MagnaFlow Mufflers

[mike kojima]

Louvered is bad!  When doing backpressure checks, I
found that louvered cores are as bad as stock
mufflers, sometimes even worse.

The louvers create turbulance which increses the
boundery layer in the pipe, effectivly shrinking it's
diameter by up to half it's size.

Stay away from louvered cores and those universal
exhaust flex pipes.
