Get that aggressive and sharp BMW sound without any check engine lights or in cabin drone. The Supersport X-Pipe Valvetronic exhaust system includes Fabspeed's high-performance Valvetronic axle back section and our "Double-X" mid-pipe that deletes the secondary catalytic converters, for the perfect combination of sound, power, and weight reduction.
SOUND:
This system transforms the M3/M4 into a proper sounding monster. You’ll actually hear some turbo spool when letting off the throttle and you’ll feel the gritty iconic BMW straight six sound coming through the cabin under hard acceleration. Adding more pops and bangs on downshifts and giving a throaty rumble at idle.
FEATURES:
Fits all BMW M3 & M4 (G80/G82) sedan/coupe vehicles worldwide (2021+)
Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel
Laser scanned and CAD designed for perfect OEM fitment using Ametek Handyscan 700
Includes Deluxe Quad-Style Tips in your choice of finish
World's first and only “Double-X” midpipe design includes two investment cast “X” sections for increased exhaust scavenging, resulting in a throaty exhaust note with the least amount of rasp
Uses aerospace quality Helical Limited exhaust valves imported from the U.K.
No CEL (Check Engine Light) guaranteed (on US spec cars)
Saves 8lbs / 3.6KGs compared to the factory system
Retains factory valve functionality for “plug and play” installation
Simple bolt-on installation, no cutting or welding required
