Wagner Tuning BMW N55 Catted Downpipe 200 Cell Sports Cat, SS304, EU6 Coated 135i 335i 335xi E82 E88 E90 E91 E92 E93 Direct Fit Performance Upgrade (500001005)

Wagner Sport Catalyst Front Pipe for BMW N55 135i and 3 Series E Chassis

Unlock quicker spool, stronger mid-range punch and a richer exhaust tone with Wagner’s high-flow sport catalyst for the single turbo N55 engine. This OE-style replacement front pipe uses a 200 CPSI Euro 6 coated substrate housed in 304-grade stainless steel to cut exhaust restriction while keeping emissions friendly. It is a straight swap for the factory cat section, delivering a genuine performance uplift with crisp throttle response and a deeper, more purposeful sound on your 135i or 335i.

Why this upgrade works

• High-flow 200 CPSI sports catalyst with Euro 6 coating for excellent gas flow and clean operation
• 304 stainless steel, corrosion resistant and built for long-term durability
• OE-style fitment points for a true bolt-on install, no cutting or fabrication required
• Less exhaust backpressure helps the turbo work more efficiently for improved torque and power
• Lower thermal load at the turbine outlet supports reliability during spirited driving

We have run this Wagner sport cat on our own builds and many customer cars. Fitment is neat, the finish is premium and feedback on drivability, spool and soundtrack has been consistently positive.
