Description

Meet the MAD B58 Fat Boy 5'' catless downpipe.

The MAD 5 inch Catless B58 Downpipe is a high-performance aftermarket upgrade for BMW B58 engine vehicles, designed to increase power and torque while improving exhaust flow. This downpipe is made from premium quality stainless steel and is precision-engineered to fit perfectly with the stock exhaust system, ensuring a seamless installation process.

With a 5 inch diameter, this downpipe provides unrestricted exhaust flow, which reduces backpressure and increases horsepower and torque output.

This makes it an ideal choice for car enthusiasts who are looking to improve the performance and sound of their BMW B58 engine vehicles.

The MAD 5 inch Catless B58 Downpipe is designed to withstand the high temperatures and pressures of high-performance driving, ensuring reliable performance for years to come. 

Installation of the MAD 5 inch Catless B58 Downpipe is straightforward and can be completed with basic hand tools.

Overall, if you're looking to improve the performance and sound of your BMW B58 engine vehicle, the MAD 5 inch Catless B58 Downpipe is a must-have upgrade. It delivers significant performance gains while also adding a much needed sound improvment.

Expect up to a 30HP increase on a tuned BMW / Toyota Supra B58 with stock turbo, even more on cars with upgraded turbo.
