Well i picked up a apexi ws for free today but ididnt come with any gaskets or bolts. So i just want to know where to get some gaskets. Will auto parts store have the size i need

 

i have the same exhaust and got a replacement gasket at the "zone", was a while back so i dont remember anything except it was a mr gasket part. i would take some cardboard trace the flange and take it with for comparison
