Elevate your BMW’s performance and sound without sacrificing refinement or emissions-conscious design with the Untd. Performance Catted Downpipe with Heat Shield, tailored for the S58-powered G80 M3, G82 M4, and G87 M2. Featuring a high-flow 200 cell catalytic converter and integrated heat shielding, this downpipe strikes the perfect balance between power, tone, and drivability—ideal for high-performance builds where quality and control matter.
200 Cell High-Flow Catted Design
The restrictive factory catalytic converter is replaced with a motorsport-grade 200 cell unit, offering significantly improved exhaust flow while maintaining better emissions control than a catless setup. This ensures smoother power delivery, sharper throttle response, and reduced turbo lag—all with a more refined exhaust profile.
Aggressive Yet Refined Exhaust Tone
Thanks to the high-flow catalyst and increased diameter, the S58’s natural turbocharged character is fully revealed—expect deeper tones, cleaner crackles, and turbo spool you can hear. It’s the perfect upgrade for those who want performance sound without overwhelming volume.
Integrated Heat Shielding
Equipped with a laser-cut and form-fitted thermal shield, this downpipe protects surrounding components and helps manage engine bay temperatures during spirited driving and track sessions. The added layer of thermal control supports long-term reliability and performance.
Dyno-Proven Performance Gains
By improving exhaust velocity and reducing backpressure, this catted downpipe frees up horsepower and torque across the RPM range. The result is stronger low-end grunt, faster turbo spool, and a broader, more usable powerband—especially when paired with tuning.
Premium Stainless Steel Build
Constructed from TIG-welded 304 stainless steel, this downpipe is engineered to withstand the intense heat and pressure of high-boost driving. CNC-machined flanges ensure perfect alignment and a leak-free seal, making it durable and dependable under any conditions.
Direct Bolt-On Installation
Designed for OEM-like fitment, this downpipe bolts directly to the stock turbo and exhaust system without cutting or modifications. Plug-and-play performance makes installation clean and straightforward.
