17 May 2026 1 min read

What Is a Straight Pipe?

A straight pipe is a free-flowing section of exhaust tubing designed to maximise airflow and simplify exhaust routing.

It’s commonly used for:

  • Custom exhaust fabrication
  • Performance-oriented setups
  • Replacing restrictive sections
  • General workshop and fabrication use

With fewer restrictions, straight pipes support smoother exhaust flow and a more direct, responsive system.
