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.
