Updated: Lightweight mids+exhaust V2
Hi all,
As most of you are or are not aware, back in Sept 2012, Lightweight has started changing manufacturers and making improvements to the 1M exhaust system, especially improvement to the raw materials used. Their target benchmark, is nonetheless the god of titanium exhaust - Akrapovic. Fast forward 11 months later (playing the waiting game as well as countless emails in between), Marc has finally shipped the rear exhaust down under. Without further ado, here are some 1addict customary videos. Enjoy !!! Huge thanks to, Lightweight - Marc (Fuchsröhre) Australian distributor - Saurabh (saurabh_turingMS) Active Motorwerke - Steven & Jin (Steven.ActiveMotorwerke & Jin.ActiveMotorwerke) OEM exhaust vs Lightweight titan (catless DP) Road test soundtrack Updated 24/2/14: Lightweight mids+exhaust See post #38 Here are some workshop photos from Active Mortorwerke Last edited by oystero; 02-24-2014 at 08:51 AM.. |

I believe it might be the very best exhaust for the 1M.

Will get Jin to confirm if that "triangle" is used to secure the exhaust No, there is no valve for this (there is however for the M135 exhaust apparently). You are correct, the valve is great for cold start and trying to "stealth" through the neighbourhood. It's a personal choice i guessed. For me, i hardly go over 2000rpm on melb's silly 50km/h and 80km/h roads, so right foot is my valve |

Lightweight web site has some info about the weight savings: says 6.5 kg. less than stock for titanium rear muffler that OP has; and if their full titanium exhaust (which also keeps the stock down pipes; Lightweight offers separate down pipe options though) is chosen then the weight saving over stock jumps to 17.6 kg. Don't know how these numbers correspond to Akra's.

Not sure if minute adjustment can be made. Or i was just lucky that the diffuser and exhaust all lined up According to Jin. That part is weld on to the muffler, it's used to secure the exhaust, it's where the exhaust rubber hanger slides onto. |

The titanium we use is builded in Japan, Special made for the high temperature in exhaust using. Titanium is a fine material, but it's tricky if the temperature grove over 250-300 degree celsius. Normal titanium (Grade 1or 2) can not be used and will brake down after a while. Akra takes also a high temperature Titanium. Valve Control: We thought a lot about this Option and builded two sets of this. But the Sound wasn't as good than we thought. You Need a complete exhaust System to get the 1M louder than Serial. For that, we builded a loud end-muffler. 90% of our customers in Europe take this Option, because the Sound, only made by the end-muffler, is really good and you can save the Money for a complete System.

I have the stainless steel rearbox mated to a N55 midpipe and I'm very satisfied. The Lightweight Exhaust makes an awesome noise under all circumstances - whether you step on it, let go of the gas pedal, heel-and-toe downshifts, you name it. Superb quality for a very fair price compared to other competitors on the market. Cheers |
