Power Flow Systems is now offering our Mooney "Quiet Pipe"" conversion for those Mooney's equipped with the 1st Generation Tailpipe. The 80640 Tailpipe is currently shipped with our PFS-16201GEN2 Mooney exhaust kits. Our Quiet Pipe design utilizes our most common PFS-8016 Muffler Insert for reduced noise. Some benefits of converting:

• Up to 13dB quieter on take off than your current PFS tailpipe for E & F Model Mooney's
• 3 - 5dB quieter for J models (the J model Mooney appears to be better insulated so the 1st Gen Tailpipe was not as loud as the E & F models).
• 1 - 3dB Quieter in cruise
• Smaller diameter where the pipe connects to the collector assembly.
• 1 - 2 Inches shorter in length
• No loss in cruise speed by changing from the 1st Gen to the Quiet Pipe.
• Installs in the same location as the original.
• Easier routing around the cowl flap actuator rod and out of the cowl.

Part # PFS-80640 for PFS-16201 Power Flow Systems Kits

Notice the arrow in the picture on the left. This is to point out that the new tailpipe can have two different end pieces to allow it to fit both a GEN-1 and a GEN-2 Power Flow System. The older style tailpipe was designed with a perforated stainless steel cone as its muffler, whereas the new Quiet Pipe has a complete basalt stainless steel packing inside(similar to glass pack).

The Quiet Pipe allows for a better fit and is as the name suggests, quieter!

This tailpipe is polished stainless steel. You have the option to upgrade to a ceramic coasted version, which keeps the pipe a nice silver color rather than turning brown over time. The ceramic coating is a $200 option.

Unless otherwise specified, Quiet Pipe will ship in four(4) weeks or less from time of order.

The photos in the listing feature both the Ceramic coated and Polished 80640 tailpipes.

*Note ALL PFS-16102GEN2 Power Flow Systems already have the quiet pipe installed.
