Description
Dyno-proven RWHP Gains. Get the most power out of your GT with a set of SLP Long Tube Headers. These SLP ceramic coated headers will replace your restrictive stock factory manifolds to improve your mustangs exhaust flow and increase your Pony's horsepower and torque. Increases of up to 15 RWHP have been seen when installed with a matching SLP shorty X-pipe.

Aluminum Ceramic Coating. SLP uses a durable Aluminum Ceramic Coating on its long tube headers to reduce under hood temperatures, increase horsepower, lengthen the headers life, and for it's outstanding good looks. Ceramic Coated headers will long out last both polished and chrome plated headers.

Made In The USA. Hand-crafted right here in the U.S.A from 1-5/8" mandrel bent 409 stainless steel tubing, these SLP Long Tube Mustang Exhaust headers feature venturi-style velocity collectors to optimize exhaust flow, resulting in a monster increase of horsepower.

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

Application. These SLP Ceramic Long Tube Headers are designed to fit the 1996 to 2004 GT Coupe and 2001 Bullitt Mustangs with manual and automatic transmissions. SLP recommends using their SLP Shorty X-pipe for a perfect fit and the best performance gains possible.

Technical notes. Not legal for use on pollution controlled motor vehicles; intended for off road use only. Convertible models will require modifications to factory K-member cross brace.

I have an 03 auto and they still fit even though it says manuals, and unlike the MAC headers that I had to send back they did not hit the transmission pan, not really louder but they have a deeper ton

Awesome Product

I have been running these for 4 years now and they show very little sign of corrosion. Big power gain on my 98 GT mated with a SLP cat back and o/r x pipe. Only bad thing is this becomes the lowest point

Will these headers fit my 01 stang auto trans and do yall sell a O/r mid pipe that will fit these headers. I got a 2001 mustang gt automatic transmission and i was wondering if american muscle sells a Off road mid pipe that goes with the SLP long tube headers. I see in the drop down button it offers the catted mid pipe but i wanted a O/R mid pipe for automatic transmission.

  • Yes, these Long Tubes will fit on your automatic 2001 GT without any problems. Unfortunately though, we only carry the SLP Catted Mid-pipe to match up with these SLP LTHs. You want to use the same brand LTH as Mid-pipe to ensure proper fitment so I would not recommend combining these headers with another brand mid-pipe just for an O/R pipe. Hope this helps!

  • No it will not fit.. The 98 cobra has a 4 valve DOHC engine, much different from the 2 valve SOHC. So no they will not work.

Does American Muscle sell a Off Road mid pipe for a 2001 mustang gt automatic transmission? I currently have Shorty headers on my 2001 mustang and I want to upgrade to Long tube Headers. I seen that the only Long tube Headers in stock that would fit my auto trans is the SLP long tubes. I do not mind buying any kind of Long tube headers as long as it fits my auto trans, but My problem is i don't want a catted mid pipe and i want a off road mid pipe, but The SLP long tubes only come with catted mid pipe. Can american muscle help me in my problem. I want Long tube headers with a O/R mid pipe and i don't see any O/R mid pipes i can choose from. The only long tubes i can choose for auto trans is the slp long tubes but that comes with catted mid. is there a way i can get a O/R mid pipe with any brand long tube headers for my auto.

  • We also offer the PaceSetter Long Tube Headers that would fit your 2001 GT automatic. The shorty mid-pipe we offer to mate with these LTs is an off-road shorty. I've included the links for both below! Hope this helps!

    bitch to install but worth it

    first off get your friends together with an engine crane and a lift then slap these headers on. Install is a nightmare but once you get everything out of the way it goes pretty smooth and the finished product is well worth it tons of power and lots of noise.... perfect

    another great product from SLP

    The long tube headers are great they look good sound good and one of only a few items i have installed that I could really feel a difference from! Coupled with the catted X pipe, and loudmouth exhaust makes for a real race car sound under full throttle. I was very pleased overall. The shop had fitment issues, however I am not sure that the headers were to blame.

    Leaks

    I didn't want to mess around with the install myself, I knew what a chore this can be. I happily paid to get these installed. Still battling exhaust leaks between the header and cat. Was told the emblem on the header collector inhibited a perfect seal for the band clamp. Haven't had a chance to look at it myself yet. Slip fit exhaust is typically a pain.

    SLP all the way

    Wanna talk about a difference!? these long tube headers along with the SLP x-pipe really deepened the sound of my car. Sounds so aggresive now. Well worth the money!!

    Good Sound Change

    SLP is known for their drastic sound changes and for making good power. From the sounds of it they've achieved that here and for the feel of it i do have some more high-end pull. Install was as fun as any long tube is, but doable with the right tools and time.
