right from max power..Max Power in Italy have released their new touring car pipe (EFRA 2664), which now fits perfectly into the Serpent 733. The EFRA 2649 exhaust, which had a long style shape, had a excellent result at the 2009 European Championships, but was too long to fit into the new car from Serpent due to its more forward mounted engine and so the new exhaust solves this issue and yet retains the same characteristics as the longer version.

original long 2649 pipe below..
based on the cars i own and tried this pipeset on..kyosho v-rone rrr,xray nt1,mugen mtx4r,serpent 710,the 2649 pipeset is toooo long and will rub the the left front wheel no matter how you jimmy the exhaust mount wire,it is 10mm longer than the novarossi 2630,2652 and 2660.
try it and you will see,this issue is also posted on the xray forum.
