actually all the Y pipes that have 2.5" and 3" merge will have high gains from mid to top but drop in low end...
here some examples..
Tanabe Y pipe VS MotorDyne Y pipe
Tanabe has 60MM dual to 70MM merge.
Stock Y pipe Vs Motordyne Y pipe (stock car)

so wow.. gratz on ur 40$ Y pipes.. cheap Y pipe ftw
