the Mac LT is also one of the few that will fit onto a GT40P head also.

That's what i am getting for my GT40P's when i put them on a fresh block in a few months

 

[CrystalWhiteChristine]

[Javi]

no complaints here after a year..
Also id recommend you to get the Ceramic coated

 

[OnyxCobra]

I wouldn't know if I have complaints yet cause my car has been on jack stands since July lol. I wanted the ceramic coated but i got what I feel was a screamin' deal on some silver ones.

Sweet any one wana upgrade there headers and sell me the mac LT?

 

[two95s]

I used the same set on two different cars over a six year period. I'd say five out of the six yrs I had them out twice a year.
I don't have lift, so installing them with the engine and trans still in the car was a pita.
It would take forever to get the flanges lined up with the bolt holes in the heads.
Burned up my o2 sensor extension once. (My fault of course) Not cheap.
Since the car was lowered they scraped on speed bumps, ect.
Because of the camshaft, the engine shook, which caused them to bang on the floorpan.
Any time I needed to remove the trans, they had to be removed as well.

All I can think of now. Brings back bad memories. lol.

 

[OnyxCobra]

hmmm, well normal people don't have to remove headers nearly that much lol. I hope I have better luck with mine :thumbsup:

 

[CrystalWhiteChristine]

Ight so im picking up the Mac long Tubes tomarrow, Question should I block my EGR or will that cause issues?

 

[OnyxCobra]

If they are for your year they have a bung for the EGR, not sure how you connect it though cause it's in a weird spot on the mac headers.

 

[CrystalWhiteChristine]

Yea they are 94/95 specific headers,I took off the egr and plug the vacuum line, now i gotta put a plate over the egr port, I guess ill connect that electrical connector to wat it was originally connected to, Onyx wat did u do with ur egr?

 

[OnyxCobra]

Mine is deleted. I have a cap for my header and i bought a delete plate for the intake manifold. It's the same block off plate used to block the fuel pump on Ford 351C & 400 engines. I bought one and it looks exactly like what others advertise for much more money, i got Mr Gasket #1517. $7 on summit.
