by

The 6.2 Hellcat engine is renowned for its power and performance, and aftermarket exhaust systems from brands like Borla and AAC can enhance its sound and efficiency. However, like any performance modification, these exhausts can come with their own set of challenges. In this article, we will explore common problems associated with 6.2 Hellcat aftermarket exhausts and provide practical fixes.

Common Problems with Aftermarket Exhausts

  • Exhaust Leaks
  • Excessive Noise
  • Check Engine Light Activation
  • Improper Fitment
  • Drone at Certain RPMs
  • Corrosion and Rust

Exhaust Leaks

Exhaust leaks can occur at the joints or connections of the aftermarket system. This can lead to a loss of power and an unpleasant sound.

Fixes for Exhaust Leaks

  • Inspect all joints and connections for signs of leakage.
  • Tighten bolts and clamps to ensure a secure fit.
  • Use exhaust sealant or tape as needed to seal small gaps.

Excessive Noise

While aftermarket exhausts are designed to enhance sound, some users may find the noise level to be uncomfortably high.

Fixes for Excessive Noise

  • Consider adding a resonator to reduce sound levels.
  • Check for any loose components that may amplify noise.
  • Evaluate the type of muffler used and consider a quieter option if necessary.

Check Engine Light Activation

Installing an aftermarket exhaust may trigger the check engine light due to changes in exhaust flow and emissions readings.

Fixes for Check Engine Light Activation

  • Use an OBD-II scanner to diagnose the specific error code.
  • Ensure that all sensors are properly connected and functioning.
  • Consider a tune or a performance chip to recalibrate the engine settings.

Improper Fitment

Aftermarket exhaust systems may not fit perfectly, leading to alignment issues and potential damage to other components.

Fixes for Improper Fitment

  • Carefully compare the aftermarket system with OEM parts for compatibility.
  • Use adjustable hangers to achieve the correct alignment.
  • Consult with a professional installer if necessary.

Drone at Certain RPMs

Some drivers may experience drone, a low-frequency noise that can be bothersome at specific RPMs.

Fixes for Drone Issues

  • Experiment with different muffler designs to reduce drone.
  • Install a resonator to help mitigate low-frequency noise.
  • Change driving habits to avoid RPM ranges that produce drone.

Corrosion and Rust

Aftermarket exhaust systems may be more susceptible to corrosion, especially if not made from high-quality materials.

Fixes for Corrosion and Rust

  • Regularly inspect the exhaust for signs of rust and corrosion.
  • Apply high-temperature paint or rust inhibitor to exposed areas.
  • Consider upgrading to a stainless steel exhaust system for better durability.

In conclusion, while aftermarket exhaust systems for the 6.2 Hellcat can greatly enhance performance and sound, they can also present challenges. By being aware of common issues and their solutions, you can ensure a smoother experience with your Hellcat exhaust.
