  1. Great sound.. 4 Star Review

    Posted by on 3rd Aug 2018

    Just had this recently installed in 2018 M3. Stock exhaust is terrible but this one has elevated things to a whole new level! It really has transformed the car. It now sounds like a proper M3 should. I deducted one star because the only knock against it is that it's not a true quad exhaust (and you can easily tell from looking behind the exhaust tips).


  2. Fabspeed cracked the code for making this inline 6 sound like an absolute monster 5 Star Review

    Posted by on 20th Feb 2017

    I now have an F80 M3 with their valvetronic exhaust system and HOLY S**T it sounds AMAZING... everywhere I go I get compliments which is a very rare occasion with this engine. It's seems the team at Fabspeed cracked the code for making this inline 6 sound like an absolute monster. Bravo!
