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 1-3/4" 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 either a SCT SF3 or SCT LiveWire Custom Tuner.

Amazing!

These were an absolute perfect fit! The installation went beautifully and the shop said they havent done a header install that easy in years. They didnt even have to lift the engine to install them.

    LOUD!!

    April 05, 2010

    I was so happy with the SLP Loudmouths that I had to get the SLP Long-tube headers and the shorty X pipe. There is no words to describe the sound. Not only is it INSANELY LOUD, its really throaty and sounds meaner than anything I've EVER HEARD!! If your looking to have the loudest and meanest sounding mustang around this is the exhaust for you!!! It turns heads everywhere I drive. People ask me all the time what kind of exhaust I have and I proudly say SLP from AM! You guys ROCK!!!!

    good stuff

    August 07, 2010

    pretty straight forward install. some long extentions and swivel sockets prove to be worth their weight in gold. i would not do this install w/o access to an automotive lift. ( although its probably possible ) it will be necessary to shim out the dipstick tube with a 6mm x 1.0 bolt 30mm long and 2 5/16 nuts work well as the shim. combined these headers with the slp catted x with the stock mufflers and the sound is just wow. throaty when you want it and quiet when you need it. cant wait to upgrade my axle back set up

    These were an absolute perfect fit! The installation went beautifully and the shop said they havent done a header install that easy in years. They didnt even have to lift the engine to install them. I can definitely feel the power increase with the SLP catted X-pipe and SLP Loudmouths. SLP makes quality products with incredible sound and I am extremely happy with them.

    Awesome

    I purchased and installed the long tube headers, X pipe, and the loudmouth pipes. One word can describe them AWESOME. Had a little issue getting the bottom bolts in on the headers on the passanger side. Recommendation to SLP is t modify the headers and cut the center two holes out like the end two.

    Headers for life!

    March 21, 2012

    These headers rock. The SLP long tube headers sold me on the quality in which they are produced. Get ready for a sick sounding car! The headers make a great addition to the 4.6L really helping the car breathe better. Very strong and very high quality. I have mine coupled with the rest of the SLP package including, the shorty catted X-pipe and the SLP loudmouths. To say this car is loud is an understatement. I also cave a cam in mine and it turns heads wherever I go. The downside to these headers is how low they sit. My GT is already lowered and once in a great while I will hear the cats scrape the ground when I hit a big bump in the road or going over some kind of short hump. There is no good way to stop this other then being very careful. Overall, more than happy. 5/5

    Best long tubes money can buy

    June 13, 2011

    These headers rock! I already had the SLP loudmouth axel backs so it was time to get the rest of the exhaust done. I decided to continue to make my whole exhaust SLP. It does not disappoint! The install was to terrible but not great. A couple of pointers, unbolt the AC unit but do not disconnect. The passenger side is the hardest side to install on. The upper front bolts are very hard to reach. We did use ea lift. The sound is epic! It's coupled with the SLP shorty x pipe. It is the loudest Mustang in my city now. Beautiful parts, very well made. Well worth the money. 5/5

    Bad A**

    September 01, 2008

    I purchased and installed them myself and they were no easy task. However, if you install the SLP Long Tube headers with shorty catted x pipe and loudmouths, then your mustang will be the loudest in town. Not to mention the power boost you will get. They are definitely worth it.
