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.  We aim for “Good to Great” from the very beginning, and you can expect a good deal from the quality of our products always.
