High Quality Truck Parts, and Flexatube; A legacy in Producing Exhaust Flex Pipe and Flexible Metal Tubing.

We have been manufacturing quality exhaust flex pipe since 1956. In fact, we patented our unique tooling that we use today. This patent strengthens the tightness of the wrap. This patented roller method allows us to guarantee the pipe you buy from us does not unravel. Without our patented tooling, it would be difficult to make the claim that flex pipe would not unravel. For more than 40 years, we have led the industry in flex pipe, because customers have always said;

“your HQ Flexatube brand exhaust flex pipe does not unravel!”

Manufactured in Troy Michigan, the heartland of America. Visit our Factory in this short video: Manufacturing Equipment Video
