BMS RACE intercooler J pipe Option:2.5" Pipe Only (Uses couplers from RACE Intercooler) which are known to theDescription 3" J Pipe is only compatible with E series Race intercooler. The factory J pipe is 2. 4" and in some 2010+ models a one piece design. The 2. 5" J pipe is suggested for models that have the one piece design while the 3" J pipe allows you to stay 3" all the way from the intercooler to your throttle body when equipped with a 3" BMS chargepipe for the highest flow potential. We suggest the 3" J pipe for vehicles with aftermarket turbos. Click
