THE BENEFITS OF MANDREL BENT EXHAUST SYSTEMS
The table below shows the cross-sectional area for press-bent compared with mandrel-bent pipes.
In the Press Bent column, two numbers are shown. These correspond to a 20% reduction on a shallow bend, and a 30% reduction on a tighter bend.
As can be seen from the table, a 2 1/2 inch press bent pipe is actually smaller in cross-sectional area at the bend than a 21/4 inch mandrel bent pipe!
|Press Bent Area
|Mandrel Bent Area
|2 1/4 ″||3.13 / 2.74||3.92|
|2 1/2″||3.92 / 3.43||4.90|
|3″||5.65 / 4.94||7.06|
Any exhaust system is only as good as its weakest link, so why settle for restrictive ‘press’ bending on a system that is probably sold as giving better performance and economy?
There are just a few companies in the UK who offer mandrel bending, and fewer still who offer this service on custom build exhausts.
Cybox exhausts give you the assurance of Mandrel Bending with the guarantee of optimum performance and a lifetime warranty.
