An exhaust leak fix using a product that only takes minutes to apply. Permatex Ultra Copper Maximum Temperature RTV Silicone Gasket Maker Review.
Reviewed by Mark DT
This is a short and sweet review for Farkle My Ride on a cheap and brilliant product for those that like to work on their own bikes. I discovered this exhaust leak fix this past winter when installing a Danmoto slip-on exhaust (eBay link) onto my wife’s Kawasaki Ninja 250.
The motorcycle exhaust leaked where the slip-on met the pipe into the header. First thing tried was a factory Kawasaki exhaust gasket to see if it would work with the new slip on. The clearance, however, was way too tight. Time to look for an aftermarket solution as the exhaust leaked in two joining areas and I was keen to get it working properly.
Permatex Ultra Copper Silicone is a sealant that withstands high temperatures and is ideal for sealing exhausts or any other high heat, high pressure applications. It comes in a three ounce tube, and is as easy to apply as squeezing toothpaste onto your toothbrush.
The manufacturer states “The most advanced, high temp RTV silicone gasket available. Sensor-safe, low odor, noncorrosive. Superior adhesion. Three times more oil resistant than conventional silicones; eight times more flexible than cut gaskets. Temperature range -75°F to 700°F (-59°C to 371°C) intermittent; resists auto and shop fluids and vibration.”
All I can say is it worked exactly as claimed and was dead simple to work with. If you are buying an aftermarket exhaust for your motorcycle I wouldn’t hesitate to order a tube of this stuff at the same time to ensure everything is sealed air tight and your motorcycle exhaust is leak free. This is an easy and inexpensive exhaust leak fix for leaks in the joining areas when installing an aftermarket exhaust. Highly recommended!
