keron Posted October 16, 2017 Author Share Posted October 16, 2017 some wording from another advert I found in japan.... exhaust features a unique power chamber to reduce noise but ensure exhaust flow efficiency and high power output. ^ Heat treat titanium tail for blue flamed finish High quality stainless steel^ Power chamber for increased noise suppression while maintaining exhaust flow and therefore power output JASMA compliance to ensure reasonable noise levels Link to comment Share on other sites More sharing options...
Big Mark Posted October 17, 2017 Share Posted October 17, 2017 FYI The "Power Chamber" is a Helmholz resonator. They are designed to eliminate low frequency noise (drone). They are a calculated specific length so they will bounce the desired frequency back into the original exhaust piping, cancelling it out. So in theory it should be a nice exhaust without the drone. I was looking at the Artec system for my car for the same reason. Link to comment Share on other sites More sharing options...
