Features & Details

  • Increases Horsepower and Torque
  • Long Tube Header Design

More Horsepower And Torque. Now you can improve the performance of your V6 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 manual transmission 2001 to 2004 Mustangs equipped with either 3.8L or 3.9L V6 engine. 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.

BeaststangV6

  • Unfortunately, these will not fit properly on your 1999 V6 as they are made specifically for 2001-2004 V6 Mustangs.

Says these are for a manual but would they work on an AUTO. If not why wouldnt they fit in an Auto car?

TTV6CONVERT

  • The PaceSetter 1-5/8 in. Black Long Tube Headers are only designed for manual 01-04 V6 Mustangs. There is not enough clearance for the Headers because of the bellhousing and transmission.

will this work on my 2002 with the pypes true dual off road exhaust or do i need shortys?

anon123

  • The Pypes True Dual Off-Road exhaust comes with a stock length X-Pipe that has removable downpipes. There may need to be some custom modification done to properly set the long tube headers up to that X-Pipe.

On late model restoration the staff told me that these would fit my 99 v6 but I wanted to search around and see if I could find a different price. Now I see these but you guys say they don't fit the 99 v6. So who should I believe?

VincentT

  • hey Vincent, Unfortunately they would not fit the 99 v6. Directly from the manufacturer these only fit the 2001-2004 v6 mustangs.

    Really let down by Pacesetters

    First of all - I wana start off by saying that I love americanmuscle.com. I've been a customer for several years & have always been satisfied with every transaction. With that said - I'm kinda disappointed to see AM selling these headers. The install is a nightmare! Driver's side went in pretty smoothly. Passenger side just doesn't seem like it was designed to fit with the stock k-member at all. I tried almost everything outside of pulling the motor... it. just. wont. fit. =( So I go ahead & fire it up anyways with a shorty on the right & a longtube on the left (just for kicks. lol). In less then 2 minutes, the black powdercoating started to crack/burn/peel right off. Looks like absolute garbage now. Long story short - I am very disappointed. I wish I had just spent the extra $ & picked up a set of MAC LT's instead. I hear they have little to no fitment issues.

    Best Headers!!

    I am very happy to purchase these pacesetter long tube headers. The installation was not bad, it just takes time. These headers are the best mod for a v6 mustang because they add a good amount of horsepower and torque. I am also pleased because these long tube headers make people look at you and also get compliments daily because they are loud and have a nice muscle car deep tone. Overall I am very pleased to buy these headers from American muscle because they are a bang for your buck and also gained a good amount of performance at a fantastic price.

    From v6 to...BEAST!

    Although these are my first set of aftermarket headers ever, with shop installation kinda high due to fitting, and low hanging clearance...these Pacesetter's are worth every penny! Topping off my CAI, TB, SCT 4 bank, and off road duals with Flowmasters...not only do i feel the hp gains during mid to high end launch...i definitely HEAR it too!"THROATY".."PUNCHY".."NUTS"..is how a few people describe my 04 now...THANKS AMERICAN MUSCLE!

    Excellent

    These long tube headers are awesome! They have amazing airflow and make your car sound like a beast. The only problem I had is the install. The passenger side you can't just fit the headers from the top or up from underneath your car. You have to move your transmission to the left by unbolting it. Causes a little stress and problems but once you do that it's a breeze. But overall amazing product.

    PaceSetter Long Tubes

    Product fits well, it also sounds good and gives you that power increase! i ran some Magnaflow along with these LT's. It really gave me some power back that i had lost.

    Pacesetter Long Tube Headers

    Bought these headers a while back, and before, the fit description said it will fit on 01 -04 mustangs 3.8L and 3.9L with automatic transmission took the car to various shops and none could get them to fit i gave up and the headers are just gathering dust in a shed and now they've changed the description to Manual transmission only. No wonder I could never get them to fit. If I new they only fit on Manual transmissions I would have never bought them. I bought from from this website because it seemed reliable and trustworthy compared to all the others. But now I'm beginning to doubt American Muscle's website.
