I agree 100% my flex is good so far but who really knows how long it will last...my crossover never fit right and still doesn't...front o2 sensor hits the firewall from time to time and I am not going to beat the crap out of my perfect firewall that is extremely stupid...if you look closely at my pictures you will see that the ports do infact not all line up....if we want to compare quality chinese made ebay headers are going to loose imo....do they work for a cheap headers...absolutely just may not be worth your while if you already have a different setup
