(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.

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!
