SOUL Performance Muffler Bypass Pipes for 997.1 Porsche 911 Carrera S

SOUL Performance Products’ Muffler Bypass Pipes for the Porsche 997.1 Carrera S shed serious weight and unleash a raw, CUP-inspired flat-six soundtrack by replacing the bulky side mufflers with lightweight, free-flowing T304L stainless piping that reuses the factory exhaust tips on S models. Designed as an affordable, high-impact upgrade for aggressive street cars and weekend track builds, the 2.25″ OD straight-through design maximizes flow without choking down to match the OEM outlets, delivering a loud, race-bred tone that comes alive under load. The system bolts up at the factory locations for a direct installation, drops roughly 36.5lb compared to the stock components, and is built in-house at SOUL’s Willow Grove, PA facility from .065″ wall T304L stainless for durability on both road and track. While the aggressive, unmuffled character will introduce some cabin drone especially when paired with high-flow or free flow sections, careful gear and RPM selection keeps it manageable, rewarding the driver with a sharper, more visceral driving experience every time the throttle is opened. As with all SOUL components, these bypass pipes are backed by a renowned Lifetime Warranty for street and track use, making them a compelling, worry-free solution for 997.1 Carrera S owners who want maximum sound and minimal weight while retaining their OEM tips.

Development

• If you’re looking for an affordable and efficient method to increase volume substantially, look no further! This solution is ideal for those with aggressive street cars or weekend track cars. The entire system features 2.25″ OD piping, ensuring optimal flow without restricting exhaust performance for factory tips. However, base models will require aftermarket tips designed for S models or aftermarket exhaust systems.

Construction

• Every set of muffler bypass pipes is meticulously crafted in-house using .065″ thick T304L stainless steel. Combining authentic, rolled-edge, matte-carbon shells with stainless steel creates a distinctively sleek and stealthy appearance, adding a stylish finishing touch to your Porsche 997’s rear end. The white vinyl logos proudly display the SOUL brand, but they can be removed if you prefer a more discreet aesthetic. Each set undergoes rigorous quality checks before being shipped and is carefully packed in foam to guarantee their flawless condition upon arrival.

Sound

• One will experience a CUP-inspired straight pipe sound that will be appreciated! Some adore and desire This exhaust note, although it may be overwhelming for more conservative owners. When combined with aftermarket catalytic converters or race pipes, the aggressive and unrestricted design of the exhaust system results in a loud volume. However, the absence of muffling components leads to the presence of drone, which can be mitigated by maintaining the vehicle within the appropriate RPM range.

Bolt On & Go

• To guarantee an impeccable fit, every set undergoes construction and testing within a robust aluminum fixture, specifically designed with a thick gauge to prevent any warping issues. This meticulous process ensures that each set achieves a flawless fitment.
