Our exhausts are flow-, performance- and weight-optimized. We normally achieve a great performance gain (i.e. about 4-7 HP on 125i and torque gain of about 10Nm) withour the need to modify ECU - just by using the exhaust. Due to the use of leightweight high-tec material, we also achieve a great weight reduction compared to the stock exhaust.
Of course with EC approval (E.E.C. homologation / EG-ABE).
NEW:
Now optionally also also available as flap-controlled exhaust with exhaust valves and Carbon-fiber Tailpipes. With open flaps, the exhaust flow is directed straight to the tailpipes and bypasses the silencer / muffler. So with open flaps the sound is even more powerfull and aggressive. The valve-control can be avctivated via a button so the valves will automatically open at a driving speed of above 70km/h (this behvior is European street legal and with ECE-approval). Furthermore we do supply a wireless remote which allows you to open the flaps at any time (even below 70km/h). The use of this remote is not steet-legal / not ECE-conform.
Exhaust is available for the following 1-series BMW F20 / F21 models (stock cars without tow-bar):
- 114d / 116d / 118d / 120d (N47N)
- 125d (N47S1)
- 114i / 116i / 118i / 120i (N13)
- 125i (N20)
- M135i
These products or components might be produced by third-party suppliers like Bastuck. In some cases there might be the supplier logo on components like the exhaust tips.
These products are approved for shippment and self-installation in your local and professional garages of your choice!
No bigger modifications have to be made to the car!
With the original M-Technik rear bumber you just need to buy the BMW OEM rear bumper insert (diffusor) of the M135i / M140i (which also fits all other modes and perfectly matches to our exhaust) or the BMW M Performance M135i- / M140i-diffusor
Installation should be done by a professional garage - installation instructions can be found here
