Gasket sizes?

[ersen.o]

Hey, i have a cobra un-res exhaust and berk decat pipes

 

i think my gaskets are blowing

 

what size would i need, pretty much for the 3 exits of the y pipe? so 2 that connect to the decats and 1 to exhaust

 

the ypipe is oem but i want the proper sizes for the aftermarket pipes

 

plz!

thanks

I'm sure all the y-pipes are 2.5" at the front flanges and either 2.5" or 3" at the rear.

We have them in stock, are looking for Nissan gaskets.... I can ship with the fenders

Just found a cheap hks y pipe local which I might get instead but what size do I need for that? lol it says 60mm and 65mm which seems smaller that most of the other y pipes? Will this matter? Surely hks know what they doing? Lol
