More Horsepower and Torque. Now you can improve the performance of your GT 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 1-3/4" 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 2005 to 2010 Mustangs equipped with the modular 4.6L V8 engine, including the GT and Bullitt models. These Long Tube headers will require the use of a shorty style PaceSetter H-pipe for proper installation (See drop down option above).

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

What X-pipe can I use with this? I'm looking into these headers but i want an X pipe instead of the available pacesetter H pipe. What X pipe is compatible with these headers?

MMGamez Year: 2005 Model: GT

  • Most long tube headers for your model will all be the same length, as well as shorty x-pipes. If you're going to use another brand, just make sure that the sizes of the pipes match, and that the x-pipe you're looking at getting is the same length as the h-pipe they offer. Best bet is to always contact the manufacturer and see if they offer the x-pipe at all, and if not, a list of compatible shorty's. That way you have someone to blame if it doesn't work. Just to be safe, I always contact AM directly and the manufacture of the product.

Do i need to replace the cats ? hello I have a 2010 gt with flowmasters and I was wondering if I need to change the pipes settings on my car can I keep the stock cats or do I need any modification ? thanks in advance

  • I'm not sure what you mean by "pipe settings" but if you wanted these headers, you would need a shorty H or X pipe (catted or not). You cannon re-use the stock cats.

    I bought these along with the FlowMaster cat-back system. The headers are 3” at the end of them and the FlowMaster exhaust (if you cut off the 2.5” reducer on the X-pipe) is also 3” so I have a 3” setup all the way to the back of the car. This has to be one of the loudest exhaust systems that I have heard short of race cars and demo-derbies. I ran it with open headers for a few minutes and after the FlowMaster install the sound didn’t change much; all it did was tune the insane loudness, which I’m happy with. At low RPM it has a deep rumble but anything over 2k it sounds like the engine wants to jump out of the hood. I don’t have any other engine modifications except for a K&N filter, ha ha. So this is as close to stock as I’ve heard anyone talk about and it still sounds amazing. I still need to have it tuned so I can turn off the rear (downstream) O2 sensors due to the check engine light and so it can be tuned to the whole new system and possibly get some more horses out of it. I’m also not sure of any performance gains as of yet. I haven’t noticed anything significant from driving it around. Don’t buy these for the black paint; I kind of did because my Mustang is black and AmericanMuscle bills it as “providing an aggressive appearance to your engine bay” but less than a few hours after install the paint burnt off and the pipes are just a funny looking silver now and would probably rust if I ever drove it in the rain but luckily I don’t. Sometime during shipping one of the headers got a dent in one of the cylinder tubes. I don’t blame the shipping company; AmericanMuscle did a terrible job of packing it. The two headers were put in an oversized box with some brown paper for packing but not nearly enough. I’m just warning you ahead of time that this could happen. I already had the car up on jack stands and the old exhaust system off when these arrived so I was not sending them back and waiting a few weeks with my car out of commission. All in all I’m happy with the whole set-up and would recommend it to anyone who wanted to make their car quite loud. I was told by my roommate that he could hear me from over a half mile away…with a forest in the way so this system is not for someone who is afraid of getting pulled over by the police for noise violations…not to mention that you won’t have cats either when you get pulled over which I’m quite sure is illegal in every state. The video I attached is just to illustrate the loudness of the system. The first part is on the outside and the second part is from the inside up to about 120 MPH in fourth gear with the windows shut. The third part is just showing there’s no drone sound at 80 MPH. I also have no problem talking to anyone in the passenger seat while riding along…however; I can hardly hear myself think on takeoff. :-)

    Bang for the buck is an understatement

    The primary size was right as was the collect size and style. The only draw back was they are only available in steel, for the price I ordered them and shipped them to JetHott as soon as they arrived. End up with a great pair of headers for less than a set of SST with better performance. As for the fit, they were perfect one of the best fitting pair of headers I have ever put on and I have dropped so serious cash on high end headers in the past. Buy them, Coat them, Can't go wrong.

    Pacesetter Black Long Tubes

    I was lucky to have access to a lift to install these. It took an entire day and some creative lifting of the engine. The instructions from BBK worked but you had to improvise a few places. We ended up removing both motor mounts and all the steering connections around the motor. I used Ford Racing gaskets instead of the ones supplied. These fit very well and looked like better quality than the ones provided. The car smoked like crazy when we first started it from the paint burning off. The paint was all gone within 100 miles. I show my car occasionally and the detail spray has caused a little bit of rust. It will wipe off. Don't buy these for the finish. We did not put the cats back on and man is my car loud now. I have a Bassani X pipe with Flowmaster American Thunder mufflers. The drone is minimal and I can still hear inside the cab at cruise. If you lay into it, everyone within a mile will know it. When I am at the strip you can definitely hear her coming! The car sounds like a MONSTER!! The performance gain was not as much as I had hoped. I had it dynoed and it picked up about 4 horses from our last trip to the dyno. You can feel a difference though even if it doesn't show. The downside to these is that the new bolts supplied are starting to back out and I have a horrible leak. Go ahead and order a set of locking header bolts when you order these. Overall for the price these headers are a great deal! Sounds awesome and a gain in power and better throttle response for half the price of others.

    Good Set of Headers

    A lot of people have already mentioned the paint. It sort of sucks that you have to strip all that paint off just to run them bare or paint them all over again, but that is a place where the company saw they could make some money. Installation was easy up until the driver's side. Take your time to make sure you aren't beating the heck out of them and everything goes together well. Worth the money. Oh, and if you were thinking about an X-pipe, be prepared to pony up a little doe to have them custom fit, as these are not meant to line up with anything but Pacesetter mid pipes.

    You get what you pay for.

    The fitment on these headers are pretty bad, but at a third of the price as the Kooks setup what did I expect? Took my Mustang shop 2 full days to get everything to lined up and once they put the car on the ground the steering shaft bolt still hit the headers bad because of a not so good design. That being said once they're finally in and aligned they are fine, sound great and are still one he*l of a bargain but just be aware of what you are getting into when purchasing these headers and Hpipe.

    Great price, Great sound, Can't go wrong!

    Definitely a good aggressive sound for an aggressive price! I got the O/R H-pipe paired with Bassani mufflers. Performance was acceptable. It gave it a good increase in throttle response. I did experience trouble fitting the H-pipe over the header. A piece of advice for someone who might have this issue in the future. TORCH EM!. If you have access to a torch, it will make life easier. My buddy (who had this genius idea) and myself heated the end of the H-pipe nice and hot which expanded it enough for it to slip right on! Hope this helps some of you and prevent anyone ready to take a hammer to the H-pipe! I am overall satfied with these headers and would reccommend them to anyone on a budget like myself. I had access to a lift which made things a lot easier. Still a time consuming project, but the many hours and busted knuckles were well worth it!

    Product could be better

    This is no reflection on AM. You guys rock. As far as bang for the buck, you can't beat it. However, for fit I gave it an average. I bought the Pace Setter h-pipe to go with this, but we had to expand the shorty H tubes so they would fit inside of the LT's. It wasn't fitting properly until I did so. I understood it would be a great fit but wasn't. In addition, they sent one wire to extend the 02 sensors manually, but ran out on the first one. thirdly, the wire caps were enough to cover two 02 sensors but not all 4. I found some additional wire at the shop, but just ordered a the 02 extenders for the front sensors to save time and headaches. Fourthly, The gaskets were a joke they sent. I ended getting some R4 and using the existing ones. Lastly, as most folks already know, don't expect the black paint to last on it. Honestly, I should have spent the extra bucks for a higher quality LT.

    decent for the money!!

    I think these headers are very acceptable for the money when your referring too the fit, power gain and sound. But not for the paint. I stripped the paint off the headers and re-painted with high temp paint and they look good now!

    The Sound I've Wanted

    I put these on my 2008 GT. First thing I did was take them to get them ceramic coated since all the other reviews said that the finish wouldn't last. Thanks to all the others who commented to tell me that! So, mine look great too! If I would have shopped around a little, I would have found this set already ceramic coated on another website... oh well! I bought these headers in preparation for the Ford Racing Hot Rod Cams. I'm not a professional driver, and the car that these are on only gets driven about 2,000 miles a year, so I don't notice a huge performance increase. BUT I do notice a huge increase in smiles per gallon. These headers have given my car the sound I have wanted since I bought the car four years ago. If you want your little 4.6 to scare away the Camaro or any other competitor, get these! If you love to feel your car in your chest when you drive, GET THESE! If you like that sudden neck snap when you mash the gas, and you want your pony to stand out from the herd, you have got to get these. I would also suggest a custom tune. I drove it for a while before I loaded the Tune, and the sound before was not as refined or nice. I tried to upload pics, but since mine are ceramic coated, not sure if they will post. I hope you love yours as much as I love mine!
