I have had it with the stock headers.I cannot even tighten my stock headers to the cylinder head to get rid of my exhaust leaks.It must be warped or something.I know ATR's are the best but they are 900$ for a set.I was thinking of using a gasket but if this header won't tighten right to the head it won't make a difference.Anybody have Poston headers and are they similar to the stock headers?? I like the stock headers performance wise but all the warping is too much of a hassle.How about the ATR'S any one have them and do they still give that same bottom end response like the stockers do??
