GlassPak Muffler Upgrade

GlassPak Muffler Upgrade

Upgrade your exhaust system with GlassPak mufflers for a loud, sharp, and unmistakably aggressive exhaust note. This option is designed for customers who want maximum sound with minimal restriction, delivering the raw tone commonly associated with vintage muscle cars, hot rods, and period-correct performance builds.

GlassPaks offer a straight-through design that prioritizes sound and flow over noise reduction.

What This Upgrade Delivers

  • Very loud and aggressive exhaust tone

  • Sharp, raspy sound under throttle with minimal muffling

  • Straight-through design for unrestricted exhaust flow

  • Aluminized steel construction for durability and long service life

  • Direct-fit integration with your Classic Exhaust Systems kit

Important Notice

  • Selecting this upgrade replaces the standard mufflers in your kit

  • This option is not recommended for customers seeking a quiet or refined exhaust

Why Choose GlassPak Mufflers?

Compatibility

  • Available only when purchasing a full exhaust system

  • Installed during fabrication for a seamless, ready-to-install setup

About This Kit — What to Expect

All of our exhaust systems are fabricated to Original Equipment Manufacturing (OEM) specifications, directly reflecting the standards used in the factories where your classic car was built.

 

Please note that our pipes may exhibit minor imperfections due to the fabrication process, and they are intended for standard local car show quality.

 

All of our tubing is conventionally bent using a compression bending method, similar to factory specifications. We do not utilize the mandrel bending process in our fabrication. We always recommend professional installation of your exhaust system as minor adjustments to the pipes may be necessary, to ensure proper fitment.

 

Our systems are designed for the general consumer and weekend enthusiasts. However, if your vehicle is a numbers-matching, High End show-quality car and or date-coded mufflers, we advise against purchasing this system, as it may not meet your specific requirements.
