headers and their exit/Highboys
This is a follow up on Elks situation and Im sure countless others,Im waiting for my motor from my engine builder (460) swap,considering L&L,Maddog.My question is what are the positives in running them inside the frame area and the negatives,,,,vs versa with running them outside the frame area.And if you can remember the hurdles that you ran into,again Im doing the 460 swap ,360/390 diffrent issues as well,,,and maybe what mufflers you followed up with Thanks

L&L'S 460 conversion 3/4 block huggers with stage 8 locking fasteners. In my 74 Highboy.
If you have a bed mounted toolbox this is the way to go. I wanted fender well exits, but I wanted the toolbox more.
No fitiment issues. Went in without lifting the motor or anything. No leaks no B.S.

I am running the same L&L chassis exit headers and there was no fitment issues as already mentioned. I've even taken them off a couple times and put them back on with any trouble. I just wish that the guy who did my exhaust looked as good as the headers.

I haven't any experience with the fender well exits. I know there are a couple of guys on here that have them though. If there isn't any steering issues I would run them for sure. Way easier to run exhaust that way.

Mine's not a Highboy but I did just buy the Mad Dog fender exits...
There was some fitment issues but nothing I would call bad.
My feedback is in Post #5 here:

There's also a link to my Flickr account with a bunch of photos of the headers.

L&L require their perches as well. At least that's what they said. That was one of my (oh, I really need those?) moments. Tool box existance is dependant on your choice of exit I suppose.

How do those flotech's fit for the FE highboy's? I'm assuming they are pretty thin tubes for the price they list for? And has anyone tried the Hedman's for an FE with good results? Looking for the best economical header right now since mine are a mess.

L&L
I called L&L today,and it is official they no longer carry nickle plated headers.The quality of the header hasnt changed,just the coating.Their reason was their vendor for coatings has gone out of business.So they will be adjusting cost on their web site soon.So ceramic coatings are now in order.Business wise "they arnt going anywhere" just passing it along.
