How do I know which way to install this muffler?

The muffler is directional, meaning it's tuned to flow in a specific direction for optimal sound and drone reduction. You can identify the outlet end by the mounting bracket welded to the endcap.

What is the difference between the S-Type and Touring sound levels?

The S-Type muffler offers a more aggressive and louder exhaust note. To achieve the quieter Touring sound level, you can add the Borla 400938 resonator to this muffler.

What makes T-304 stainless steel better than T-400 series?

T-304 stainless steel is a well-built material that offers superior corrosion resistance and durability compared to T-400 series stainless steel, ensuring a longer lifespan for your exhaust system.

About this part

Product Details

Built from T-304 stainless steel, this Borla CrateMuffler is designed to optimize sound and power for crate and custom-built LS3 engines. The directional flow design, identified by a mounting bracket on the outlet endcap, is tuned specifically for engine families like the Chevrolet LS3 6.2L V8 found in applications such as the Camaro, Corvette, SS, and Pontiac G8. This careful tuning helps to dramatically reduce or eliminate exhaust drone, making your driving experience more comfortable.

Borla uses T-304 stainless steel, which is a stronger material than T-400 series stainless steel, offering better performance and long-term durability. The muffler's construction is precise, ensuring it fits right where it's supposed to. This S-Type version offers a more aggressive sound profile compared to Borla's Touring level, which can be achieved by adding their 400938 resonator.
