  1. Quality products, good install and 5 Star Review

    Posted by on 14th Sep 2019

    The install on the header side was flawless. Mating it to my section 2 was not so smooth as they didn't sit flat against each other so some massaging (heat and bending of my section 2) was needed. Parts (flanges, nuts) were high quality.With a dyno tune, I was able to get good gains at the top of the RPM range (>5krpm). Sound is deep on low rpms under load and slowly goes up in pitch as you climb in engine speed. It's got a nice character that's mature, but stronger than stock. I'm using a fabspeed header, sport cats, status gruppe resonated section 2 and OEM muffler.


  2. The sound I was looking for! 5 Star Review

    Posted by on 20th Feb 2017

    After endless search for the perfect exhaust note for my E46, I have found it!

    I spent hours watching videos on YouTube videos trying to find the perfect sound, but they were all plagued with an annoying "raspiness" that seems to be common on any E46 M3 with an exhaust.

    I was referred to Fabspeed by a friend, and I have to say these sport cats along with Fabspeed's headers is one of the best sounds I have ever heard for an E46 M3! Super crisp, deep exhaust note, with no more rasp than the factory setup. Certainly louder, and the car also pulls a bit harder now with less restrictions.

    Nick was a pleasure to work with, easy to communicate with, and understood my wants and needs to a T. Would recommend this system to anybody with an E46 M3!
