SOUL Performance Sport Side Mufflers for 993 Porsche 911 Carrera

SOUL Performance Products Porsche 996 Carrera Sport Side Mufflers are engineered around proprietary drone-fighting mufflers to deliver an exciting, refined driving experience, even on cars running upgraded high-flow catalytic converters. Designed to emphasize the flat-six mechanical tone, these mufflers increase volume and character under moderate to aggressive throttle while maintaining a controlled OEM-plus cabin presence during cruising to avoid rasp and unwanted drone. This configuration is selected for 996.1 (1998-2001) with Polished Chrome X-50 Style Tips, giving the rear of the car a clean, factory-inspired finish with a sharper exhaust note that stays livable for daily use. The system fits Porsche 996 Carreras (1999-2004) and does not fit Carrera 4S (C4S), and it saves 5.1 lb / 2.3 kg versus the factory components (29.7lb vs 34.8lb). Built in-house at SOUL Performance’s Willow Grove, PA facility, it is backed by SOUL Performance’s Lifetime Warranty for both street and track use.

Development

• SOUL Performance Sport Side Mufflers are engineered around proprietary drone-fighting mufflers to maintain a premium driving experience while emphasizing the tone of the flat-six. The design increases volume and mechanical character under moderate to aggressive throttle, yet preserves a refined OEM-plus cabin presence during cruising. SOUL Performance developed these mufflers to avoid the common pitfalls of 996 Carrera exhaust modifications, delivering an aggressive sound without turning raspy or overly loud for discerning enthusiasts. Developed around SOUL Performance Sport Catalytic Converters, the result is a true “gentlemen’s system” that works for daily use without being overbearing, using ample sound-attenuating materials to add sporty tone while preventing drone, rasp, or unwanted frequencies.

Construction

• Each system is built in-house by SOUL Performance’s fabrication team using mandrel-bent 0.065-inch wall, 2.25-inch diameter T304L stainless steel tubing, bespoke SOUL mufflers, and laser-cut brackets. Back-purged TIG welding with ARCAL Prime argon gas promotes proper weld penetration and long-term durability, including demanding track use.

Bolt on and Go

• Each exhaust is built and fixture-tested by SOUL Performance in a thick-gauge aluminum jig to help prevent warping and confirm precise fitment. Every set is rigorously quality-checked prior to shipping, then foam packed to help ensure it arrives in perfect condition. New high-grade bolts, washers, and nuts are included.
