The improved
flow that comes from a mandrel bent pipe makes RJ Custom pipes, and systems
superior. The mandrel bending process maintains a constant inside diameter,
even through pipe bends. Flow area remains consistent, increasing flow
more than 35% compared to stock, serrated bent pipes. |
| As you can see in figure A, the
3" inch pipe that is mandrel bent measures 3" inches at the center
of the bend. True 3 inches throughout the pipe will give you 35% less backpressure.
Less backpressure equals increased horsepower, torque, and better gas mileage.

As
you can see in figure B, the 3" inch pipe that is stock bent measures
21/2 inches at the center of the bend. You don't benefit much by having
a 3" inch pipe with 21/2 inch restriction in each bend. Your exhaust
system is only as good as its weakest link. Why settle for restrictive
sub par bending. |
