so, u mean i keep the stock catback? does the catback increase power?
i have the same idea as well. cuz catback cost me too much to spend.
i just decide get injen intake and header.
but the "hissing" looks so strange. i think i need time to used to it.
should i change to other header if i have chance?
Just change the flex pipe.i think you can get a double layer one.
