Buschur says one isn't required but I went to auto store with o2 housing and asked for a gasket for it.
I developed a leak over time anyway.

thats what i was thinking, overtime there might be a leak due to things getting hot and expanding. Is it a 3'' gasket or smaller??

Yeah it actually depends on the downpipe.
If the aftermarket pipe uses the stock donut you would need to modify it to fit.

Donut gasket?? or just a regular 2 bolt exhaust gasket...I guess it depends on which downpipe you have and what flange it had...

Stock is fine, just have to "clearance" it a bit to fit on the Megan flange.

are you talking about "clearancing" the height of the donut gasket or the inside diameter?
