PROBLEM:
Most mufflers use some type of perforated pipe to allow air and
sound movement throughout the muffler. Louvered and Perforated tubing are the two types used.
Louvers with bent-in metal flaps create turbulence within the tubing, and turbulence slows air flow.
This slow flow adds backpressure which reduces your engines power output.
SOLUTION:
Perforated tubing
allows exhaust gasses to slide right through. No turbulence
and no added backpressure. MagnaFlow uses straight-through perforated
tubing with absolutely no restrictions.
