    Video Review & Installation

    The MAC 1-5/8 inches Long Tube Headers in chrome are available for any '96 to '04 GT owners who's looking to pick up some noticeable power gains as well as a sweet sound improvement with one of the more affordable options in the long tube category. These are the chrome options as opposed to ceramics, so for the guys who don't mind the rainbow color after they run over time and for those who are on a tighter budget. The installation for the long tubes is extremely lengthy and heavily involved across the board. Expect three out of three wrenches on our difficulty meter which I'll talk a little bit more on later on. Long tubes are so effective in improving power because the exhaust gases leave the cylinder with more speed because they have more time to gain velocity, thanks to the longer tubes. With this particular set, you'll see results in gains of up to 18 real horse power and about the same with torque which is definitely a plus. We always want to consider that other power adders can really maximize the potential, not to mention the effects a tune would have on something like this for your GT, although it is not required. Sound is an entirely other aspect because long tube headers are absolutely unbeatable for a true muscle car sound, of course, in my personal opinion. This in combination with the MAC Shorty Catted H-pipe will produce a deeper intimidating growl while combining it with the Catted X-pipe will give it a bit louder and raspier sound. Any off-road pipe combo will be a bit raspier since there isn't any restrictions in the mid pipe with no Cats. You can customize the sound, though, obviously by picking and choosing a Cat-Back setup that fits your personal preference. Personally, I'm a big fan of the Borla Stinger S-type Cat-Back because it's not too overbearing but it really makes a huge impact on your aggressiveness as I've had on my '95 Cobra. Obviously sound is one thing that is easily changeable to each person. While we're on the topic of restriction, these are made from 1-5/8 inch mandrel bent tubing completely unrestricted and gets a free-flowing air movement from the cylinders to the MAC Shorty H-pipe or X-pipe of your choosing. The 16-gauge tubing doesn't have any kinks or rough bends to rob you of any power. You'll notice that the chrome headers will start to discolor after being exposed to the engine heat and exhaust gases for so long, so they'll start to turn a bluish rainbow color. Obviously, the chromes all across the board are going to be guilty of that, not just the MAC ones here. As far as performance goes, that is completely unaffected by the discoloration it's simply an appearance change. Although that doesn't happen with the ceramic coated set so if you're in a lot of car shows and you're looking to keep your engine bay looking as polished and proper as possible, you might want to pick up the ceramic version instead. If you're like me and you don't really care about the color and you just really want to save a few bucks by getting the chrome option here, this is definitely the better choice. The 2-1/2 inch True Fit Collectors that MAC integrates into the systems, as you see here, eliminate the need for gaskets that are sometimes needed with collectors of ball shapes and to properly seal the flare end of the mid pipe. Now, this takes away the headache of a leak or blown out collector. While we are on the topic of gaskets, I would recommend picking up a set of Ford performance header gaskets for the other end. They are known to be the most reliable options, more so than the ones typically found in long tube header kits you get from those brands just like MAC. Obviously not a hundred percent necessary, they just are a little sturdier than most. I also want to point out just again you absolutely need to match these with a MAC Shorty mid pipe of your choice but no other brands. Stock length mid pipes will not work with long tubes nor will any other brand of mid pipe. They won't properly match up and they'll require modification. Just make sure you stick with the Catted Off-road Shorty H-pipe or X-pipe from MAC when you're picking these up. As I briefly mentioned in the beginning, these are one of the most affordable long tubes available in the category currently for the SN-95s and new edge GTs. For just about $450 bucks you'll get a sturdy set of chrome steel long tubes that'll definitely get the job done. In my opinion, they are a steal for the price considering the construction and the materials. If you're more interested in the ceramic look, however, those are running just about a $100 bucks more than these. The Kooks option offers the best materials on the market with 304 stainless and they have a very unique sound with their added merge spikes but that comes with a pretty serious price of about double the MAC option here so it comes down to budget for sure. These are, no doubt, a pain in the butt to install because they are so involved and require a certain amount of mechanical expertise. They will definitely test the entire toolbox and take the better part of a day to complete whether it's at home or in a garage or shop. If you don't have a helping hand on deck or enough experience to tackle it yourself, there's no shame handing this one over to a professional to get them safely and properly which is why you might want to consider tacking on installation cost to the final cost of this product alone. With all that said, expect full three out of three wrenches on our difficulty meter. Several hours, if not, with the majority of the day, to get this one done. Also, before I let you go, you might want to look into a set of O2 sensor extensions if you're looking to stick with your stock sensors. If you're looking to eliminate to check engine light with a quick fix, you should invest in a set of MIl or MIL eliminators to plug right in which will take care of that itself. MIL being Malfunction Indicator Light. Or you could take it a step further and pick up a custom tune which would not only shut off the light but will help you bring out the best in your setup and maximize the performance I mentioned earlier. That, however, is not required. All right and that just about does it for this one so if you're the owner of a '96 to '04 GT, you might want to check out the MAC 1-5/8 inch Chrome Long Tube Headers which are available right here at americanmuscle.com."
