When I was down at GruppeS getting the parts I bought from Rallysportdirectput on.
I had bought a header that was Jet hot coated the header was a Gt spec gen II well when they coated the header the they didnt put a bolt in the O2 sensor so the threads were not useable that stuff is really hard!We tried to tap the threads it didnt work so I called Rallysportdirect and talked to Ben he said dont worry how about you drop ship that header back to him from GruppeS and we will buy you one from GruppeS and credit the difference back on your credit card!
Ben didnt even blink and he had a fair solution to a sticky situation since I was 300+ miles from my home! also they have great deals on parts!
