mac long tubes

Well the old ones without the coating would rust after a couple years, but mine havent. The new ones with the coating look great, my friend is selling his along with a prochamber. Go to my site for some sound clips.

if your that worried about the macs just delete the egr as thats where most were saying the probelm was comming from. or just run a wire brush threw them to get any gunk out.
But i have yet to see any probelms (in person).

I wouldn't put a MAC product on my lawnmower.
Don't get the MAC longtubes for your 4V or you'll be sorry. Hooker's, Kooks, SHM, BBK would be the only L/T's I'd consider. There are many things you need to look at like Ground clearance, tranny removal (with or without removing header), power etc.
With header's it's just like everything else you get what you pay for.

But don't believe everything you see on the internet...even from me. I don't like to give out misinformation but state things based on whatever research I myself have done.
I am running Kuhmo Ecsta Supra 712 255/40Zr17's on stock rims right now. When I go to the track I ease out the clutch from about ~2500 rpms. My best 60ft. ever is 2.05ish. The car without nitrous, tune, and Driveshaft,clutch,flywheel ran 8.92 @ 82.1mph. That was with Dirty IMRC's as well.
To really track well in any of these modular V8's (esp. the Cobra) you have to launch at 6500rpm. But that of course will snap rear ends or input shafts, neither of which I have the money to replace. So until I get to beef up the rearend and get slicks/wheels She'll be very limited at the track. I'm shooting for mid-low 7's @low 90's with traction after the nitrous and fuel gets sorted out. (Which my Customized Nitrous Module and Jets just returned from Venom :evil6: )
On to the Headers I will just tell you that I personally would not get MAC headers. At the very least if your looking for a cheaper set of headers get FLOWTECH. Made by Hooker, virtually the same header as the HKR-6229. If you go to Oreilly's I believe they are fairly inexpensive.
Other than that here Are the Breakdowns.
MAC L/T Headers - 1-5/8" Primaries. Least Expensive. Suspected poor workmanship and quality control issues with this product. Has been found as the source of several instances of catastrophic engine failure. Cheapest of all headers, fit is fairly good, ground clearance is average. Must remove Passenger side header for Tranny removal. You could get away with running these if you thoroughly inspected each mating surface and inside the flanges of the Header for slag or Flaking coating and remove if possible. This will reduce chances of foreign debris entering the cylinders through reversion/scavenging.
FLOWTECH L/T - 1-5/8" Primaries. Inexpensive. Made by Holley (Hooker) and virtually 95% the same as the HKR-6229 Header made by hooker. Available with different finishes, probably could have them jet hot coated. Fit is decent, ground clearance average. Not sure if tranny can be removed without removing header.
BBK L/T Headers - 1-5/8" Primaries. Fairly inexpensive. Great quality, good power/sound. Fit is very well. Only problems with the BBK's tend to be the Ground clearance is sub-par...and you must remove the passenger side header for Tranny removal. Usually comes with 02 sensor extensions. Customer Service is great as well. (if ever there is an issue)
HOOKER L/T Headers - 1-5/8" Primaries. Moderately expensive. Great quality. Great fitment. Best Ground clearance of all brand L/T Headers. Tranny can be removed without removing header. Only known issues is occasional problems/leaks with the passenger (I think it's the passenger side) slip-fit collector. Thorough installation may prevent this.
KOOKS/CUSTOM L/T Headers - 1-5/8" to 2-1/2+" Primaries. Very Expensive (well over $1,000). Headers to be made to fit any application from any number of materials. Mostly Stainless. Can be tuned, and stepped. Step headers with 1-3/4 to 1-7/8 sectioned primaries work well in most applications.
With any L/T Header you can get a custom Made shorty H-Pipe (would sound best IMHO), or a Catted/OR X-Pipe.
Get Stage8 Locking header bolts no matter what.
Only use Factory Ford Exhaust Manifold Gaskets Best quality of any period.
That's about all the info I have...know understand I have factory headers still. This is just based on research I have done, and things ive seen through my years on the forums.

i was running 245 45 17 visa on stock rims with no hook-up, stock everything except the things listed in my sig (bbk cai) and ran a 9.39-10.19 2.3-2.6 60ft times (9.39 was a 2.32 60ft). think the eleavation is around 600 ft. speed was 73-78. i want 7.7 and i'm on to the body paint etc.
okay the flow tech's are very good on cost. think i'll start looking into a custom x (more power) but i think i'm gonna have to get cats. (rumor is they're bringing back vehical emissions testing here) so now it's on to a cat back also. was thinking magna flow? borla sounds the best that i've heard but i like the magna sound to and the extra 300 bucks(maybe i'll get gears with that?)
