    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 Cat-Back 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 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.

    Will these fit on my bbk offroad xpipe?

    I have a 1998 gt, why won't it fit on my car? It says 94-97

    ConnorF

    • This SLP Loudmouth Cat-Back Exhaust was designed for the earlier 94-97 cars. Due to several revisions to the mustang in 1998, this is incompatible with the 1998. We do offer the SLP Loudmouth Cat-Back Exhaust designed specifically for the 1998 cars, linked below: https://www.americanmuscle.com/slplokit98gt.html

    Will this set up work with the bbk long tube headers and bbk shorty catted h pipe that you guys also sell?

    ShaneK

    • The SLP Loudmouth Cat-Back Exhaust will work perfect with BBK long tube headers and catted H-Pipe, as long as the H-pipe is designed to bolt up to stock cat back, because the flanges on the cat-back are engineered for factory mid-pipes.

      I installed this exhaust on my 96 Cobra. It's loud with a nice rich tone. Your neighbors are sure to hate you. Install was easy with a friend's help. I'd buy again.

      Amazing!!

      Sounds absolutely amazing!!!!! Not for those who are afraid of a loud car!! The great thing is that it sounds like a loud performance exhaust, not like I’m running straight pipes or something. Performance is also amazing, probably gained about 5-10hp over the regular h pipe/Flowmaster setup.

      Slp loud mouth

      Fit and finish was very nice. Install wasn't bad with a floor Jack and stands. Took about 2 hours or so , recommend not tightening every bolt until you have it hung and aligned . Looks amazing and the sound is the best I've heard on a mustang . Have BBK short headers , BBK x pipe with the SLP exhaust and you can hear it coming from far down the road. Couldn't be happier , nice aggressive, if you wanna be heard , get this set up. Thanks AM

      Excellent, but not perfect

      The cat back exhaust is excellent, great sound, although some rasp, the sound isn't too bad. Aside from them being super loud, they're a real head Turner. The "mufflers" and the tips were excellent, wrapped in bubble wrap and everything, but as for the actual pipes themselves, they were scratched and just didn't look like I was expecting.

      pretty good, they are what they are, LOUD!

      Love them, love the pops they make and love the sound when I hit the gas. Personally I don't like the top end of 3rd and 4th with an O/R X-Pipe so I am gonna change out for an H-pipe.

      The Loudmouth exhaust system is the best modification I have made to my Cobra. The sound is phenomenal and the 3.5" pipes look so much better than stock. I highly recommend this to anyone. You will love the sound!!

      Jackpot!!!

      I recently did a custom 302 build using a trick flow top end kit and a list of other parts which resulted in over 300 RWHP on the dyno. I needed an aggressive tone and after looking on a certain video sharing site, I came to the conclusion that SLP was going to be the best sound. I already had a BBK x-Pipe and Hooker Super Competition Headers installed. I had a local shop install the system just to avoid the hassle. When I picked my car up, I knew the SLP was going to be loud but I had no idea how loud and aggressive it was going to sound. I was blown away. Cold starts are LOUD! Loud enough that I let it warm-up and go inside for a few minutes till I hear the RPM's lower. Once the engine warms up, the idle is great; Very aggressive. Normal acceleration is LOUD and smashing the gas is EAR SHATTERING. Cruising at 3K RPM produces the most aggressive sound to ever come from a 302. I wouldn't use another exhaust system even if I was sponsored. When I go cruising on Sunday afternoons the amount of approvals I receive is amazing. Every Mustang owner also approves and tells me they plan on making the purchase as well. I've been flagged down by other SLP owners when out and heard the SLP LM1 on a couple stock 302's and can still claim that this is the kit to have on your mustang.
