Ielasi Tuned Anti Vibration Kit
A simple and small idea from Ielasi Tuned is this Anti-vibration Kit dedicated for 1:8 Onroad use and their 2185Factory muffler. The kit is composed of two springs and two collars that are used to fix the muffler to the car, dampening the vibrations generated by the engine that could cause the muffler manifold to break. Depending on the length of the muffler support wire (each model has a different one) you can use either two collars or just one to fix the muffler.
