Frequently Asked Questions
Will an aftermarket exhaust void my Toyota warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your warranty simply because you installed an aftermarket exhaust. However, if the exhaust directly causes a powertrain issue, that specific repair may not be covered. Cat-back systems are the safest choice as they don't modify emissions equipment.
What's the difference between cat-back and axle-back exhaust?
A cat-back system replaces the entire exhaust from the catalytic converter to the tailpipe tips, providing the most significant sound and performance improvements. An axle-back system only replaces the section from the rear axle back, offering a more subtle sound change at a lower price point.
How much horsepower does an exhaust system add?
A cat-back exhaust system typically adds 5-15 horsepower on naturally aspirated Toyota engines. The bigger benefit is improved throttle response and a more satisfying exhaust note. Pairing an exhaust with a cold air intake and tune can yield more significant power gains.
