Loudest Cities in America: Where Exhaust Upgrades Roar

Few mods change your car's personality faster than an exhaust upgrade. To find out where America is turning up the volume, American Muscle analyzed internal sales data from 25 major cities, search trends for top exhaust-related keywords across 100 cities, and surveyed 1,001 drivers about their upgrade habits. See where drivers are spending the most, searching the hardest, and pushing the limits once the install is done.

Key Takeaways

• Tampa residents spend the most per exhaust upgrade order at $656 — that's 45% more than the lowest-performing city, Springfield ($452).
• Atlanta residents search for exhaust upgrades at 6x the rate of New Yorkers (1,409 vs 232 per 100K residents).
• 1 in 10 drivers have upgraded their exhaust, with performance and sound tied as the top motivations (59% each).
• Americans who upgraded their exhaust are nearly 2x more likely to speed 20+ mph over the limit.

Where Exhaust Buyers Spend the Most

Some cities don't just love loud, they're willing to pay for it. Looking at transaction value reveals which markets invest the most per exhaust upgrade.

• Tampa tops the list with an average exhaust order value of $656, outspending the lowest-ranked city, Springfield, by $204 or 45%.
• San Antonio captured the largest share of exhaust orders at 8.6%, but ranked sixth in average order value.
• Houston followed a similar pattern, ranking second in total volume at 7.4% while landing near the bottom in per-order spending.

Cities Searching Loudest for Exhaust Mods

Search behavior tells another part of the story. When drivers are serious about upgrades, it often starts online.

• Atlanta dominates exhaust-related search interest, logging 1,409 searches per 100,000 residents — 6x higher than New York City's 232.
• Florida is a hotspot: Orlando ranks second and Miami third, suggesting statewide momentum for exhaust upgrades driven by car culture, cruising, and year-round driving weather.
• New York City ranks last in per capita exhaust search interest. Dense urban driving conditions and stricter noise enforcement likely keep exhaust curiosity quieter.

Why Drivers Go Loud, and What Comes With It

Behind every exhaust upgrade is a driver chasing something specific, whether it's power, sound, or attention.

• 1 in 10 surveyed drivers have upgraded their exhaust system, most often for improved performance (59%), sound (59%), and aesthetics (25%).
• 64% of exhaust upgraders admit they rev their engine to show off their sound.
• Drivers with exhaust upgrades are nearly twice as likely to exceed the speed limit by more than 20 mph (33% vs. 18%).
• 23% of upgraders have faced consequences tied directly to their exhaust mods, including tickets, fines, or noise complaints.

Methodology

This study draws on the following three data sources:

1. Internal American Muscle sales data: comprising exhaust order volume and average transaction value across 25 U.S. cities for 2024–2025
2. Search volume data: tracking monthly searches for six exhaust-related keywords (e.g., "muffler delete," "performance exhaust") across 100 U.S. cities from 2024–2025, normalized by population using U.S. Census Bureau estimates
3. A national survey of 1,001 U.S. drivers: conducted to understand exhaust modification behaviors, motivations, and driving habits; survey findings related to exhaust upgraders based on the 10% of respondents who reported modifying their vehicle's exhaust system
