x and h pipes

VOETOM,


There was a muffler company (Magnaflow I think) that did a exhaust on a car. They tried different ways of making the most HP/TQ just by changing the exhaust only. What they did was really wild. They had all different size pipes running along the exhaust that you wouldn't really thing would work but it did. I tried to find it the other night but I couldn't ... maybe you know what I'm talking about. It was a true "tuned exhaust" I guess you could say.
