Frequently asked questions
How to bend your own exhaust pipe?
Using a torch and hydraulic jack: Heat the small section of tubing you want to bend. Once hot, place the pipe on a solid surface and use hydraulic power to apply pressure to the desired bend. This method requires care and precision to avoid overheating and damage to the pipe.
How do you bend an exhaust pipe without a machine?
Use a blow torch (for harder materials) or a hair dryer (for softer materials) and heat the area where you want to bend the pipe. Once the material gets extremely hot, put on heat-resistant gloves and bend the pipe by hand.
What are the benefits of a mandrel bent exhaust?
The benefits of mandrel bending stem from superior shape and structural integrity. Mandrel bent tubes are simply stronger at the points of bending than tubes that have undergone empty bends. They can handle more pressure, and they last longer.
Do exhaust bends change sound?
Although many people believe that exhaust tips are minor stylistic tweaks, they can significantly affect your car's sound and performance, especially if you had a particularly restrictive exhaust system beforehand.
