Mandrel
bent exhaust pipe is the most critical part of exhaust system because it is
more prone to jerks and mechanical impacts. Weather impacts also test its
quality especially in cold weather. If the vehicle is used on rough and muddy roads,
the chances of getting rust are pretty high. And, if you are using old vehicle,
you may need to replace the mandrel bent. When should you change the mandrel
bend pipe? If you feel loud noise, drop in mileage, drop in acceleration and
smell of burning gases, it is time to drive your car into the garage for
mandrel bent replacement. I wouldn’t suggest repairing because complete
replacement is not a costly affair besides being more reliable solution.

Always
prefer direct fit mandrel bent whether it is made of stainless steel or
Aluminum. 90 2PC Aluminized, 45 2PC Aluminized and 180 U Aluminized mandrel
bends fit to numbers of old variants designed with the provision of connecting
two inch wide Mandrel pipe. Aluminized Mandrel pipes are available in 2.25, 2.5
and 3.0 inch sizes also. The stainless steel exhaust pipes are also available
in similar sizes. Here, the shape
becomes the priority because customization of bend at garage is not a practical
solution. Some universal mandrel bent kits are also available. For example, 2.25
inch Honda Civic Catback Stainless Steel Mandrel Bends kit sets fit to all DX/LX/EX/Si 1.7L sedan and coupe variants
of 2001 - 2005.
