[heusing240i]

Food for thought, I live in Buffalo, NY and my dealer doesn't allow any mods. I'm still under warranty on my 18' m240i and I'm running BMS CAI, VRSF cat less DP with JB4 tune. Bought tune combo with DP through Mike-XPH for a total around $1000. Added spacer and no CEL so far. One thing I do before inspection is swap Cat (takes less than an hour) and pull out the tune and hide wires. No issues so far, car sounds good WOT, more burbles and sometime backfires (Loud). Well worth the once a year I need to pull take it apart while I'm under warranty IMO.
