no problem man like i said i have enough room, but if for some reason it does rub the lip a little bit just trim a tiny bit off the lip right above the exhaust tip no one will notice the little bit gone from the lip. If your exhaust fits like mine however you will not need to do it.
Im not sure what page they are on, but i believe there are at the begning of my build thread i have pics of my exhaust installed the cars came a long way since i put the exhaust on, but the same exhaust is still there. There is a link to my build thread in my signature if you want to check it out and see how it looks on my car.
