The unique flared-end construction of the Precision Port™ system enables it to outperform any standard port tube on the market. Conventional tubes suffer from nasty turbulence at the entrance and exit of the port, producing unwanted noise and poor sound quality. The Precision Port™ system overcomes these problems and as a result can actually produce a gain of up to 3 dB in output! Now you can experience good looks, low distortion, and superior overall sound quality thanks to the Precision Port™ system.

The 2" model now comes with starter holes on the rear of the mounting flange, allowing the user to decide whether to use 3 mounting holes, 4 mounting holes, or none at all! All you need is a standard twist-drill to make your custom mounting decision. The central tube can be cut to any desired length, with a maximum overall port length of 279mm. Once the pieces are cut, the system can be permanently bonded with ABS pipe cement. Dimensions: • 133mm outside flare outer diameter • 108mm cutout • 106mm inside flare outer diameter. Also available in 3", 4", and 6" diameters. Proudly made in the USA!
