Amuse Products Now Available

The R1-Extra is 1.15kg, roughly 2lbs, lighter than the RS-Silent.

Currently we do not have any dynographs for the R1-Extra. Based on the form and design of each exhaust, I think it is safe to say that out of the box, the R1-Extra probably provides a little bit more back pressure and less weight; the RS-Silent has more potential for more power gains with other mods.

With the R1-Extra, when you order the exhaust, for an additional $200 you can upgrade the two 50mm piping to two 60mm piping. This option helps the R1-Extra with its potential for more horsepower gains with other mods.

Once we receive dyno charts from Amuse for the R1-Extra we will be posting those everywhere so keep checking back on our website and threads for updates.



This tip design is going to be standard on all Z34 Amuse exhausts for 2009 and the gold ring option is available for those that would like it .

Because you are saying that we can increase the two piping diameters from 50mm to 60mm but the R1 Extra only has one mid pipe before going into the mufflers. And also u say that the RS Silent has the potential for more power with other mods where as the R1 provides more backpressure...then u say the R1 extra has the potential for more power with other mods once the two pipings are upgraded??? Sorry for the confusion...trying to clear this up in my head. Which one can make more power?
