Up the aggression and drop weight while unleashing the visceral tones of the N55 engine

There are loud exhausts, there are great sounding exhausts. When you have a loud AND great sounding system....335i OH MY! The N55 has a great voice to match the power it produces, and we wanted to let it sing. Our Muffler Bypass Exhaust System deletes the rear muffler, shedding 14 lbs in the process. This is an exhaust for those who like it aggressive. Expect an intoxicating and menacing barrage of pops and crackles upon deceleration. In cabin tone is very reasonable, with our Sport Cat Downpipe installed we would have no qualms daily driving it at all. 


  • Fits all BMW 335i & 435i (F30/F32) vehicles

  • Saves 14 lbs from the rear of the vehicle 

  • Will make everyone you know envious of the glorious sound errupting from your BMW

  • 14-16ga T304L 3"-2.5" stainless steel piping

  • Includes Deluxe Dual Style Tips in your choice of finish. Available in either 3" Polished Chrome, 3" Satin Black or 3.5" Carbon Fiber

NOTE:  Installation requires cutting the factory exhaust near a factory break point. Everything required for installation is included. The Fabspeed system installs quickly over the factory piping using the included Torca clamp. Reinstallation of the factory rear muffler (for our friends with leased vehicles) is quick and easy!

    As far as loudness goes, it is AMAZING. Definitely makes the car sound the way it should.

    It does drone, however, not as bad as I was expecting. This is my daily driver and I commute about 35 miles both to and from work, mostly highway. Cruising from about 75-80 mph is loud but not obnoxious, turn the music up a bit and it isn't bad at all.

    I had my fiance and mom (both of them are not car people so I expected several complaints) in the car for a 30 minute drive to the furniture store and neither of them complained about it being loud so passed that test!

    Another side note, have had several phone calls on bluetooth and no one has complained about any excessive noise from exhaust (trying to be as thorough as possible lol)

    I think it is well worth it considering how easy it is to DIY (took a little over an hour, but my dad and I were a little over precise with measuring where to cut, could honestly be done in 30 minutes).
