AWE Tuning Exhaust Suite – BMW M340i/M440i (G20/G22)

OVERVIEW

The AWE Exhaust Suite for the BMW G20 M340i and G22 M440i is a complete cat-back system built around a bespoke stamped stainless steel merge and dual 3" piping — a 65% increase in flow over stock. Choose your configuration above: the Touring Edition with AWE's patented drone-canceling 180 Technology® (offered resonated or non-resonated), or the raw, muffler-free Track Edition. It's a complete cat-back — no separate mid pipe required for either edition. Designed, engineered, and manufactured in-house at AWE's US facility; 50-state legal, No-CEL guarantee, and the AWE Lifetime Exhaust Warranty.

SPECS

• Touring Edition: AWE's patented drone-canceling 180 Technology® for a refined, drone-free daily tone — Resonated (quietest, ideal with a stock downpipe) or Non-Resonated (louder, still drone-controlled)
• Track Edition: straight-through, no resonators, no 180 Technology — the loudest and lightest configuration (11 lb savings over stock), for those who like it raw and rowdy
• 65% increase in flow over stock; max gains of ~16 hp and ~12 lb-ft of torque at the wheels (stock software) — no tune required
• Handcrafted from 3" CNC mandrel-bent, U.S.-made .065"-wall T304L stainless steel
• Quad 102mm double-walled, slash-cut tips in Chrome Silver or Diamond Black, or an OE-tip option, with a stamped AWE logo
• Midpipe inlet adapter bolts to the stock downpipe or an aftermarket downpipe (80mm outlet) — complete cat-back, no add-on mid pipe
• 50-state legal; No Check Engine Light Guarantee; AWE Lifetime Exhaust Warranty (one year on tip finishes)

PARTS INCLUDED

• Complete cat-back exhaust: stamped merge, mid-section, and rear section (180 Technology muffler for Touring, or straight Track Edition section) per selected configuration
• Quad 102mm double-walled tips (finish per variant) or OE tips per selection
