I have MAC shorties w/ H-pipe and I love the sound. I'd do it again in a heartbeat.

Default RE: mac exhaust

i've had 2 stangs with mac exhaust and have been happy with both. beware though, the longtubes wont pass inspection, are a pain in the *** to install, have to be removed to replace the starter, and will hit on every speed bump.
but,you will get the best power out of them. i suggest getting the smallest collector size you can get as well as the smallest primaries, (1 5/8, i think) so you can to maximize your low-rpm torque

I have used MAC parts before,and will never again, the headers will bolt on right ONCE, Also MAC is known to rust, their "protective" coating can be scraped off with a fingernail

this is very true about their headers i would go with bbk or someone else as far as the pipes they are great they will rust a little but its only serface rust that can be taken off if you dont want them to rust put your own protective coating of them but they do sound amazing

Default RE: mac exhaust

If you get the Mac equal length headers, make sure you get some 90 degree angled short boots on the spark plug wires.
Anthing else tends to get too close and melts them... especially plug #3.
I think BBK ceramic may have been a better best choice because of the heat produced, at least in my car.
Next time around I will try those.
Here is a photo of the driver's side plug, which has plenty of space.

mac headers are known to be one of the least favorable header brands available.... most people will steer you towards BBK's or FRPP's

also on a car with minimal mods. i would recommend going with a 1 5/8 shortie over a 1 3/4 long tube... for low end power reasons

Default RE: mac exhaust

I installed my MAC unequal length headers and o/r h-pipe on my convertible, they fit great. I took that stuff off of the convertible and put it on the hatch and it still works and fits great. For an affordable, great sounding, and great performing exhaust I would go with mac. But why not save your 200 that's in the bank and do gears for 500, trust me, you'll enjoy the gears much more than exhaust.

#1 agreed
#2 agreed

you won't really bolt on any noticible power. (maybe , just maybe 20 hp tops) i have all MAC , long tube 1 5/8" , into mac prochamber, into mac catback.

it will sound great, ez install, not probs and i am on my second car w/ mac lt's. the mac cerama-coat is a much stronger coating than the standard one, yes the standard will rust.
1 3/4 is way to big, you'll lose power all over.

gears and tires will knock off minimum 1/2 second up to a full second. thats equivalent to 50-100 hp added.
