SLP Performance 31042A - SLP Loudmouth Exhaust Camaro V8 Cat-back System w/3.5 Slash Tips; 1998-2002.
SLP’s F-Body cat-backs have always been the best-performing exhaust systems in the business. Now they’re the most versatile, too! Using our industry-exclusive modular design architecture, we’ve developed a line of systems that can be quickly reconfigured to fit changing performance, noise-level, and sound-quality requirements. Simply loosen a few band clamps, swap muffler types, retighten, and you’re done. No other exhaust offers this level of performance and adaptability!
Along with the included race muffler, the F-Body Loud Mouth system is compatible with our original Loud Mouth II buttlet-type race muffler (#31067). Get both for complete control over your car’s sound and performance characteristics.
NOTES: Includes Loud Mouth resonator. Loud Mouth II race muffles sold separately.
FEATURES:
| Model | Type | Sound Characteristics* | Noise Level* |

History and information about SLP Performance and their products.
Since 2001, LMPerformance has worked closely with SLP Performance to offer customers a wide range of performance enhancements to the American muscle car, the best known of which is its SLP Loudmouth muffler and SLP Camaro systems. With our SLP Performance parts line we have helped customers transform late-model rides into modern muscle cars like the Camaro SS and Pontiac Firehawk.
True to its name, Street Legal Performance (SLP) has a vision "to not just provide performance, but to do so with the best engineering practices and quality possible, far exceeding the industry standards." Impressively, SLP was the first company in the performance aftermarket to develop and manufacture a 50-state emission-legal performance package specifically for V8 Camaros and Firebirds. LMPerformance carries SLP's best-in-class performance upgrades in the following product categories: TVS Supercharger Packages, Blackwing Cold Air Intakes, SLP Exhaust Tips, SLP Loudmouth Mufflers, Powerflo Headers, SLP Accessories, SLP Suspension, SLP Brake Kits and SLP Wheels. The range of applications offered by the SLP line is equally as wide. Below is just a partial list: Chevy Camaro, Corvette, GM/GMC Trucks and SUVs, Pontiac Firebird, GTP, G8, GXP and GTO, Ford Mustang and F-150, Dodge Challenger, Charger, Magnum and 300.

The sound is absolutely the meanest I've heard in a long time. Exceeded my expectations just as indicated by the previous review. The poor little Mustangs pulling up next to me look frightened :)
