i m thinking off buying the warpspeed y pipe but i also was thinking of getting a new cat but then i saw a straight pipe for a maxima on ebay for $60 so it will replace the cat it says it will add atleast 15 horses. whats the total gain in hp for both of these together or should i got hi flow cat. thanks

 

the test pipe on ebay was dynoed proven when an intake, y-pipe, catback, and forced induction is added along the test pipe it'll provide 15 horses. if u only have the test pipe itself u probably will find 1-2 horses.

i suggest start with the y-pipe and an intake, tat's where u get most of ur HP and torque.
