Borla 13-16 BMW 335i / 435i Atak Cat back SS 3.0in, 2.25in 3.5in Tip Single Rolled

This Borla ATAK cat-back exhaust system is built from T-304 austenitic stainless steel, a stronger material than the T-400 series often found in other systems. This choice means it’s more resistant to corrosion and will hold up better over time. The system features 3-inch diameter main piping that steps down to 2.25 inches before the muffler, and then expands to 3.5-inch polished T-304 stainless steel tips, all connected with ultra-smooth, mandrel-bent pipes designed to maximize exhaust flow and engine performance.

Borla engineers spend a lot of time tuning their systems to match the specific personality and performance of each vehicle. For your BMW 335i or 435i, this ATAK system is designed to produce an aggressive, exciting sound that communicates engine RPM and gear selection to the driver, aiding in tasks like rev-match shifting. While it includes a mount for a valve actuator, this specific system does not come with a valve, meaning it will consistently produce its signature ATAK sound.

This cat-back system replaces the factory exhaust from the catalytic converter back. It’s precision manufactured for an accurate fit, and Borla backs it with their Million-Mile Warranty, reflecting their confidence in the durability and quality of their products.
