    Hi, I was wondering if you could use another mid pipe like the BBK one other than the MAC mid pipe. Thank you, Chris

    • Hello, you will need the matching MAC mid pipe to go with these headers. The BBK Mid pipe will not work.

    Will the stock hybrid H-pipe work with these?

    doesntmatter

    • Hello! The MAC Chrome Long Tube Headers will require a shorty mid pipe to compensate for the additional length of the headers.

      Disappointed to say the least.

      I purchased this along with the shorty mid pipe back in Feb 2017. I installed them over a weekend to ensure everything went right and i didn't have to rush the project. At first i really enjoyed the sound of my car, but after a few months of driving it around i noticed the car has developed a metallic buzzing sound. It hurts my ears at times with how high pitched it can get. I got back under the car and everything looked in place, so I'm not sure what's going on. One thing i will give it is that it's for sure LOUD if you want loud this will get it at the price of annoying buzzing.

      I installed these in August, 2015. I wrote the installation guide. I ended up pulling these off my car within a month. Just like many others, I had a terrible rattle/metallic sound. I tried different cat backs, added resonators, but nothing worked. My mechanic said that they seemed really thin. I would not buy these and I am terribly disappointed in the quality of these. I waited this long to write this because I finally got around to selling these headers (for a $300 loss) recently.

      Pleasantly Disappointed

      After hearing the horror stories from many who installed themselves, I was leery to attempt this on my own. I did however, and from teardown to closing the hood when finished took me just at 4-1/2hrs. Not too bad for a shade-tree mechanic. Fit and finish were as expected. Very clean and looks well built. Now, the negative. I installed the headers in combination with the MAC ProChamber. I had already installed Flowmasters ABs about six months prior. On startup, the growl was nice and very audible. However, once I took it out for a drive, that growl turned into a nasty, raspy buzz between 2500 and 3250 RPMs. So much so, that I misdiagnosed that buzzy rattling as a loose baffle in my Flowmasters. I exchanged my Flowmasters for a set of GT Takeoffs. But, that buzzy rattle was still there. After taking my car to a highly recommended and very reputable exhaust shop, they diagnosed that buzz as something loose inside the ProChamber. While the ProChamber was sent back to MAC for inspection/repair, I had my factory catted x-pipe cut to fit for the LT Headers and cat deletes. Buzzy rattle is still there...so now I know that the unbearable noise is due to the LT Headers. I can only surmise that it is due to the thickness of the material used to make this piece. I have a feeling that at a certain RPM, the amount of air flowing through and the vibration caused by such, causes a reverberation in the tubing that is only amplified by the length of the exhaust piping. In closing, if I were to purchase a set of LT headers again, knowing what I know now, I would opt for a thicker walled construction or a coated set of headers. Maybe that would eliminate that awful buzz/rattle sound.

      As soon as I opened the box, you'll notice how good these look. As I installed them, I ran into a couple of issues. You might need to take out the oil dipstick to have an easy install, and move around some wires, but that is pretty much assumed. Once the 3-hour installation was over, it looked great. So much better looking under the hood. Now as for the exhaust note/tone, I have to say it is raspy without cats. I ran it with an off-road custom H-pipe for about a week and installed small resonators. This definitely cut down the raspy tone a bit. I do plan on replacing them with bigger resonators in the future, right now it sounds raspy when shifting above about 2600 RPM and when lightly accelerating above 2800 RPM. As for power, you can feel the difference right away. It just pulls harder throughout the power-band. The chrome finish has already shown heat discoloration at the start of the headers. This is expected with chrome and heat so it isn't a big deal. Installation was done with a friend so you can maneuver the headers into place. Overall, I would recommend these headers. You can't beat the price for what you get.

      Top and bottom slide in

      I bought these headers on thanksgiving for the Black Friday sale for over half off, and when they came in I was just to excited to not put them on. So I set to work on my lift taking the factory x-pipe off and setting it to the side. I then removed the factory manifolds and the the starter(battery disconnected of coarse) and the bar that is in the rear of the k-member then placed the passenger side header in through the bottom. It went right in, and using the factory gasket, I bolted it right up. Then I moved to the driver side. I lowered the car down, pulled the dipstick tube and it pretty much fell in from the top. I did have to pull the fuel lines a little to the back but nothing major. I then cut off my cats and had a muffler shop weld up pipe to the factory x going to the headers. I then went the same day and had it dyno tuned. It made 280.67 hp and 223.44 tq.(also have a c.a.i. and 3.73 gears). The only thing about the whole install and tuning was the o2's. You have to use the front two(I had the back two turned off) and the stock ones aren't long enough. So you either have to get someone to sodder extension wires into them or buy extensions. I didn't have time to wait on extensions so I had someone sodder them.
