SLP Performance M31007 SLP Performance Parts M31007 Loud Mouth Exhaust System

(GT/Mach 1 Loud Mouth (modular)) Built for the (99-04) Ford Mustang... If you're looking for the best-flowing, meanest-sounding exhaust systems in the business, SLP's systems are for you. They use a specially designed resonator instead of a traditional muffler, allowing them to provide unmatched power increases and a "wide-open" sound. Gains of up to 25 HP are possible, depending upon the application. You'll feel--and hear--the difference! They feature: 304 stainless steel, mandrel-bent 2.5" tubing; 3.5" tip, polished Loud Mouth resonators and Loud Mouth II mufflers with SLP's logo embossed in the body; integrated PowerFlo-X Crossover Pipe; double-wall polished tips with SLP's logo; easy, bolt-on installation and SLP's lifetime warranty. All hardware and Installation instructions are included.

  • Ford Mustang (99-04)
  • GT/Mach 1 Loud Mouth (modular)

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!


Ordered a K&N air filter that was $10 cheaper than anywhere else online. Got it two days later, too. I'll be buying here again!

Fast, easy and very competitive prices. The customer service was very good with a quick and helpful response. I will shop here again!

I ordered my shifter last night and I got a tracking number today, shipment seems to be speedy and arrive in 3 days with standard shipping.. cheapest price I can find anywhere!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
