the hks is around $300 while the full cat back JIC is $580. that is hardly the same. maybe i missunderstood you. the $580 price is about normal for that system. rare trick has it for $585 and the axle back for $450. what is the point of having stainless under your car? if you show your car i see the point but otherwise i don't understand. if you got the cash go for it. other wise stick with the axle back. my two cents. by the way the semi Ti is $792. peace
