Frequently Asked Questions

Will a performance muffler add horsepower to my vehicle?

Yes, performance mufflers typically add 2-10 horsepower by reducing exhaust backpressure and improving flow. The exact gains depend on your engine size, existing exhaust setup, and the muffler design. Larger engines like V8s see more noticeable gains. However, the primary benefit most owners notice is improved throttle response and a more aggressive exhaust note.

What's the difference between chambered, turbo, and straight-through performance mufflers?

Chambered mufflers use internal baffles to create a deep, tuned muscle-car sound with good drone control. Turbo mufflers use an S-tube path for quiet performance with minimal cabin noise. Straight-through (glasspack) mufflers have a perforated core for maximum flow and the loudest, most aggressive sound. Choose based on your sound preference and daily driving needs.

How do I choose the right performance muffler size for my vehicle?

Match the muffler inlet size to your existing exhaust pipe diameter. Most 4-cylinder and V6 vehicles use 2.25-2.5 inch pipes, while V8 trucks and performance cars typically use 2.5-3 inch. Measure your current exhaust pipe's outside diameter (OD) to find the correct fit. Going too large can actually reduce low-end torque.

Will a performance muffler cause drone on the highway?

Some performance mufflers can cause drone at certain RPMs, particularly straight-through designs on vehicles that cruise at steady highway speeds. To minimize drone, choose chambered or turbo-style mufflers, look for 'low drone' product notes, consider adding a resonator, or select a larger muffler case size which helps dampen problematic frequencies.

Do I need a tune after installing a performance muffler?

For most vehicles, installing just a performance muffler does not require a tune. The engine's ECU can adapt to the small change in exhaust flow. However, if you're also changing headers, catalytic converters, or adding forced induction, a tune is recommended to optimize performance and prevent check engine lights.
