Yes you need MIL's.... there are a few different kinds out there now. I got mine a while back from dallas mustang, they were like 60 bucks for the set and are a no brainer to install. but since then I have seen some guy that has them for like 29 bucks a set. Not sure what the story is on them.. but they might be just as good. do a search on the corral, mustangworld and stangnet for info on those.
I got my H pipe from.

Turn around was a bit slow but it was right after the WTA events.
Below is GTR and my main guy I buy all my stuff from recommened them, but I had some paypal cash to burn up and they do not take pay pal, so I used mustangpartsonline.

but I usully get all my stuff from Ron Short. He is great for tech advise and great service. HE is well known on all the Boards. You can email him directly at
[email protected] He is great to deal with, but he can get buzy at times, but well worth the wait. (let him know I sent ya) HE actually told me to go through GTR becosue he could not beat the price. Everything else he can beat anyones price around.
Let me know when you get it ordered and I will give you a step buy step install on it. Basically the only PITA is removing the driver side header bolts, becouse MAC didnt make the sleave to fit great. But it is no biggy you just need some good visegrips and the back right out, then you replace them with bolts, I have the size in my data base for ya to get. THen you need to get 2 muffelr clams to clamp the H pipe part together. But I will give you a step by step install when you get it. shoot me an email when you get it.
