Well, here we go again another weekend and more stuff gets tested.
This week we go after the noise problem. I've been doing a bunch of testing with my MACS .10-.15 pipe and have grown very fond of it. It makes my boats scream -but is also the loudest pipe I own
I can not afford to loose my test pond so I started looking over my extensive collection of rc car pipes and before I took the drastic approach I decided to try and make a small , lightweight muffler that would not require a 3-axis CNC mill to make.
Did some research on muffler desings and noticed how complicated it would be to make a working tuned resonance chamber in the muffler -so Idecided to go the "glass-pack" route and use a metallic-mesh medium that would cancel some of the noise without being overly resistrictive.
The little muffler did not make an "amazing" difference in the noise but it did take the high-pitch bite that the pipe had without the muffler. Engine seemed to run just like it did without the muffler -no radar gun, eye ball speed seemed tp be the same.
Here are the pics of the Muffler installed on my MACS pipe.
