Hi All

I was just looking at random ISF stuff on the net and came across a HKS Cat. Part number is 33005-AT004. I have done abit of research but cant seem to find out if it is just 2 cats or a whole midpipe for the ISF. If it is a whole midpipe, its looks like they have revised their previous midpipe which is discontinued. The price of this part is around $1300-$1400 so I would hope its a whole midpipe.

Can anyone who can read jap look into this as it is mainly listed on Jap sites and the translation is confusing.....

If it is a midpipe, it seems to have x2 150 cel cats and a muffler instead of a resonator.

I'm thinking its just the cat that mounts to the stock midpipe. I emailed two places - they said the part number is not in the system yet.

Keep me posted if you hear different. I'd be interested too - i've been looking for the midpipe for a while.
