic qualities and make them more pronounced, exciting, and personal. It’s important to understand the basic types of exhaust modifications available.

Common Exhaust Upgrade Types

When looking to change your car’s exhaust sound, you’ll encounter a few main types of systems:

Axle-Back Exhaust: This is the simplest and often most affordable upgrade. It replaces the mufflers and tips at the very rear of the exhaust system. It will change the tone and volume but has a less dramatic effect than full systems.
Cat-Back Exhaust System: This is a more comprehensive upgrade that replaces everything from the catalytic converter(s) back. This includes the mid-pipe(s), resonator(s), mufflers, and tips. Cat-back systems offer a significant change in both sound and often performance.
Header/Exhaust Manifold Upgrade: For maximum sound alteration and performance gains, headers (or aftermarket exhaust manifolds) replace the restrictive factory manifolds. This can make the exhaust note much louder and more aggressive, but it’s a more involved installation and can sometimes affect emissions compliance depending on the material and whether catalytic converters are integrated.
Muffler Delete/Resonator Delete: This involves removing specific components from the factory exhaust. A muffler delete makes the exhaust very loud, while a resonator delete can change the pitch and reduce drone. These are often DIY-friendly but can sometimes lead to undesirable sounds or excessive loudness.

Choosing the Right System for Your C7 Corvette

For the C7 Corvette, the choice largely depends on how loud and aggressive you want to go. If you love the V8 rumble and want to hear it more clearly, an axle-back or cat-back system from a reputable brand like Borla, Corsa, or MagnaFlow will likely be an excellent choice. These often offer different sound profiles, from mellow performance to wide-open race car loudness. Many systems offer valve control, allowing you to switch between quiet and loud modes – a great option for daily driving.

When choosing, consider looking for systems that are:

Material: Stainless steel (like 304 or 409) is durable and resists corrosion.
Design: Performance-oriented designs often use larger pipes, straight-through mufflers, and optimized routing.
Drone: Pay attention to reviews regarding cabin noise at constant highway speeds (drone). Some systems are better at eliminating this than others, thanks to specific tuning or resonators.

Choosing the Right System for Your Toyota Supra A90

For the Supra A90, the goal is often to inject more life and aggression into the inline-six’s natural sound. Many owners find the stock exhaust too quiet relative to the car’s performance. Aftermarket cat-back systems are extremely popular for the Supra, offering a noticeable increase in volume and a sportier tone. Brands like Akrapovič, Remus, and Fi Exhaust are well-regarded, often providing systems with integrated exhaust valves for adjustable sound levels.

When selecting for a Supra, think about:

Tone: Do you prefer a sharper, higher-pitched bark or a deeper, more muscular growl from the inline-six?
Volume: How much louder do you want it to be? Is it for occasional spirited drives or a constant presence?
Drone Reduction: Inline-six engines can sometimes be prone to drone when modified. Look for systems that specifically address this or offer valve control to mitigate it.
Material & Finish: Carbon fiber tips or specific finishes can add to the aesthetic appeal alongside the sound.
