    More Power and Sound. This SLP system includes SLP's famous Loudmouth II "Bullet Style" race mufflers for minimal restriction, increased horsepower and an aggressive tone, that are only second to the Loudmouth "shotgun" race resonators for sound.

    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 bullet mufflers, the Loud Mouth II system is compatible with all SLP mufflers and resonators including the shotgun style Loud Mouth Resonators 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 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 as a direct bolt on, this SLP Loudmouth II catback will bolt straight up to the factory Mid-Pipe without any modifications required on the 1994-1997 GT and 1994-1997 SVT Cobra Mustangs to give it a rich, throaty sound.

    I am really on the fence about this exhaust. I have purchased Pypes M80, BBK Hpipe and Longtubes now. It is insanely loud with an obnoxious glass pack type crackling sound out of first, higher RPMs and WOT. I want something that flows but is a little deeper and more restrained in these situations. I have heard numerous clips but none with my exact setup and read the multitude of subjective reviews..I am asking you for another. Either this or I just go with a Magnafow catback (not Magnapack). Overall, deeper sound with no popping and great flow. Thanks!

    • This exhaust will definitely be deeper than the Pypes exhaust you have currently but you may still experience some of the crackling sounds with this exhaust set up but it won't be too much when compared to the Pypes. This exhaust or the Magnaflow would be a great upgrade from the Pypes system and will definitely sound amazing with an H-pipe and long tube headers.

    I have a 94 cobra it has long tube headers and catless H-Pipe with flowmaster 40 series catback exhaust. I want to change to SLP would the catback system bolt directly up like the flowmaster did?

    im trying to find a nice deep and loud cat back for my 1996 gt and I know the slp can definitely do that but im just wondering what's the difference between the slp Loudmouth 1 and 2?

    • The Loudmouth 1 will utilize resonators that are an open chamber, with no baffling or sound deadening material. The Loudmouth 2 will use a perforated tube and sound deadening material, similar to a glasspack.

    If I put one in my basket and check out is that a pair? Or will I have to purchase 2?

    • Hello, yes this would be a full cat-back exhaust. So it would be both sides.

    Can I put a gt exhaust on a v6 mustang if I buy a tuner along with it? I want to put the slp loudmouth II catback exhaust on my 1996 v6 mustang but was not sure if it would work because it is for a gt mustang. If it will work do I need to buy a tuner with it to modify the fuel effeciency?

    • V6 Mustangs are singal exhaust not dual, you would have to buy a conversion kit, and brackets/hangers for the exhaust.

      Better than expected

      I am very happy with this exhaust, I replaced a rusted out flowmaster with the LM2 and could not be happier, the fit and finish, the hardware, the sound...Oh the sound. It is nice and mellow at idle and just cruising, no droning, but when you open it up, people will notice. I highly recommend this exhaust

      97 cobra alive

      Installed on my 1997 cobra w stalk exhaust manifold as well as midpipe. I have to say install was no problem, the tips look mean, and it sounds even meaner. Went with the loudmouth II and don't worry its just as loud as the lm I's when rev'd out yet quiet enough neighbors don't hate you too much. The kit cam with 2 rubber hangers for the adaptor plate and assume you will be reusing the old hangers, if your car has a number of miles on it I suggest replacing them.

      Great upgrade

      Good sounding exhaust, not loud at idle or cruise. A bit of a bark at engine start, especially when warm. Gets really loud at about 2000 RPM, even under light throttle. Would be much louder with x-pipe or o/r mid-pipe. My car improved noticeably in the 5000-6000 RPM range, still drags, though. Not a difficult install: be ready to drop the axle or cut the stock pipes. Lift and angle grinder highly recommended. Cut the pipes if doing in on ramps/jack stands. The band clamps are VERY good. The high-quality mandrel-bent steel is very smooth and consistent in its shape, also a tad bigger than stock(about .5''). Tips are HUGE. Comes with 4 new ford exhaust hangers, so you'll have to keep 2 of your old ones or buy 2 more. I didn't even remove the tailpipe hangers, just slipped old pipe off and new one on. Worth $550? I wouldn't say so, directly. It's worth the extra $170 compared to, say, the Flowmaster American Thunder cat-back. By the time that cat-back starts rusting, this one won't have even been broken-in.

      I received my exhaust quickly as promised and hooked it up on my 96 V6, although I had some trouble with the x-pipe i purchased, not from AM, the exhaust sounds awesome, well worth the money, no rasp and very loud.

      My brother put this setup on his 95' Cobra bolted up to a off-road X, Oh my GOD, these pipes straight up create a loud crisp sound you cant get with any other set of pipes. Looking forward to bolting them up on my 95' GT.

      SLP Exhaust!

      The product is very good. If u want it to roar and sound like old school muscle, I will have to ask you to also buy the X-pipes too. It will make it sound like a beast. I got the one without cats, but if u do get that one than u cant pass smog and u will have to put on your old cats when u go to smog, or get one with cats! The exhaust will give u a nice deep sound and I would recommend it if you are into sound and quality.
