(Loud Mouth II LS1 w/Dual/Dual Tips) Built for the (98-02) Chevrolet Camaro... 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.
