Why buy mandrel bends?

Mandrel bends maintain the same internal diameter all the way through the bend.

Crush bends are just like they sound; the piping is crushed slightly while bending, decreasing the ID of the pipe.

Mandrel bent is the preferred method, but requires special equipment. Virtually all of your local exhaust shops can only crush bend.

A truly excellent exhaust can make a big difference to performance. You want to maintain velocity of the exhaust gases with as little restriction as possible. The reason is the scavenging effect on your engine. What this means is that with an excellent system, each exhaust pulse, as it races through the piping, leaves a slight vacuum behind it to help suck the exhaust out of the next cylinder when the exhaust valve opens. This helps make your engine more efficient. You want to pull in all of the air possible, and pump all of the exhaust fumes out.

As you introduce restrictions to the exhaust, you begin to reduce the scavenging effect because you don’t maintain the same velocity through the system.
