Do you gain like 14 horse power with Random Tech Hi-Flow Catalytic Convertor. Is this true or just a statement. Any one who has it or know about, I wana make sure before I buy it, any response be really appreciated.

 

a y-pipe barely gives you 14hp expect like 1-5.

 

if you are reffering to the one on CustomMaxima.com, if you look closely at the dyno results, it says RT CAT WITH CATBACK SYSTEM. Expect minumal gains by itslef.

 

In most cases no more than .5hp - 1hp.
