Exhaust/Downpipe install...how many gaskets needed?
I know my way around my subie but have never installed an Evo exhaust and downpipe. I will be installing a HKS 2.75''downpipe and a Magnaflow 3'' Cat Back exhaust. Im just wondering as to how many gaskets I need. Heres how I see it....
o2 housing - d gasket -downpipe - gasket - catalitic converter - gasket - exhaust...
I know I need the donut gasket but do I need the other two between the cat and the exhaust. I know I will need around a 70mm gasket so just gotta make sure I need them before I buy them. The downpipe is used so it has no gasket... Thanks for any info guys

donut gasket can be reused if it's in good shape and is the right size
1 for downpipe -> test pipe
1 for test pipe -> catback
exhaust depends how many pieces it is, total number of pieces - 1 is how many you need. if exhaust is 3 pieces, you need 2 gaskets. mine was 2 pieces so i only needed 1 gasket
anyways, why a 2.75" downpipe when the rest is 3"?
