Feature 1Allows short time 400 high temperature continuous work, 360 high temperature without deformation. 2Prevent voltage and current instability from causing damage to the motor. 3Low power consumption, long service life, depndable to use. 4304 stainless steel material, more corrosion resistant, more convenient for welding. 5Fire and heat resistant, flame retardant material, not afraid of open fire.Condition: 100% Brand NewItem Type: Exhaust ValveMaterial: 304 Stainless SteelColor: As picture shownApplication: Universal for most carCaliber: Approx. 50mm/2inInstallation:1. Determine the installation position before or after the drum according to the displacement of the vehicle2. Draw the position and cut (straight and curve pipe both can be cut)3. Determine the position of spot welding, straight and curve pipe can be directly welded on the exhaust pipe4. Shine a torch on whether there is any light leakage, then clean it and welding to seal5. Then connect the pipe and finish the welding of the drum (the elbow can be rotated) .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Fuze1 x Remote Control Key(Shipped Without Battery)1 x Car Charger Controller1 x Exhaust ValveNoteNew and old models of this protect will be shipped randomly.
