Hey guys. Stephanie with AmercianMuscle.com, here with my review of these long tube headers from Pacesetter available for 1996 to 2004 GT Mustangs. These Pacesetter Long Tube Headers are going to be the perfect option for those guys out there that are looking for a set of long tube headers for some performance and sound gains, but that are on a serious budget. Picking up a set of long tubes means a mid-pipe as well and possibly even some tuning expenses. So it can get pretty expensive, pretty quick. These headers have a one and five eighths-inch diameter, and they're one-piece flanges as well. Getting into some of the specifics here, the first thing you're most likely noticing is that these are black. Now this is black paint, it's not any type of coating that's gonna help with heat dissipation or power or anything like that. Pacesetter does this solely to protect the headers when they're in storage and during shipment, but it's also gonna create a different feel in the engine compartment as well. If you're building more of a show car that has a little go to it, you might want to check out some of the chrome or even the ceramic-coated options since they might suit you better. But if you're just looking for some power and more sound out of your car, and you're not concerned with appearance then stay tuned. These have a 16-gauge carbon steel construction and they are mandrel bent which will help with smooth airflow. The header flanges which I mentioned earlier are CNC-machined and they're three-eighths inch thick, so that's gonna give them some additional strength. One thing I will say is that when it comes to long tubes well a tune is not required, it is always gonna be your best bet when you switch over to your long tube setup. Now I say this because a tune will not only help you get everything out of these expensive mods, but one of the main purposes of the tune with long tubes is to turn up the rear 02 sensors so you won't be getting a check engine light. Now if you really don't want to tune or it really isn't in the budget, since we are talking about budget shopping at this point, then you can get away with running some MIL eliminators to get rid of that check engine light. If you didn't know already, when you change your header setup to a long tube setup, you also need to change your mid-pipe to a shorty mid-pipe to work with the long tubes. These headers are specifically designed to work with a Pacesetter shorty mid-pipe. The Pacesetter mid-pipe is an X-pipe, so you know you can expect a louder, raspier sound than you get from an H-pipe. One thing I will say is to just know that when you're shopping on a budget, you might notice a few little sacrifices that you end up having to make. A lot of times, it's come down the form of fitment issues and the budget from the option often times don't have some of the nicer features like scavenger spikes or nicer collectors. At the end of the day, though, these aren't necessarily things that are essential to the header's function, so if you can live without them, then it's a go. That leaves me to the price of these headers, as we all pretty much know, or you know if you've been shopping for long tubes, they get pretty expensive. They are pricey, and they're difficult to install. The Pacesetter Long Tubes are priced much lower than any other option on the site. You'll get under $300 for this set right here, and the corresponding shorty X pipe that you will need with these is under $200. So in total at the end of the day, you're looking at under $500 for a set of long tubes and a shorty mid-pipe. Two tips I will give, however, is that I have heard of this black paint coating peeling after the headers have had some heat ran through them. If you want to avoid this peel, you can always coat the headers yourself or even wrap them if you want to. If you don't mind the looks at all, then you don't even have to worry about it. The other thing that I wanted to point is that while these do come with gaskets, I would highly recommend picking up a set of Ford gaskets for the install; they're just a hardier, better gasket. Either way, at the end of the day, you're looking at both power and sound gains here. Any power gains will change depending on your exact setup and tune situation, but usually you can expect some top-end gains with long tube headers. And in addition to that, you're also gonna get an awesome change in your exhaust [inaudible 00:03:21]. As for the install on this one, long tubes are always gonna be a difficult install, I don't say this often, but if you don't have a helping hand or you don't have much experience, it might be better to just take the car to a shop for the install. If you do tackle this yourself, it's gonna be a full three out of three wrenches on the scale and a day in the garage, especially considering you will be installing a mid-pipe with these headers. You can do it on a jack and stands but doing this on a lift would make it easier for sure. You're gonna need your toolbox for this one with an assortment of different sockets, wrenches and extensions. You're looking at things like disconnecting the steering shaft, the starter and removing the motor mounts to get enough room to do this. A lot of the install obviously requires working in some pretty tight areas, so while everything is straightforward, getting access and maneuverability in these areas is actually tricky. To make things easier, you're even looking at pushing the trans out of the way to get enough room and having a helping hand in this case is really going to benefit you. But a day of rustling and some pretty penny spend on these mods is totally worth it in the end. So wrapping things up here, the Pacesetter Long Tubes are one and five eighths diameter, they're designed to work with the Pacesetter shorty mid-pipe, and they're gonna offer both performance and sound gains. This option is as budget-friendly as it gets, and the headers are painted black. You can check them out more online for yourself right here at AmericanMuscle.com.

More Horsepower and Torque. Now you can improve the performance of your 4.6L Mustang with a set of PaceSetter Black Long Tube headers for power you can feel throughout the RPM band. These Long Tube headers when combined with a PaceSetter shorty mid pipe will greatly improve your Mustangs exhaust flow for an increase in horsepower, torque, and throttle response.

Durable Construction. Manufactured from 1-5/8" mandrel bent 16-gauge carbon steel tubing for strength and unrestricted airflow, these PaceSetter Long Tube Mustang Exhaust headers feature CNC-machined 3/8" thick header flanges for additional strength and an OEM fit.

Black Painted Finish. These PaceSetter Headers feature a standard black painted finish, which is used to protect the headers during storage and shipment, as well as providing an aggressive appearance to your engine bay. This is not a heat-resistant coating.

Recommended Upgrade. To realize the full power potential that these Long Tube Headers have to offer, AmericanMuscle recommends a Bama custom tune with a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation.

Application. These PaceSetter Long Tube Headers are designed to fit the 1996 to 2004 Mustangs equipped with the SOHC 4.6L V8 engine, including the GT and Bullitt models. These Long Tube headers will require the use of a shorty style PaceSetter X-pipe for proper installation (See drop down option above).

Technical Note. This PaceSetter product is not legal for use in emission restrictive states.

Since AM no longer carries the Pacesetter Off-road X Pipe that was intended for use with these headers, will any other LT x pipe be compatible with these LTs? Thanks!

  • Unfortunately, the PaceSetter 1-5/8 in. Black Long Tube Headers do require the use of the pacesetter x-pipe which we no longer carry, at this time we do not have an xpipe compatible with these headers.

Max

  • Hello! Obviously it depends what you are looking for in the headers that you choose, however these will offer more power and a deeper louder sound than shorty headers.

    perfect part, perfect value

    Zero issues. Install was a pain, of course... but after a season of driving the headers are still in perfect shape. I sprayed them with high temp self etching paint... the top of the primaries... all that paint is blistered off... the bottom is still good.

    Best mod so far!

    I had every other bolt on caí, pullies, tb/plenum, cat back, 3.73 gears and tuned to 91. I left the long tubes for last and out of all the LTs were by far the best. I picked up the pace setters cause of the price and simple design. I had them installed by the family mechanic. Took two days to finish and once they were on it was just WOW! The sound is clean and drivability is perfect. This model of mustang should have come from factory just like mine is now. If you're on the edge of buying them cause of the price but worried about fitment/quality, don't worry the're a perfect match. Oh and not to mention the power bump, quicker at every RPM :D

    A direct fit on my 2002 GT

    Replaced my engine and might as well get long tubes. So I got these removed the black paint and sprayed them with VHT Header Paint. Then installed them with Original new Ford Exhausr Gaskets from the dealership and used factory bolts. The EGR tube was almost a direct fit just had to play with a little bit but it will get there. Then if your dropping the motor in the kmember just take the steering shaft bolt a size 13 out and push the shaft down and it should drop right in. But installing the transmission from under the car was tricky. You got to turn the transmission so you can clear the headers. But it will fit. GREAT HEADERS. Felt good amount of power especially at high RPMS.

    Passenger side header had an a slight warp about an 8th of an inch. Used factory gaskets instead of the cheap ones that come with it. We will see if it holds.

    Pretty great headers!

    black paint of course does all come off as expected after a few times heat is run through it. They sound monstrous and essentially just like any other long tube header on the market today. This took me a whole weekend to install just because of some difficult bolts and it being my first long tube header install, i ran into a few set backs that were unexpected. Great product and amazing bang for your buck, would definitely recommend if you want your exhaust to sound like a beast and pick up a little power while youre at it.

    The install was problematic. Not because of the headers, but because of the Ford design. Once installed it was music to my ears. Instant gain in UP. But needs to be returned. Good choice for any 4.6gt or crown Victoria!

    Well worth it!

    Install went pretty alright. Some parts were a huge pain. Specifically the top two middle bolts on the passenger side. Fitment actually went up really nicely but I had my motor mounts out at the same time because I was swapping them for static mounts. BUT the new bolts were the wrong size. That was pretty upsetting. I also sandblasted, primed and painted mine with VHT primer and flat white which I highly recommend. But you should to that a few days before because I had to wait a night for the paint to dry.

    Very pleased !!

    Installed the Pacesetter longtubes and o/r xpipe on my 96 GT. This car is not a daily driver so I just worked on it on weekends until it was done (also did control arm bushings and solid motor mounts while it was apart) and while it is a big job the results are well worth the time and labor. I have the CMS stage 2 cams in my PI swapped stang, and this new exhaust addition makes it sound awesome. Everything fit very well and the only mods I had to make was some machining on the exhaust flange to ensure they were perfectly flat for a good seal. I used BBK exhaust gaskets and not the ones included because I did not want to have to chase an exhaust leak.

    Just wow..

    Not sure about the other longtubes you can buy, but you have to love the "perfect world" instructions these come with, the only easy way to install these are to either lift the engine or drop the engine, the dipstick tube didnt fit back between the header, the midpipe most definitely didnt fit under the transmission brace, and the instructions saying nothing about having to install the steering shaft simultaneously through the headers. Ended up having to have a custom midpipe made to fit these without cutting into the floor pans, awful design on pacesetters part.
