Hey guys, just wondering about my order of O2 extensions #17781. I got an email saying they were out of stock and would be in stock in about a week. After 2 I figured I'd throw up a thread to see whats up. Gonne be getting my H pipe friday so I wanna install the headers this weekend and need those extensions. BTW, do I only need 2 extensions for longtubes and a catted H? Thanks.
