double hump x-member. Which way is correct

[ciara]

I have an 84 stang with a 351w. I put on a double hump crossmember, but not sure which way it goes on. There is a big hump and a little one. I have the big side on the passenger side, but with my long tubes headers and wanting to put collector extensions on it. The extensions will hit the crossmember. Do I just need to get the pipes bent or is there something else to do to make more clearence? How do you guys have you exhaust ran. I want to have the extensions with Dynomax bullet mufflers. Or will another set up be better. The car is drag only , but I don't want to run open headers all the time.
