I went looking for some headers online I've found:

Dynatech coated and stainless steel

and

Pacesetter coated, steel
http://store.summitracing.com/partdetail.asp?autofilter=1&part=PSM%2D72C2237&N=700+4294908153+4294924744+4294907958+4294923429+ 115&autoview=sku


and

Pacesetter uncoated, steel
http://store.summitracing.com/partdetail.asp?autofilter=1&part=PSM%2D70%2D2237&N=700+4294908153+4294924744+4294907958+4294923429+ 115&autoview=sku


are the dynatech ones a good deal? or am I just looking in the wrong place? Also I'm trying to stay emissions legal.

haha, nah, super comps bring back memories of almost constant rattles, reduced turning radius, and daily retightening. it wasn't on an f-body, but just out of spite I'm never buying another super comp, EVER. :bang:

cheapest price and free shipping, coat them and wrap them yourself :)

I went with Jet-Hots (essentially Super Comp's but with thicker flanges and a little better welds).

I dont think there is much difference between Pacesetters/Hooker Super Comps/and Jet Hots. I'd go with whatever is cheaper. At the time, I got in on a group buy on Jet Hots ($450, i think?). They all make emissions compatible headers, but they are going to relocate your cat pretty far back, which might fail a visual inspection.

Do not wrap a header on the street!! They collect mostiure and will rust them in short order. even if they are coated, the constant water on them will eat it in no time!!

coating them yourself can be a very effective option. so long as you prep it right, and get an even coat, in multi layers.

i dont know how to coat it though, so that might be a problem. how hard are they to put in? and do I HAVE to use poly engine mounts to prevent the Y-pipe from slapping the floorboard of the car?

coating a set of headers yourself will never compare to a professional shop who has the proper equipment to do it.

As for the header wrap, the shit is garbage. Even a lot of circle guys have gone to ceramic coating cause they're tired of replacing their headers ever year

can you be emissions legal with LT headers? or does it vary state to state?What else do you need when installing the headers other than the headers themselves, the time required to install them? I read something about poly motor mounts and a tune so the rear o2 wouldn't bring up the SES light. Do you need to buy a Y-pipe?

MrCadillac

the rear O2 deal is only if you delete the cats. I don't think NJ will allow the use of LT's, since you move the cats. I'd look into your emissions laws. you can alwasy keep the stock manifolds and pipes, and swap them on for the emissions part. Some may say that is shady, but what is shady is not letting us run long tube headers on a street car!! I'm glad I don't have emissions testing!

Buffman is right, it won't be the same as getting them coated by a pro, but if money is really that tight, and you don't mind redoing it every year or so, go for it. me, I have mine procoated... now I just need a car to put them on!

Pace Setter Coated LT's, and no major problems with them. I am lowered, and they are decent in the ground clearance, a couple of scrapes every now and then.

Yea, you will need a new Y-pipe. Most Collectors are 3", so there are alot of Y-pipes out there. I have the Pace Setter Y on mine as well.

Yep you do

are you puting cats on the y pipe? or gonna put them on when the emissions pricks come to town? Othwise, good luck passing(it can be done tho). But not if they inspect hardcore, and expect cats to be there. also, don't most emissions places fail you for moved cats? Just making sure ya don't end up screwing yer self. :)
