My mustang needs new exhaust manifolds there cracked, So i decided to get some headers. But my question is are all the headers the same because BBK headers look nice and are chrome but cost 280.00... PaceSetters headers cost 150 but are they good? Hedman headers cost 215.00, i got all these prices from summitracing.com heres da link. "http://www.summitracing.com/search/Year/2002/Make/FORD/Model/MUSTANG/Department/Exhaust/Section/Headers/Engine-Size/3-8L-232/?Ns=Rank|Asc" But looking at all the headers specs all three brands have different Primary Tube Diameter (in), Primary Tube Gauge, Flange Thickness.. i dont know wats the difference can some one help me, if bbk cost more just cuz of the brand then al go with paceSetters headers or hedman headers.. Has anyone installed any of these headers? I will appreciate any help.
