Am I gonna need a double hump crossmember to run tru duels headers..?

Yep...Jegs has some fair priced. But if yours is a Supreme they might not fit, even after tweaking. Summit has the only bolt in double hump crossmembers I've found for a Supreme, but they're just shy of $300. I went to a local exhaust shop with a good reputation and they fabricated a second hump on my original for $88 after tax. If you go the shop route, ask questions and make sure they do it right...notch it out and weld in a solid steel half circle of pipe. The shop I went to uses 6" diameter 1/2" thick. Either mark the crossmember where the notch needs to be, remove it, and take it to the shop or you can just drive over with open headers and pray that you don't get pulled over (I did the latter). Unless you or a buddy is decent welder, then you can just do it yourself.

You COULD have a y-pipe fabricated to use the single hump, but I found this to be more expensive than getting the second notch.

Very nice product, fits all g bodies. Not sure on price, or you could just make your own.

I have a Supreme and the JEGS crossmember bolted in just fine. The frames on the Supreme aren't any different than the frames on the rest of the G bodies, except the wagons and ElCaminos.

Go for the iceman crossmember. He has a link on Maliburacing.com. That's what I have in my monte and I must say that the welds, bends, etc are top notch. Plus cheaper than a Jegs crossmember..

Is the iceman crosemember legit? Doesn't look that good.. looks to thin and how much is it? Doesn't show prices..

if your gonna race it, you need a good solid crossmember. http://www.transmissioncenter.net/gforc ... NAod5V3J2A
Im not planning to race my car, but I put this one in anyway, mainly because its strong and stiffens the frame. looks good too!

I know the frames aren't any different. It says right on their website, "Does not fit ANY Cutlass Supreme models or El Camino." So I called for more info and was told by a Jeg's tech rep that the bolt holes on SOME Supremes are located slightly different than a non-Supreme, and they say it won't fit ANY on the site to cover their *ss. The rep claimed to know someone who wasn't able to use a Jegster on his Supreme. I don't personally know anyone with a non-Supreme to let me compare crossmembers so I just took my car to a shop. Also, for some reason I recall the Summit brand being more expensive when I was looking for a crossmember, which is why I didn't get it...oh well
