Does anyone know the size of the nuts and bolts I need for my Y pipe for my 03 maxima. I want to pick-up the hardware at Home Depot. I know there is a set of 3 nuts, a set of 3 nuts and bolts, then a pair of studs with nuts at the cat. Any info is appreciated. Thanks.

 

Is this an aftermarket performance ypipe or factory? I usually get all my hardware (stainless steel) from Ace hardware, they have lots of metric and SAE, I used 3/8-24 bolt and nuts most of the time along with some lock washers. I switched all my Cattman Header hardware with longer SS bolts and nuts along w/lock washers....
