does anyone know does this racing pipe work if you put it on your maxima? They say it gives you 9-16 hp

 

custommaxima dynoed it on a 95 max...heres the quote:

"We at CustomMaxima.com at first were skeptical at what kind of horsepower gain this pipe would produce, so we took a 1995 Maxima to a dyno shop and put it to put it to the test. An astounding 11.2 horsepower and 7.5 ft lbs of torque was gained when tested against the factory catalytic converter."
