More Power and Sound. This SLP system includes SLP's infamous Loudmouth "shotgun" race resonators that offer virtually no exhaust flow restrictions to free up more horsepower and to produce the most aggressive sound possible. Modular Design.   SLP's unique modular design allows you to quickly and easily switch out the mufflers or resonators to suit your driving needs. Along with the included resonators, the Loud Mouth system is compatible with all SLP mufflers and resonators including the bullet-type Loud Mouth II and the traditional-style PowerFlo Muffler.

Superior SLP Construction. This SLP Catback system is made from mandrel bent 2.5" 409 stainless steel tubing for its excellent non-restrictive flow characteristics and long life. The system ends with a brightly polished 304 stainless steel 3.5" tips, that are electro-marked with the distinctive SLP logo, giving a great finishing touch and a show quality look.

Application. Designed to be a direct bolt on, this SLP Loudmouth catback will bolt straight up to the factory Mid-Pipe without any modifications required on the 1994-1997 GT or SVT Cobra Mustangs to give it a rich, throaty sound.

Fantastic product. I paired it with a Bassani Catted Stainless Steel X pipe and it is thunderous. It isn't too loud, it doesn't have an interior drone like the Flowmaster series, all the noise is out back.

  • This exhaust should be bolted into the same location as the stock exhaust, so as long as your stock doesn't hit this shouldn't

    97 cobra

    March 03, 2010

    Fantastic product. I paired it with a Bassani Catted Stainless Steel X pipe and it is thunderous. It isn't too loud, it doesn't have an interior drone like the Flowmaster series, all the noise is out back. The Tips are a little gaudy for the SN-95 stang, so I might get different ones. It sounds like a pure muscle car now. My father has a bassani X and flowmaster 40s on his 97 cobra and with the bassani x and the SLP on my 97 cobra, they truly do sound very different but you KNOW its a cobra. Very happy with the shipping too. Arrived fast.

    SLP LM1

    June 25, 2010

    i recently got some SLP lm1's and what can i say they are a beautiful sight :P i was afraid they were going to be TOO loud, but they aren't. that is with my stock H pipe that i am still running. I am now debating with getting an offroad H or X and im not too sure just as to how loud it will be. any incite if you or a friend is running o/r midpipes to lm1's? that would be great. over all amazing product. the tips are massive and look great

    this exhaust really amped up my 95 GT. On top of being loud and sounding like a beast, as my wife says, it was easy to install...only took me a friend about 2 hours to take off the stock exhaust, drop the back end, and put on the catback....thanks AM!!

    Very happy with this product. Very good quality & fit... the sound is great. Good look and sound for my Stang. In my opinion, its louder than my old FM exhaust with cated H-Pipe. I have this paired with the Pypes X-Pipe street legal system and was able to pass emissions. Thanks AM

    This is an amazing exhaust. I didn't think it would sound as loud as it does. It is not raspy at all and fit perfectly. Thanks A.M.

    SLP Exhaust
