Quality Control

Every single unit is tested at least twice throughout the manufacturing cycle.

The first test is a visual inspection. The operator makes sure that:

• The part is placed in its fixture to ensure proper fitment on the vehicle.
• The welds are completed without any holes or gaps.
• The ends of the pipes are fished to the proper specifications.

The second test is a pressure test. The operator blocks all of the entrances and exits of the part and fills it with compressed air with a pressure equal to five times that of a standard exhaust system. This guarantees the structural integrity of the welds holding the piece together.

Please feel free to inquire, our engineers will give advice on all questions of sizes, functions, and materials chosen.
