Review & Install Video

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.

H-pipe? Is there an H-pipe that will fit this or is it just the Pace Setter X-pipe? I'm wanting to go with an H-pipe to get the sound I'm looking for

TholomewPlague

  • Currently, there is only the PaceSetter Shorty X-pipe that is designed as an exact bolt on. If you want to get a different brand H-pipe, you might be able to install it but some modifications might be required. If that's the route you want to take, I'd highly suggest contacting some local shops and find out who would be the best at helping you with the custom install prior to purchasing. Hope this helps!

Will the steering shaft rub on these headers? Ive got pypes headers on my 2002 gt and it feels like im trying to drive a car without power steering.

Pritch

  • Pritch Just about very brand of headers out there, are designed with steering shaft clearance. Physically check to see if there IS contact with your headers. If there is. Check that the headers are the proper model for your application. f there is NO contact, check the power steering equipment, and steering assembly. Duke7

Gaskets?? How long do the gaskets last?? any problems with them besides being thin??

2stepmsd

  • 2stepmsd The best answer that I can give you is... If you are going to put any aftermarket exhaust manifold on a modified street vehicle. Then use the factory exhaust gaskets that are designed for long term. If it's a race engines that gets taken down frequently it won't matter. Duke 7

    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.

    Best bang for the buck! Much better design around steering shaft without crimped tubes and sacrificing performance. Installation easy with aftermarket k member. If you are using EGR it will require modification.

    Had these professionally installed, took about 14hrs, thank god I didn't charge me for all the hrs. Paired this with the pacesetter o/r xpipe and flowmaster 40's and OMG!! talk about smiling from ear to ear. Sounds awsome and pulls a lot harder. Would def by again

    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.

    • Response from AmericanMuscle

      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.

    These headers are great! Fitment was 100% perfect. Price is what got me to buy these and I have no regrets! As long as you don't care about how they look then you've got nothing to worry about. I would highly recommend these to someone on a budget looking to do headers. They also come with an o2 extension kit.

    Great new sound and throttle response

    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. Great product make sure to get pacesetter off road x pipe it's a must!

    Be ready to pay alot for installation!

    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.
