Lots of people here use SD headers, they require some extra effort to get them to fit without hitting anything like massaging the firewall so the 02 doesn't hit against it but its not too hateful that and the flex can go bad but it seems to be a hit or a miss. Another con is they have this ubend/pipetrap in the downpipe, not really a restriction but it hangs kinda low.

Not my pictures but shows what i mean.



Also if you order them from SDs website its 217 shipped.
