ok so I got a 78mm bbk throttle body and a set of longtubes for my car in a trade. the throttle body was uses but in good condition I already installed it the other night. the headers are brand new never been on a car before the only issue is they don't have a brand on them and may be ebay's. there really nice looking actually and there stainless steal all the welds look decent but idk if I should buy a new x pipe and do it or not. I'm having a guy put a new trans in my car within the month and debating on having him do it when the trans is out or not. what do you guys think?
