Description
Upgrade your stock B58 downpipe to the MAD B58 4.5" Catted Downpipe and unleash the full potential of your BMW F, G Chassis, or Toyota Supra. Designed to maximize airflow, power, and sound, this downpipe is the perfect performance upgrade for your vehicle.
By replacing your stock catalytic converters with the MAD B58 catted downpipe, you'll eliminate the backpressure that restricts your turbo's performance. This means faster spooling and the ability to achieve maximum power. Plus, you'll notice a significant improvement in the sound of your car, giving it a more aggressive and sporty tone.
With a tuned BMW or Toyota Supra B58 with the stock turbo, you can expect up to a 30HP increase. And if you've upgraded your turbo, the performance gains can be even more impressive. This downpipe is engineered with smooth bends to ensure maximum airflow without any annoying drone, providing a seamless and enjoyable driving experience.
Not only does the MAD B58 downpipe deliver exceptional performance, but it also offers practical benefits. The flex pipe section reduces stress and unwanted vibrations caused by heat and engine movement, ensuring long-lasting durability and reliability.
Rest assured, this downpipe is compatible with both right-hand drive and left-hand drive vehicles, making it suitable for a wide range of BMW F, G Chassis, and Toyota Supra models. Additionally, MAD stands behind the quality of their product with a lifetime warranty on defects and fitment, giving you peace of mind.
