I would recomend to not get the high Flow cat from justjap it is not as highflow as u may think as i found out and buy a catco cat or metal cat a little more expencive but well worth the money I got 3 quotes before I did the dump pipe back and they all told me to put the justjap cat in the bin they are more high flow than standard but not buy much and it holds the turbo back I got a catco now big difference
