10 Best Deep Sounding Muffler

The BORLA 400844 CrateMuffler is constructed with durable T-304 stainless steel, ensuring long-lasting corrosion resistance, which is beneficial for durability over time. Its all-welded construction and bolt-on installation make it relatively straightforward to fit, especially for Chevrolet Small Block V8 engines such as the 350, 383, or 406 CID.

Featuring 3-inch inlet/outlet sizing and a chambered internal design, the muffler delivers a deep, aggressive exhaust note typical of performance mufflers. Borla offers a “No Drone Guarantee,” which means the muffler is designed to minimize the low-frequency sound that can be uncomfortable during long drives. Measuring approximately 14” by 4.35” by 9.10”, it is somewhat larger than standard mufflers, so adequate space in the vehicle’s exhaust system layout is necessary.

This model is not universal and fits specific Chevrolet engines, providing a direct-fit approach that simplifies installation and ensures optimal performance for those vehicles. While the sound is robust yet controlled, making it ideal for those seeking a deeper tone without excessive noise, it may not suit other car models without modification. Weighing about 5.4 kg, it offers a good balance between sound quality, durability, and ease of installation for Chevy Small Block V8 owners looking for a performance upgrade.

The EVIL ENERGY muffler is a universal fit, straight-through design made from polished stainless steel, which helps it resist rust and vibrations. Its 2.5-inch inlet and larger 4-inch outlet allow for smoother exhaust flow, supporting a deeper, louder sound favored by many car enthusiasts. The muffler is packed with sound-absorbing cotton inside, producing a low, deep tone that enhances your car's presence without being overly harsh. Its two-layer stainless steel walls also reduce unwanted vibrations, contributing to a cleaner sound quality.

Installation is straightforward since it bolts on and fits a variety of cars, but you should measure your car’s inlet size before purchasing to ensure compatibility. The burnt blue tip adds a unique visual flair that can make your vehicle stand out. Being a universal muffler, it might not fit as perfectly as a direct-fit model made for your exact car, possibly requiring minor adjustments during installation. Some users who want a very aggressive or very quiet sound may find this muffler’s tone to be more moderate.

If you want a durable, visually appealing muffler that delivers a rich, deep exhaust sound and works with many cars, this is a solid choice.

The Borla 400493 Pro XS Muffler is made from durable T-304 stainless steel, ensuring resistance to rust and long-lasting reliability. Its oval, notched design with dual 2.5-inch inlet and outlet pipes fits many cars and trucks that accept this size, offering a direct-fit option which simplifies installation for compatible vehicles.

Weighing approximately 13 pounds, this muffler is a sturdy yet manageable component. Borla’s Pro XS line is known for enhancing exhaust flow and producing a deeper, more aggressive sound without being overly loud, making it a good choice for drivers seeking improved performance and a sportier exhaust note.

This muffler is well-suited for car and truck owners looking for a durable, performance-oriented exhaust upgrade with a deeper tone, especially if their vehicle matches the 2.5-inch dual inlet/outlet size.
