Get that aggressive and sharp BMW sound without any check engine lights or in cabin drone. The Supersport X-Pipe Valvetronic exhaust slip on system includes Fabspeed's high-performance Valvetronic axle back section and the "Double-X" maxflo mid-pipe for the perfect combination of sound, power, and weight reduction.

SOUND:

This system transforms the M3/M4 into a proper sounding sports car. You’ll actually hear a lot more 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.

POWER:

On our in-house DynoJet, this system made max gains of 25 ft/lbs of TQ at 3,300 RPM and 22 WHP at 5,500 RPM. That’s 26 crank HP! Take a look at our dyno graph and you can see that power is gained throughout the entire power band.

FEATURES:

  • Fits all BMW M3 & M4 (G80/G82) sedan/coupe vehicles including Competition Models worldwide (2021+) (RWD & AWD)
  • Adds an impressive 22 WHP and 25 ft/lbs of TQ
  • 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.
  • 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

TOO SMALL
Size: Medium, Color: Blue
Nice socks, but they are way too small. Says they fit size 6 - 10. I kept 3 ( I wear size 8) and gave 3 to my daughter (size 8.5). We both agreed that they were just too small.

Favorite Socks Ever
Size: Medium, Color: Black/Assorted, Size: Medium, Color: Black/Assorted
I absolutely love these socks, they compress in the middle which is my favorite thing about them! Keeps them from slipping off my feet and also adds support, love love love how they feel and how long they last! This is my second pack that I’ve purchased, I had the multi colored ones before and they’ve lasted me two years before finally starting to wear out and fade and get holes. Definitely going to be routinely buying these every year. Good to wear with my work out shoes...winter boots, Nike sandals, and my everyday adidas sneakers. These are so worth it!
