Exhaust dilemma...R1200RT - BMW MOA
Ztechnik also makes a full stainless steel system to fit the RT, I have one on mine. Somewhat less expensive than the big name makers, I'm happy with the Ztechnik overall, just be aware that many tubular engine guards won't work with their header pipes due to the placement of the O2 sensor on the right side pipe. If that's not an issue for you, then you'll likely be happy with the system. Noise level is a bit higher than stock, but not enough to be of any concern, I think it gives the RT just the right exhaust note, but it's certainly not the stealthy whisper of the stock system. They claim slight gains in torque and HP, the big selling point being it weighs significantly less than the stock system. Seat of the pants feel is the torque band is improved over the stock setup, especially between 2000 - 3000 rpm, I can go a gear higher in that range without lugging the engine and it pulls smoothly without downshifting as long as you're not in a big hurry. I track fuel mileage in a spreadsheet and have found zero difference in MPG vs. the stock system.

With 35 plus years of wrench turning under my belt, I'd have to strongly disagree with the first part of that statement. Manufacturers today are faced with the competing requirements of good fuel mileage, maximum horsepower output, and minimum noise and exhaust emissions....
For 2009, the MX-5 has been updated with more performance (complete with a rortier exhaust note), more equipment and styling tweaks. seat-of-the-pants and more »
Everyone else has gone with overhead cams years ago because you can have multi-value intake and exhaust ports which helps make the engine more efficient. and more »
