Really soon I will be purchasing a MAC catted h pipe. Do I have to buy any other things like MIL or 02 extensions in order for the h pipe to work without acting up the computer, etc.? Also, should I get the prochamber or the orginal one (I want the louder one)? By the way, I have cat back 2 chamber 40 series. Thx for any input.

 

you dont need either of those things the mils are for catless H's are the 02 extenders are generally for cars with long tubes

 

I have the original Mac catted H-pipe and love the way it sounds.

Here is what mine sounds like with magnaflows: http://videos.streetfire.net/Player....1-460044BFE316

 

the only reason you'd need the 02 extension harness is if you have an 04.

 

just waht they said...^^^

mil's are only for cars without catalytic converters,

you should be good to go,
by the way, what did/ are you going to pay for the catted H?

 

where did you buy your mac catted h from..... im trying to look for them but cant find them

 

i got mine from mustangwarehoues.com but for some reason they do not have them on their website anymore.
