flowtech headers
 

Anyone running flowtech longtubes? P/N12104. I am wondering if I can get these to fit with a 351W and 5 speed. If anything, they probably won't be long enough to clear under the firewall. Anyone with a 351W and longtubes, please post what you are using. I know that kook's are really the way to go, but too expensive for me.

Is that part # you mentioned listed for a 302? If it is, then it won't work with a 351w. You will need long tubes for a 351w.
Personally, I don't like flowtech. I think they are cheaply made.
What about BBK or Mac They are good quality..........

To each their own. I'll never buy another MAC or BBK product ever. I've had two BBK H-pipes, both had fitment problems. Had problems with my MAC catback (chrome flaked off), but never had any troubles with my flowtech shortys or xpipe.
