(*) A Quiet Tuned Pipe or a Single (Q)uiet Tuned Pipe is a chamber with baffles that tune the system and quiet the exhaust. A Quiet Tuned Pipe is quieter then a Muffled Tuned Pipe. A Double (Q)uiet Tuned Pipe, as seen at the bottom of the Marine Tuned Pipe page, is even quieter and can be used on airplanes. Most of the Single (Q)uiet Tuned Pipes, shown on this page, can be made in a Double (Q)uiet version. Contact us for more information. |
Please see our NEW Double (Q)uiet pipe at the bottom of the Marine Tuned Pipe Page. They have more possibilities than just marine and helicopter applications |
