I have a Traxxas Nitro Sport SE. I am looking to upgrade it. Will the "Traxxas Aluminum Tuned Pipe/Header Blue" be the best upgrade? This can be found at: http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXJM07&P=7 Also if I buy this, it will give me strong power across mid & upper RPM range. Will this decrese the power form the low to mid range(basically will I have less power and acceleration or the same as before)?
