Thinking about upgrading your car’s exhaust system? Whether you’re aiming for better performance, a throatier sound, or just something that sets your ride apart, a modified exhaust is a popular place to start.
But in Utah, where vehicle laws and emissions standards vary by city and county, it’s important to know what you’re getting into.
Let’s break down the pros and cons of aftermarket exhaust systems, specifically for drivers across Utah.
What Exactly Is an Exhaust System?
Before making upgrades to your vehicle, it’s important to understand what your exhaust system is and how it functions.
Think of your exhaust system as your car’s way of breathing out. It’s a series of pipes and parts that move engine fumes out and away from you and your passengers. Along the way, it quiets things down and cuts back on the stuff you don’t want in the air, like harmful emissions and loud engine noise.
The Pros of Aftermarket Exhaust
An aftermarket exhaust can change the way your car drives, sounds, and even feels. Here’s what makes it worth considering:
Better Performance
A well-designed aftermarket exhaust improves airflow, which means your engine doesn’t have to work as hard. The result? A noticeable boost in horsepower and torque. You may feel the difference on I-15 or climbing through Provo Canyon — your car just breathes better.
Fuel Efficiency
With improved airflow, your engine can run more efficiently. While the fuel savings may not be dramatic, many Utah drivers report modest improvements, especially on longer highway drives between cities like Logan and Salt Lake.
Sound Customization
Want your car to growl, roar, or hum? Aftermarket exhausts come with different sound profiles — from aggressive to refined. It’s one way to make your daily driver feel like something special.
Style Points
Let’s be honest, there’s just something about a polished set of dual tips. Whether you’re cruising through downtown SLC or even just pulling into a Logan grocery store parking lot, a modified exhaust turns heads.
The Cons of Aftermarket Exhaust
While the perks are real, there are a few trade-offs to think about before diving into an exhaust mod.
Legal Limits in Utah
Utah exhaust laws vary by area. Salt Lake County, for example, has stricter emissions testing compared to places like Tooele or Brigham City. If your modified exhaust changes emissions or pushes noise limits, you might run into inspection issues — or worse, a citation. Always check with your local guidelines or ask a professional.
Installation and Cost
Depending on the setup you want, exhaust modification can be an investment. Custom systems require precise fitting, and poorly installed parts can rattle, leak, or even cause damage over time. That’s why it’s worth going with a shop that knows your car inside and out, especially in places with wide weather swings like Pocatello or Millcreek.
Potential for Drone
Some aftermarket systems produce a “drone” noise at specific RPMs, particularly at highway speeds. What sounds great in short bursts around Provo city center might get old on longer drives between Orem and Bountiful.
Know Before You Modify: Utah-Specific Notes
Utah is not one-size-fits-all when it comes to exhaust modification. Some key things to consider include:
- Downtown Salt Lake City and South Salt Lake have stricter noise and emissions ordinances.
- Ogden, South Ogden, and Clearfield are a bit more lenient, but it still pays to be smart, especially during annual inspections.
- If you’re in Logan, you’ll have more flexibility, but a poorly installed system can still fail a safety check. Pocatello, Idaho, may also share some leniency similarities with its Utah counterparts, but always double-check.
- Live near West Valley or West Jordan? You’re probably commuting in heavier traffic a lot of the time (especially on Redwood). Opt for a performance-focused yet quieter system to enhance your daily drive experience.
