Untd. Performance Catless Downpipe – Mercedes-Benz CLA/GLA – M270 Engine

Turn up the boost and unlock the true sound and performance of your M270-powered Mercedes with the Untd. Performance Catless Downpipe. Designed for maximum exhaust flow and turbo efficiency, this downpipe removes the restrictive factory catalytic converter—giving your CLA250 or GLA250 a sharper throttle response, faster spool, and a far more aggressive exhaust note.

Key Features:

Catless, High-Flow Design

The factory cat is replaced with a straight-through, free-flowing downpipe that slashes backpressure and dramatically improves turbo performance. Expect quicker spool, stronger midrange torque, and horsepower gains across the rev range—especially with a supporting ECU tune.

Raw, Turbocharged Sound

The catless design unlocks a bolder, more aggressive exhaust note while amplifying turbo whistle and pops under throttle. Your M270 finally sounds like the performance machine it is.

Durable, Track-Ready Construction

Built from TIG-welded 304 stainless steel with precision CNC-machined flanges, this downpipe is made to withstand high temps and the demands of spirited driving or track abuse.

Bolt-On Fitment

Designed specifically for the M270 platform, this downpipe bolts directly to the factory turbo and exhaust system with no cutting or modification required. Smooth install, serious results.

Compatibility:

• Mercedes-Benz CLA250 (C117) – M270 2.0L Turbo

• Mercedes-Benz GLA250 (X156) – M270 2.0L Turbo
  (Also compatible with other M270-equipped models with similar downpipe layout)

Whether you’re building a weekend canyon carver or prepping for a tune, the Untd. Performance Catless Downpipe is the key to unlocking serious flow, sound, and throttle response from your M270.
