Simons 89mm (3.5-inch) muffler: Maximum performance for extreme high-power projects

When it comes to extreme power ranges in high-end tuning and motorsports, the 89mm (3.5-inch) pipe diameter is the absolute pinnacle. To dissipate the massive exhaust volumes from heavily tuned engines without any backpressure, the universal 89mm sports mufflers from Simons are the perfect solution. Designed according to the highly efficient absorption principle, they offer a completely unobstructed passage for minimal exhaust backpressure—essential for coaxing the maximum horsepower and torque out of your setup.

Optimal use of space: All standard shapes made from high-end stainless steel

A 3.5-inch pipe diameter presents logistical challenges in the underbody. To guarantee you maximum flexibility when building your custom exhaust system, we offer the Simons 89mm mufflers in all proven designs:

• Oval mufflers (89 mm): Despite the massive diameter, the oval shape ensures clever use of space to maintain the necessary ground clearance under the vehicle. Perfect as a main or rear muffler.

• Round mufflers (89 mm): The compact, symmetrical version. Ideally suited as a highly efficient front muffler or for uncompromising straight-pipe designs in racing.

All mufflers are manufactured from premium, corrosion-resistant stainless steel. The material guarantees long-term stability against the extreme exhaust gas temperatures (EGT) of large single-turbo setups and reliably protects the system from rust caused by condensation and environmental factors.

The top choice for extreme turbo and displacement conversions

A muffler with an 89 mm inner diameter is used wherever standard 3-inch systems become a bottleneck. The perfect fit for:

• Extreme 4-cylinder projects (e.g., 2.0 TFSI/TSI with large G-series or EFR upgrade superchargers exceeding 600 hp).

• High-performance 5- and 6-cylinder turbos (e.g., Audi 2.5 TFSI, VR6 Turbo, R32 Turbo, Nissan RB26/2JZ) as well as high-displacement V8 biturbo designs.
