Exhaust leak (o2 housing and downpipe)

so i was wondering how much it would effect my car if i had a small leak between my streetactionmotorsports o2 houseing, and my buschur downpipe.

im missing the rubber donut gasket, hopefully i can find one somewhere and not get ripped off at mitsu... so do you guys know if with that gasket, it will stop the leak?

also i was just wondering how much it would retard performance.

thanks in advance

i dont think its a rubber gasket, but having a leak on a turbo car isnt that bad... i mean it just means the gases have a faster way to escape rather than going all the way thru the exhaust...

it might make an ugly sounding rattle

some gasket will fix the leak

and if it does retard performance it wont be much or even noticeable

exhaust leaks will spike AFR readings if you have a wideband.. that might be what someone told you.. I havent heard about actually running leaner cause of an exhaust leak. Not sure though.
