IM AN IDIOT... I tossed the flange on the passenger side cat pipe that helps bolt the muffler to the cat
(see numbers 12 & 13) and I need this part!!!
Unless you have installed Corsa or a full exhaust, your catback (ARH, Kooks, Magnaflow, GTHaus) reused this piece. Please also consult Fig 1 seen here in Corsa's install instructions:
Obviously, will pay you for this part if you have it available, this will easily fit into a medium USPS Priority Flat rate box
