thats quite a deal.. But you should really be considering if it's too good to be true... I personally have mac LT on my car and I am personally extreamly happy with them.

You must remember that putting headders on DOHC cobra's isn't fun by any means.. Meaning you only want to do it once. I'd be concerned with bad welds and possible flange failure with those pace setter's. I really haven't seen anything from them that looked good in quality.

+1 you only wanna do it once. I did mine when I did a tubular k member so it was a breeze.

I went with mac long tubes cuz that's what came highly reccomended and love them. If you're not planning pushing 21+ psi don't bother with headers! Not worth it.

i picked up 10hp with the addition to the LT's over stock mani's.... you have to ask yourself it the price of headders and the p.i.t.a to install is worth the added 10hp...

I did it for the sound and the slight performance gain. FYI.. get stage 8 locking headder bolts for sure if you do change out the stock mani's. Also get some decent exhaust mani gaskets as well.

Im so glad I have Longtubes on the way...WIN!

i wanna get a pair of long tubes while im gonna be changing my k-member and thought that the cheaper ones might do well but im reading that pacesetters have a tendency to rust out really quick, so maybe they will be good with a little blast sanding and ceramic coating?

Its a complete joke.
You put Longtubes on a Marauder you gain about 20rwhp NA and about 35 SC.

There have been guys who bolted them on with No tuning and saw a .3 second reduction on ET's. Supercharged guys, after tuning knock .5 seconds off like nothin!

With 21+ psi it'll be more like 40 hp gain trust me.

Stock gaskets from a ford dealer are just fine $40 or so I know alot of people that use them and they have no issues what's so ever. And stick with the stock header nuts too you dont need locking ones. Just buy brand new ones.

2 years with mine and no issues. Do it right make sure you clean off the exhaust runners before you slap on your gaskets and bolt up the headers. You will be amazed how many crap jobs there are and people end up w leaks.

Take a drill with the wire brush attachment and get off all the old grime and build up make sure it's smooth and then put everything on.

Granted I have a xxxxxx, with stock manifolds and made plenty of power. To me they are not worth the $ or the hassel. And if you are going to do it:

Do it once do it right and put some quality headers on there. I don't thinks of those when I think quality

Even if you coat them they will still rust. Buy some Kooks take the hit.

Do it once do it right
