y-pipe fitment

[egod]

If i get some headers with a 3" collector and a catback with a 3" catback will i need a slipfit y with 3" inlet and outlet diameters? will they all be catless unless otherwise noted? I am going to go catless so this really doesn't matter, I already have a hooker catback and I wanted to get the ebay headers and I need to figure out what size y-pipe I need. Thanks

i've been looking but i can't tell if all you need is a y-pipe with matching inlets and outlets or if you have to find a matching one. anybody got any input

By a Y made for that car and it will fit. The back of the Y shoud be tapered down to like 2 and 7/8ths or so. this way it can slip fit to the cat back. ask the seller if it will fit.
