I have MAC ceramic l/t's and I love them. I used Stage 8 bolts from summit and went to Ford and bought new gaskets. The headers lined right up and there are no clearance issues whatsoever. And if your wondering on installation procedures, drop the k member, its the only way to go. You can get a write up on fnsweet.com Hope this helps...

 

Thanks a lot everybody that helps out a lot

 

One more questions...is there any problems if I go with an h-pipe not made by Mac? Will it fit up alright with a different brand cause I know on the websites it says you must use a Mac mid if you have Mac LTs but is that really true?

 

Just got mine installed. They are open headers for right now. They sound great... well any open header would lol. The shop that put them on didn't use the bolts the kit came with but instead used different studs which they said would keep them in better. Also they could only get 2 of the 3 bolts back in the starter motor because the pipe was in the way. Besides that I don't have a problem with them.

 

Yeah I heard that is true. I am getting a new Mac o/r H for the LTs maybe tomorrow. It's like 169.00 from AmericanMuscle.com

I have a BBK midpipe and it fits fine. MAC just says that so youll buy their product. Its not necessary tho...

 

Are lts worth getting? cause i was looking at the mac lts also

 

I have the LT's from MAC. GO w/ the prochamber. Bad *** sound and lots of tourqe. The only thing I didn't like about MAC LT, whenI pull the car out from storage, there is surface rust ??? CCAn't get rid of it all ???There ceramic, thought they did't rust. Called MAC and they said that was normal. Other than that, the LT where worth it(8 hour install worth it).

 

thanx

 

does the prochamber eliminate the cats cause i dont wanna have to swap out for emissions?
