- Borla's T-304 stainless steel construction enhances sound resonance and durability.
- You can achieve aggressive volume without the annoyance of highway drone.
If you drive a V8-powered GMC Sierra or Chevy Silverado, you likely have one complaint: it's too quiet. From the factory, manufacturers stifle the natural roar of the engine to appeal to the average commuter. But for truck enthusiasts, the goal is often finding that signature American V8 rumble.
If you are searching for how to make your truck exhaust sound deeper, you are in the right place. Here are the most frequently asked questions about unlocking the true voice of your truck.
What Actually Makes a Truck Exhaust Sound Deeper?
Creating a deeper tone isn't just about removing parts, it's about engineering the flow of sound waves. A deeper tone is achieved through three main changes:
Increased Pipe Diameter
Larger pipes allow exhaust pulses to expand, which lowers the frequency of the sound waves, creating a deeper "baritone" note compared to the higher-pitched "tenor" of stock pipes.
Straight-Through Muffler Design
Factory mufflers use baffles and chambers that trap sound and create backpressure. A high-performance Cat-Back Exhaust System typically uses straight-through, perforated cores that let sound pass through while absorbing high-frequency rasp, leaving the deep power notes.
Material Quality
The metal matters. Thin, cheap steel can sound "tinny." T-304 stainless steel has denser acoustic properties that help resonate a fuller sound.
What Are My Options for a GMC Sierra or Silverado Exhaust Upgrade?
Since the Sierra and Silverado share the same platform, the upgrade paths are similar. If you're looking for a specific Sierra exhaust, the most direct approach is a full system replacement to maximize that deeper tone.
Borla offers three sound levels for these trucks:
- Touring: The deepest, smoothest growl. Removes the stock whisper without being overly aggressive.
- S-Type: A deep, throaty roar that opens up significantly under throttle.
- ATAK®: The loudest option, still engineered to maintain a deep, non-distorted tone.

Can I Hear the Difference Between These Sound Levels?
Describing sound is difficult, but hearing it makes the choice easy. Watch this video comparison to hear how a Borla system changes the character of the GM truck platform:
Will Making My Exhaust Deeper Cause Drone?
This is the most common fear for truck owners. Drone is that persistent, vibrating hum that fills the cabin at highway speeds, usually around 1,800–2,000 RPM.
Many budget exhaust kits achieve a "deep" sound simply by removing mufflers, which almost always results in drone. Borla systems are built differently: No Drone technology is engineered into the internal architecture of every muffler to cancel out the specific frequencies responsible for drone, so you get the deep, aggressive exterior sound without losing a cabin quiet enough for a conversation or a phone call.
Does a Performance Exhaust Withstand Off-Road Abuse?
If you use your truck like a truck, durability is the real question. A deep-sounding exhaust isn't worth much if it doesn't hold up.
Borla systems are built from T-304 austenitic stainless steel, inside and out, a different class of material than the aluminized steel used on most factory systems. Whether you're towing or heading off-grid, the exhaust is built for the heat and the elements.

Is Installation a Difficult DIY Project?
Borla systems are designed as a direct bolt-on upgrade, making Silverado or Sierra exhaust installation a straightforward job for the driveway mechanic. Unlike universal kits that require welding, Borla systems use precise mandrel bends that align with factory hanger locations. With basic hand tools, most wheelbase configurations can be completed without cutting or welding.
