DP w stock cat

[ANDYS87]

Who sells a 3 inch stainless down pipe that will fit with the stock catalytic converter? I need to have a cat present for inspection. They don't need to know its gutted. It's just a visual check.

I like the RJC 3 inch dp. I think my cat is one from kirbans- not stock.

No one sells a reduced neck downpipe. How big is the inlet on your cat? You could take it to a muffler shop and have it expanded to fit the downpipe or have a larger neck welded on. Better yet, buy a proper highflow cat that fits and be done with it. Random Technologies cats barely hurt performance, almost imperceptibly.

Stock cats in good condition are not easy to find. Take your DP and converter off and keep them for another day. Buy a 3 inch cat and be done with it.
