I have the Fabspeed set-up (HFC & X-Pipe) and it sounds GREAT...and that is just going into stock cans....However!...after about 100 miles the CEL was thrown.....we read the code(Secondary O2 cat sensors)....re-set it and I dorve away.....about another 100 miles later give or take the CEL light was thrown again....check the code...same code....called Fabspeed and they sent us extenders for the sensors.....they have been installed and so far so good
I can only imagine the sound of an Eisenmann Race w/this set-up as I had Headers/HFC's/X-Pipe & Eisenmann Race on my E39M5 and it was AMAZING!!
To the guys at Fabspeed...will you be coming to NY anytime soon for tunes?
