Features
Exhaust flexible pipe has interlock liner recommended for forced induction applications.
- Isolate vibration generated by engine; thereby relieve stress on the exhaust system.
- Reduce premature cracking of manifolds and downpipes and help extend the life of other components.
- Applicable to different positions of exhaust system. Most effective when installed in front of the pipe section of exhaust system
- Double wall stainless steel for ensuring durability .Technically gas- tight
- Made of high temperature resistant & highly corrosion resistant material
- Available in all standard sizes & of any stainless steel material
- Compensate for the mis-alignment of exhaust pipes.
Quality Control
Every-single unit is tested at least twice through-out 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 guaranties the structural integrity of the welds holding the piece together.
