THINKING OF SIDEPIPES

Ben Drinkin said
But only 1 is functional.

I see. I got my reply from below;

"Exhaust, Lake Pipe 4, Steel, Chrome, Four 2 in. Diameter Inlets/One Functional, 3.5 in. Pipe, 73 in. Long, Kit"

Then read on to see;
"one functioning inlet tube and 3 dress-up tubes"

A little confusing!
