Exhaust System Overhaul and Repair:

Interior exhaust part surfaces deteriorate faster than outer surfaces. The Planexhaust overall process requires removal of end plates in order to inspect for hidden internal damage. Broken baffle segments can dislodge and block exhaust flow. Many exhaust components are manufactured from high-temperature material for longer service life. To ensure proper alignment, all parts are checked on precision jigs. Exhaust system failures can cause carbon monoxide poisoning, loss of engine power and even fire. This is why we subject all parts to rigid leak testing.


Our overhauled mufflers are all done to manufacturer specification.


These 321 stainless steel bends are mandrel bent to retain their original tube diameter throughout. They come in a variety of diameters and bend radii.


Made from 321 stainless steel sizes come in 2-hole, 4-holes Continental and Lycoming.

Slip Joints

These slip joints are expanded to a perfect slip fit and ready for welding. Made from 321 stainless steel.

Ball Joints

Made of 321 stainless steel, these Hydroformed ball joints work great for reducing cracking problems due to slight misalignments and vibrations.

Beaded Ends

Beaded ends work great for coupling tubes together such as tail pipes to mufflers. Clamps and beaded ends are both available.

Sheet Stock

Our 321 sheet stock comes in .025, .035 and .050 thicknesses. There is no minimum order.

Filler Rod

321 stainless steel should be welded with 347 filler rod. Often times not available through local welder's supply, we offer a variety of thicknesses.
