Mac H Pipe Installation Tips?

Finally bought the mac h pipe after much contemplation (man I am such a cheap *** lol) and wanting to know maybe some tips that will make it a little easier. I have jack stands but am going to look at renting a lift at a little DIY place. Just wondering if I need to pick up any special tools or anything. I watch a video and it looked fairly easy, but they had tools that turned a 15 minute bolt into a 30 second bolt

How much louder do you think it will be also with my flow 40's

Thanks for the help

Here the link to it. http://www.ebay.com/itm/MAC-Ford-Mus...e5f4c6&vxp=mtr

Lift or no lift you will need various extensions and at least one universal link.

Soak those bolts down with pb blaster, preferably the day before, then maybe right before you do the job, and maybe even run the engine to get the bolts warmed up (just be careful the pipes will be hot).

A breaker bar might not be a bad idea.

The drivers side can be a little finicky getting sealed up properly, notorious for small exhaust leaks there if you can't get a tight seal.

Not a bad or difficult job unless you run into trouble. Worst thing you can do on this job I think is burn yourself if your exhaust pipes are still hot and even worse would be rounding off the bolts if you are not careful.

With hand tools and on Jack stands for a first timer I say probably 1.5 hours.

Awesome thanks. Good idea on presoaking the bolts a day before. Guess I need to go buy some extensions. Does it matter what kind? And I don't need to buy any sealant things rigt?

It's easy. Just need about 8 inches or so in extensions and then a swivel socket like mentioned. Getting the stock pipe off is the hardest. Aftermarket is so much easier, especially if it's Catless. First time took me a few hours. Now it takes me more time to jack the car up than take off my exhaust and re install it.

A lot of shops around here won't install due to it being illegal.

And yeah I sorta figured it wouldn't be too bad but just need some special tools. I'm assuming these can be picked up at harbor freight?

Yeah you can get the extensions and swivel joint from Harbor freight. Also if I remember correctly a deep socket is necessary.

Don't forget about gasket on passenger side, if your new h pipe didn't come with one pick up a new one preferably oem.

Also I'm not sure on your particular h pipe as I am not familiar with it but you might need o2 extensions for the rear sensor.

Lastly a tune to turn I'd rear o2s or mil eliminators. That or just drive around with your CEL on.

Gaskets need to be bought online I'm assuming? It probably didn't come with one. You can't reuse the stock one?

I have reused the stock gasket before but that was when taking stock mid pipe off to replace the clutch. Stock cat back went back on with stock gasket. Not sure about using it with after market mid pipe though

Gasket is the same, you can get them at any box store. Left side is easy, right side is a whore. Get a ball/socket universal, not a regular one. You'll also want to get a 1/2" drive socket set because a 3/8" set won't work on the right side. The shallow socket wont' grip the nut and the deepwell will interfere with the K.

Harbor Frieght is a real cheap way to get the tools to do this and they are pretty decent tools wtih a lifetime warranty. Same china stuff as the big box stores sell anyway...

Mac H Pipe Installation Tips?

I need

8" extension

1/2" ball/socket universal

3/8 deep socket

Swivel socket (is there a dimension?)

2 gaskets from autozone? What's their exact name because auto isn't going to know lol.

Making a list because I am not very tool savy, or anything mechanical savy. Shops won't do it around here though so I have to put this on myself. Here to learn




Please let me know if there's something I do or don't need. Thanks for the help guys

Too bad you can't find a Shop to do it. In Michigan almost every exhaust Shop will bolt them on. Cost me 75 bucks. You will spend that in tools and time. But if you have to you have to.

So surprise! Somethin had to go wrong. Imagine that. Lol....

Car has a welded in bbk catted x pipe. Most people wouldn't cry about a high priced mid pipe already installed but It's Not loud enough lol! The cats gotta be killin it. My car also had a stock muffler.. Who the hell puts a catted x pipe on a stock muffler?!? Has some flows on it now.

Anyways.. Now I am so confused on what to do. The bbk is rusted an prolly has little resale value. But the 170$ plus now the installation fee for welding and crap. No idea what I want to do lol. Any ideas or opinions?

First time I ever swapped my midpipe it took a few hours. The stock one is a PITA to work with. My Mac Off-road H pipe came in sections which made it stupid easy to install, with no cats there is a lot more room to work with, I don't even need swivels for it.

Takes about 30 minutes which includes jacking up the car.

The problem is one side is bolted like it should be, the pass side is welded to the piping that leads up to the mufflers. Not sure if I should replace that expensive mid pipe or not.. Maybe I can get a shop to hollow out the cats.. I'm so unsure of what to do. I hate returning stuff. Lol


Anyone got opinions I need some to persuade me one way

I guess my main questions would be - is the mac h pipe going to be a lot louder than the catted bbk x? If it will be then I don't mind swapping and trying to sell the x pipe.

I think the un-catted pipe will be louder and most likely be the sound your after. The install shouldn't cost you too much. They will cut that BBK out in minutes. It won't be too bad around me it would Maybe be a $200 job at most.

$200 if they had any issues removing the old one. I paid about 70 for my stock one to be removed and the o/r x installed. it will definitely be louder than it was with the cats, IMO it would be worth it. Even though you have the high flow cats they are still restricting some of the sound.

Alright I'll pay it if it's going to be worth it. I wonder if I can even sell the catted x for much. After they are going to have to saw it off where it was welded at.

As long as they don't mangle it, you should be able to get something for it.

Finally got it welded on by a shop for 95$. Not bad

and holy **** I now know why people said they could wake their neighborhood up. This is loud as hell and I only have flows on, I couldn't imagine slp's.....

I am blowing a little more smoke (gf said bluish) and of course it smells more which I already knew about.

Should the smoke be a concern? Or are they just breaking in? I know the mac's silver paint would rub off on my hand when I held it so I'm wondering if it is being burned off in a different color. Is more smoke common with a mid pipe? Or is this just a underlying problem that the car has had but been masked by the filtering cats?

Mine will smoke a little when I'm making an exhaust video (big revs to redline). I think that's pretty normal without the cats on. I think if it's not a bunch of blue smoke or continuously smoking when fully warm, it's okay. If you have a ton of miles, check your oil frequently and see if you smell or see radiator fluid or signs of water. If you see that, then you need to get your head gaskets replaced. I think that can cause some smoking too.

Only white smoke is coolant. If his is blue then it's related to oil. Should be fine unless it's blowing a lot of smoke.

Yup, and if it does it often, you can do compression checks on your cylinders to see if the oil is getting past seals, piston rings, etc.

Also, if it more like black smoke, that can mean it's running kinda rich.
