Assassins HPI Nitro RS4 Evo 3 RTR R/C Car

Hello there! Any update with your RS4 3? I saw the photo on your post and would like to know if the custom exhaust is still working for you? Can you please post what size copper pipe did you use.

I would like this setup on my RS4 3 cause my bodies keep getting really dirty with fuel

Hope you can post Thanks.

Id recomend taking that rear exhaust on the hpi off until you can get a proper rear manifold. Heres mine

Because of that manifold i actually got extra response and torque (I could remove a baffle for extra top speed but i dont do those). Yours looks like it wont let the unburnt oil exit the exhaust and eventually youll just have a nice hot oil tank leaking all over the car.

Thanks for the reply! I know what you mean but maybe the oil will get pushed out with exhaust. Your car is a diffrent model HPI. Yours is the belt driven RS4 2 and the one pictured is a newer model rs4 3 shaft drive. The engine is placed diffrently and it is a totally diffrent paltform.
