My apologies, I bought the Borla S-Type cat-back and added the quad black tips to the system. When I received them from Summit, they were already welded on. Had some birthday money to blow, so I went all in. Summit sells just the tips, noticed the Borla ones say “will not fit OEM”.. I see other quad tip brands on their site, perhaps give them a call and see if they’d fit. Sent from my iPhone using Tapatalk
