hello, i currently have a savage .21 and am goin to upgrade to the 25 engine(the hpi engine exchange $100)pretty soon. what is a good pipe that will be pretty cheap? right now i have the stock .21. thanks
RD Logics pipe is good... $50... I didn't like the GPM or the CVEC dual pipes.. makes tuning harder and makes the engine run like crap... and they are like $70...
