rather then going to nissan and get them at a higher price VS any parts store, i'm going to pick up the gaskets at a local store, anyone have the sizes tho? I've heard nissan prices are about $5 per gasket so all together $20... i know other gaskets are normally going for like $2.

i would assume the whole HR y pipe is 2.5 so i need that x3 and then i need a crush ring for my coupe midpipe going to muffler. i've seem 72mm but not 100%



OR do you guys just reuse the OLD ones? and only replace the crush ring at the end.
