Fabspeed now offers 2 exhausts for the G8x platform. The Valvetronic full Catback exhaust and the Valvetronic axle back

Fabspeed BMW M3/M4 (G80/G82) Supersport X-Pipe Valvetronic Exhaust System (2021+)

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
All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty

Fabspeed BMW M3/M4 (G80/G82) Valvetronic Exhaust System (2021+)


The Fabspeed BMW M3 & M4 Valvetronic Exhaust System offers a superb “plug and play” upgrade to the restrictive and quiet OEM exhaust. Adding a significant increase in tone, volume, and power. We use Helical valves imported directly from the U.K. to eliminate any risk of valve failure that plague many other options on the market with low quality exhaust valves.

SOUND:

The Fabspeed Motorsport Valvetronic Exhaust System relieves you of the subtle OEM sound and gives you the volume and tone that’s missing from the factory system. With a slight increase in volume on the throttle and a nice burble at idle, this is the perfect “grand touring” M3/M4 exhaust system. Downshift pops and bangs in sport mode are louder, but not obnoxiously so. This system has no drone at all cruising around town or on the highway.

FEATURES:

Fits all BMW M3 & M4 (G80/G82) sedan/coupe vehicles worldwide (2020+)
Constructed from CNC mandrel-bent 14-16 gauge T304L stainless steel
Laser scanned and CAD designed for perfect OEM fitment using Ametek Handyscan 700
This cat-back system is emissions legal in all 50 states and the rest of the world (ROW)
Uses aerospace quality Helical Limited exhaust valves imported from the U.K.
No CEL (Check Engine Light) guaranteed
Saves 3lbs / 1.4KGs compared to the factory system
Includes Deluxe Quad-Style Tips in your choice of finish
Retains factory valve functionality for “plug and play” installation
All Fabspeed performance products are backed by the Fabspeed Lifetime Warranty
NOTE:

Minor cutting at factory exhaust breakpoint required to install (Reference Dimple Locations on OEM)

I reached out to them today. Price is listed on their website and they are currently offering 10% off during the labor day sale which I was told expires tonight. 6-8 weeks from order to shipping.

Oh man, missed the 10% on website. If I actually had my car now I'd likely place an order but given I'm not even set to start production until the end of this month I'll just hold off for now. Good to know they have holiday sales though, maybe I'll look for a Black Friday sale in a few months.

the video posted on the first post is the only one I have at this time.

[IcebergM4]

It sounds really good! But what happens when you want to add downpipes? Will the sound turn to crap?

But seriously though, at $5K I think I'll hold out to see what Active Autowerke will be offering first

[Limegrntaln]

[BIGW0RM]

5k for THAT?

Hard pass.
