Hello. I just joined the forum today. I have a 2015 ST, all stock. Just found out that the catalytic convertor needs replacing. Ford wants $2200 for a new one. Been doing some looking online and found a Mishimoto catted downpipe for $785. I'm wondering, did you have to do anything else to make yours work, or was it a direct fit replacement. Did you have an aftermarket cat back exhaust, or did you bolt it on to the stock exhaust.? I'm not concerned about power gains or the sound etc, I'm just looking to not spend $2200 for a new cat.
Thanks,
A
