Review & Install Video

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.

    Get the job done.

    Have these on my built 02 GT. They fit well but need prepping to make them even better. Remove all the useless black paint and coat them with VHT ceramic high heat. They have been on my car for a while now and take a beating. Look Like the day I installed them and perform outstanding for the price. Plan on getting them again for my mod motor F-100 I'm building and doing the same. Warning Do not buy those flowtech headers! Those things are junk and are designed to have an exhaust leak on the left side header. Pacesetters are a one piece design unlike those flowtech garbage.

    Great for the price

    Bought these headers along with the shorty x pipe. Installation wasn't bad and they sound awesome. I can totally feel the extra horsepower as well. As far as fitment they're fine but I couldn't use my egr with these headers which is no big deal I can delete the check engine light with a tuner. I also don't know why they come black because the paint burns off within a day or two of driving. For the price, these are overall GREAT A

    Longtubes worth the install pains!

    Once they're installed you'll love them! But I had my Mustang guy install them with the matching Pacesetters midpipe. I have a tubular K so it wasn't as difficult as it may be but he ran into these issues: Broken studs off in head, took two extractors and a good hour. Bending dipstick tube. Had to guess and tweak it off the motor. Then test fit. But once on and I purchased some slightly better clamps for the collectors, and the sound and extra 30 HP and tq from the butt-o-meter were worth the labor cost.

    A word of caution

    If you're going to buy these headers buy this as well "SR Performance O2 Sensor Extension Kit - Pair (86-09 All)" at the same time and do it right. The extensions that come with the headers is 1 long wire and a bunch of crimp connectors. The extra $21.00 and change is well worth the price.

    You buy cheap you get cheap

    These longtube pacesetter headers had a horrible fit. I recently purchased these to replace my rusted out bbk longtubes due to a mean exhaust leak. I rather have kept the leak than put these on my stang! The egr valves do not line up one bit. They are a solid 1 1/2 inch off from each other. For now I have to plug my egr valve until I can get something fabricated. That is if I can find something in that size and thread to plug it. And if you aren't discouraged enough about these headers, the pacesetter techs aren't very helpful and don't have a custom service attitude. Don't waste your time or money. Buy a different brand.

      We haven't heard of anyone having these fitment issues previously, which makes me feel you may have received an incorrectly machined set unfortunately. Please give our customer service a call when you have a moment, so we can start helping you get this situation remedied as quickly as possible.

    Headers have great sound!

    Overall Pacesetter made a good product at an affordable price. On my 2000 Roush they idle quiet but at WOT they scream. Great sound and no issues with fitment. I would suggest coating them in heat paint or heat tape. After 4 hours drive time the black coating was already peeling from the heat

    Bang for the Buck!!!

    If you don't care what finish if on your headers because you can't see them anyway....then these are for you! If you have a custom fabbed midpipe where you are going to weld together the exhaust anyways...then these are for you! If you don't feel the need to waste hundreds more on a possible 1 hp more difference....then buy these! Fit is perfect..no bending..no banging....no hitting with a hammer..went on like a glove..be sure to use OEM ford manifold gaskets...dont chance it and use the flimsy paper ones that comes with the headers. Put these on my 2001 Bullitt...good feelable gains in the top end. Great sound with my custom bent H pipe and mac catback.

    Can't beat it

    Got these headers along with the shorty x-pipe. Already had pypes M80 mufflers installed and sounded good, but now that I've added theses headers and x-pipe...OMG! Sounds amazing, not to drone and when you crack in on it you will certainly turn some heads. Really good performance gains and can't beat the price. Don't pay more than you have to just for a brand name.

    You can still remove starter for new clutch install and transmission comes out with a little rotating. Really lets the engine breathe now and opens up the sound alot! Definitely get a tune tho after install because idle can be a bit strange at times along with a nice service engine soon light.

    I am happy with my purchase! AM was great and shipping was fast as usual. I didnt intend to spend $600 for my local shop to put these on, but it was the cheapest quote I recieved. If you already have an x pipe your much better off buying the pacesetter x pipe to go with these headers. The shop i had do the work had to do alot of fab work to get everything to fit the right way. Overall instal was pricey but the product was great and so was AM's service.
